what % fuel do you use

[concreat]

hi im a :newb: to nitro trucks and the savage and i wanted to know what % fuel you use. (if the % that you use is not there click on the one closest).

[savagekicknmaxx]

In my savvy I use 30%.

[]-[0pa]0ng]

Same here 30% Rocket Science fuel. Made here is TX.

[Bamasavage]

Sidewinder 30% made in Enterprise, Al. :cool:

[Wannus]

25 % Daytona (protech) competition fuel or 25 % Roga RS25 (italian) in my savy .25

[wullie]

i was told by the guy i bought my savvy off to use 20% cuz thats what he used. its a savage 21. can i go up to 30% like u guys without doin any damage? would i need to change the glow plug? what benefits r there to 30% over 20%?

[Speedster]

I use 20% nitro racing blend from sidwinder.

[crzy-svg-usr]

Ok for all you who know nothing about fuels I'll let you in on some secrets hop move this to a new thread if U like and "sticky" it

It is not harmful for your engine to go from 20 to 30 to 40 to 20 to 10 it does not matter like some say, all that is needed when running a higher percentage nitro fuel is a richer tune, and when going lower a leaner tune. so warm up your engine, you will see it runs hot or cold, and retune to new fuel.

The whole concept behind the tune for different fuels. The nitro percentage is bassicially what is burning in the fuel. When there is 30% nitro, the engine needs less air then if youw ere running a lower % nitro. this is why peopl say they have lower temps with higher percentage fuels, because in reality you are running richer then when you are running a lower %. The reason it is running faster though with the 30 then the 20 is because of the increased nitro amount in the fuel, it burns hotter and produces more combustion, but since the engine is richer it will run cooler then on 20%.

I have run 20% to 40% to 30% in the same engine, its on its 17th gallons now with a great deal of compression. All that is needed is a proper tune, if you can't tune, Id say learn how to or use a trash engine till you do. From my experiences it seems 30% is easier to tune to then 20% because it is running richer, but maintaining same speed as u would with a perfect tune on 20%. of you are odd at tuning though you will have the temp hovering around 210-230 is what I run my engines at and it will run like a dream. Most 2 stroke engines can't idle for a long time, so dont expect it to. If it idles for a long time without bogging down by itself your LSN is probably too lean and you should check that out.

I know for a fact my RB loves a fat low speed needle with a lean high speed for optimal performance. Every engine is different so you will have to figure that out on your own.

For all of the you can't switch fuels and % theorys, they are wrong.

[wullie]

i went in to my local hobby shop today and asked exactly what i asked in m earlier post. all they said was under no circumstances change to 30%!! no explanation, nothing. made me feel like a right prat!!LOL

[savagekicknmaxx]

Your LHS is wrong go in and buy some 30% fill up tune it, run it, and have fun.

[Mondragon]

I run 20 % odonnell's and my truck will idle for as long as you want it to and temps stay the same or fall. when im running it, temps are between 215 to 260 depending on the weather here, if just idleing 195 to 200..

[Revo-World]

byrons 20% for me..lots of power and runs cool

[Savage]

I use 30% Monster. I love it too!

[trashard]

tornado 25% because it`s factory approved.
I`m thinking about switching to 30% tornado.

[Speedster]

Wow, he didn't even tell you why?
that's terrible seriously, I would buy the 30% if i were you.

[4x4]

i use tornado 25% it seems to work well.

4x4

[Dkmode]

I use tornado 20% in both my MT2's T-15 and my Savage's OS30. the sensible limit for the T-15 but maybe a bit low for the OS30

[k0m0d067]

I've only had my truck a couple weeks, so I've only used the 20% as suggested in the manual...

but a buddy of mine gave me a gallon of 40% that I've been hesitant to try...

[Chaos]

40% sidewinder here...11% oil

[silvergagt04]

When I first bought my Savage SS, I was told not to use 30%...they said that the low oil content would ruin my .25. Then I found Byron 25% fuel and it had about the same amount of oil in it then the 15% they recommended. It works good, keeps pretty cool and hauls ***. 30% isn't 25% but its close enough for me.:FarleyParty:

[Pa Matt]

I bought a gallon of 10% today that I'm going to try out. I got to talking with a guy I know that decided to close his hobby shop and focus on his landscaping business. Turns out he has some extra stuff laying around so I bought a gallon of S&W 10% for $8.00. I'm new to the hobby, but he knows what he's talking about and this thread makes me feel even better about it. If all goes well, I might just go buy all that he has left lol

[Jeremy]

please be careful with cheap brand of fule haven't you seen the pic of what it can do to your mill it showes u some in your savage manual

[nitrochevyman99]

Im running 15% but after this gallon im going to go to 20% then after that the next higher but with my 15% and my carb at stock settings it still smokes a bit when i take off is this bad it seems to bog just a bit and wont wheelie

[[hs] darkshine]

sorry to post after ages since the last post, but i've only just got a sav 46!! i'm running o'donnels 25%, and will probably go down to a 20% i used too use 25 in my .15 road car, but in the sav with three speed and ally clutch shoes it just pops up on three quarter throttle!! :)

[R6 DADDY]

hi i just bought my savage x
i was told to use 25%
so i got tornado 25% as hpi themselves recommend in the dvd that came with my truck i am no expert i just goin off the advice i was given myself
chris
:DJjam:

[nath1803]

when i bought my first RC my lhs told me to break the engine in using 15% then run in on 20% for a while and then move up to 25% and so on.
is this corect or can i run my savage on 30% straight from the off?

[[hs] darkshine]

heyy nath welcome!!
most LHS do not recomed changing % fuels too much, bad for your engine, blah blah. from what i have read (here i think, among other places) it doesnt make much difference, the only thing to remember is that a higher % fuel will mneed a richer mixture. what i would recomend is if you did change % fuel, reset all your carbs needles to base and do a thorough re- tune from there. hth! :duel:

[silvergagt04]

30% isnt worth the lack of oil. Stay with 25%. It contains more oil then the 30% and performance is nearly the same. The oil keeps the motor lubed and a lot of 30% has nearly half the oil. Also I stay with the same exact fuel everytime so I dont have the driveablity problem everyone else has. Not all fuels are alike.

[R6 DADDY]

i just stickin to one brand i been told you can change but you probably have to re tune engine which you definately have to do if changin nitro content

[rhett7660]

20% here...

Guys watch out with going from %30 then back to %25 or w/e. I think don't hold me to it but i am pretty sure if you go to a higher percentage of nitro you can't go to a lower percentage of nitro........

[78 K20]

I'v always used 20% (mostly sidewinder), but when I had a pos smartech on road, I bought quart of traxxas 33% to see what would happen, it ran fine on it with no problems, I was expecting something to happen the way the guy at the hobby shop acted when I was buyin it :cool: .

[savagecre]

I use 30%. Was a little confused because My lhs said 20% and the motor's instruction said 20%. Really havent had any problems just I wish I was better at tunning.

I agree 100% but with some added info. You also need to make sure your mill is propperly shimed to run higher nitro percentages and get the maximum out of the fuel with out detonating. Higher nitro fuel also requires different glow plugs, the wrong plug can make temps rise or just not make power.

I personally love Trinity Monster Horsepower 30%. I use it in all of my RC's. I bought my RB modded STS 30 and Rick Brake said to not use the Trinity because it is nasty fuel, only good for cleaning air filters. Rick recommended Byrons or Oddonnells 30%. I guess I am thickheaded because I still use the Trinity .

This is def not true!!!!!!!!!!
You must not know much about fuels urself ! Some engines if you run 30% you need to add shims to the head. Some you need to take shims out when running 20% or lower. As for running 40%to 20% not changing nothing but the tune. You try it and tell me how it works. LOL

So make sure if you give info that is that critical to someone, you do your research first. You don't tune to temps either temps is just a good referance point to shoot you in the right direction. GP's is another facter Whether you run a short or long plug! Must engines run long plugs ecept for O.S.

So all this is facters to take into consederation!

[ntenc1]

WRONG!!!!!!!!!!

You may need to change (add) shims when running higher % nitro. As well as you may need to take out a shim for lower % nitro. Also you should never tune for temp. This should only be a referance point. You should tune for power and smoke, mostly power.

Make sure you know your knowledge before sharing it. This is a very critical thing to tell someone, you urself should do research before you tell everyone else that they are wrong. Plug also make a diff shorter or longer. Most all are longer unless O.S. and just a few others.

I'm using Magnum Fuels 30% nitro. It has 12% oil. They are out of Denver CO. That's what one of the lhs owner uses in his Savages. So far so good and it's pretty decently priced.

Jay

[SDMorris]

As savagekick said, you LHS doesn't know what they are talking about. When I first switched from 20% to 30%, I was into truggy racing. All I did was fill it up, turn it on, let it warm up, and then give it some light throttle for maybe a minute just to wash the motor out of the old fuel. Then I just had fun. Never caused any problems for me.

[AllanQ]

Using Sidewinder 20% but will be switching to 30% sidewinder on my next gallon.

[Shaun]

i've actually never heard of anyone using 5% wouldnt give alot of performance i dont think lol wonder who voted for it?

[stevage]

I'm curious how many of you guys run 20% nitro in the LRP because in the manual it says to run 25% or higher.My local hobby store doesn't sell 25%.

[Wannus]

I am using 16% nitro in my LRP. it runs great, but the temps are rising too high at half tank lean. (first half 80-100C (170-200F) second half 120-130C (245-266F))
i am going to use 25%, it will run cooler withe the same settings, so cooler with the same preformance.
I want it to run between 100-120C (200-245F)
so next time i try 25% nitro.

[AoD]

I run Trinity Monster 20%. I'm still learning to get tuned right with it. Still a newbie myself. But learning more and more each day I'm on this site. :)

Same stuff I use. I've ran all the different percentages, once, I even ran a type of 50% in my RC10, when it had an AE .15 in it. Didn't last long, but ran like hell for about 2 gallons. I used to break my RC10 in on 5% from... I can't remember the maker, but it came in quarts for 11 bucks. 5% nitro 38% oil. Wouldn't run worth a dang but definetly kept the motor lubed on break in. The fuel was most likely designed for break-ins or some really odd style of engine? Anyways, they quit selling it a while ago, so now I'm breaking in motors on 10% traxxas, with the synthetic oil additives they have at the LHS. And to be honest, I never listen to the owner. I'm not sure he knows much about engines in general.

I'm running trinity monster 20% in my savage now, seems to work well. I ALWAYS ran blue thunder 20% in my RC10gt, it just kept good temps and ran nicely even when running it lean. Though, I used to get 3-4 gallons out of a rebuild, since I like it lean lol.

A good quote someone told me about my old Yamaha Blaster.. something to remember..

"The leaner the meaner, the richer the longer" Basically refering to performance over lasting.

My savage runs extremely rich pre-midlean, but is just right after the half tank is gone. Works well in my opinion, gives me a good 5-1o minutes of rich as crap running, to get that motor lubed up nice before I run the crap out of her. This motor I hope lasts a good while. It's the stock SavageX 4.6 motor, and I plan to keep it for a while! :)

I am runnig 30% rite now.

I ran 20% for first couple of years.

[TexasRaider]

Currently run 20% that the LHS sold me with my Savage. Think it is the Eliminator plus which has 20% nitro, 18% oil. Just ordered some Trinity Monster Horsepower 25% and some Trinity Platinum 30% so I will see what those do compared to the 20%. Only bought a quart of each as the 30% only has 8% oil and that makes me a little nervous.

Anybody had any experience with these two? I don't want to totally thrash my engine, but I do plan on installing a Picco .28 sometime in the future so I don't mind running a little aggressive if it will take it for a while!

[paintfumes]

I use 30% Trinity monster horsepower in all my trucks.

[SavageXF4.1]

I heard if you switch from 20% to 30% the piston sleeve expands and there for if you switch back to a lower % you would have the compresstion.

[crzy-svg-usr]

Ok for all you who know nothing about fuels I'll let you in on some secrets hop move this to a new thread if U like and "sticky" it

It is not harmful for your engine to go from 20 to 30 to 40 to 20 to 10 it does not matter like some say, all that is needed when running a higher percentage nitro fuel is a richer tune, and when going lower a leaner tune. so warm up your engine, you will see it runs hot or cold, and retune to new fuel.

The whole concept behind the tune for different fuels. The nitro percentage is bassicially what is burning in the fuel. When there is 30% nitro, the engine needs less air then if youw ere running a lower % nitro. this is why peopl say they have lower temps with higher percentage fuels, because in reality you are running richer then when you are running a lower %. The reason it is running faster though with the 30 then the 20 is because of the increased nitro amount in the fuel, it burns hotter and produces more combustion, but since the engine is richer it will run cooler then on 20%.

I have run 20% to 40% to 30% in the same engine, its on its 17th gallons now with a great deal of compression. All that is needed is a proper tune, if you can't tune, Id say learn how to or use a trash engine till you do. From my experiences it seems 30% is easier to tune to then 20% because it is running richer, but maintaining same speed as u would with a perfect tune on 20%. of you are odd at tuning though you will have the temp hovering around 210-230 is what I run my engines at and it will run like a dream. Most 2 stroke engines can't idle for a long time, so dont expect it to. If it idles for a long time without bogging down by itself your LSN is probably too lean and you should check that out.

I know for a fact my RB loves a fat low speed needle with a lean high speed for optimal performance. Every engine is different so you will have to figure that out on your own.

For all of the you can't switch fuels and % theorys, they are wrong.

Thats funny u posted that at the same time I asked LOL

[crzy-svg-usr]

yeai thought the same thing ha

[D-Sims]

As of today, I run 30% O'Donnell. Switched from 20% O'Donnell after the first two gallons. So far so good seems easier to tune and more POWER!

[Modified Friction]

30% all the way!!! Run's Cooler and MORE POWER!!! Good luck getting any info from your local hobby shop!!!! It's like pulling teeth to get any info from the shop around here!!!!!!

[whipnet]

Gasoline will be more expensive than Nitro soon. haha

I just got the Byron Gen 2 30% blen today but I still have a 25% Byron yet to use. The Gen 2 say much better temps with more horses!!!!Weeeeeeee

[Ozzy-Time:)!]

trinty 20% for me

[Nisse]

I'm gonna run O'Donnell 25% :)

[Mickey]

i run either sidewinder race blend 20% or blue thunder 20% depending on what hobby shop im at when i remember to grab a jug

[alfaracer75]

Been running Trinity Monster 20% but thinking about picking up some 30% next if my LHS has it.

[SL63]

30% Byrons gen 2 lrp spec 3 stage 2 mod
SL.

[pmp]

I use byrons 30%/11%

[stellerrc]

Been using Sidewinder 30%/10% for most big Savvy's and I will usually blend our own here at the shop for our modded stuff. I'm waiting for the new release of a TORCO blend that was supposed to be released last year but was put on hold because of the price of oil and the costs associated with promoting a new product in such a small market place. Since the oil has been cheaper lately I'm waiting to see if they plan on resuming production. Evan Knoll is the man when it comes to making power from fuel!!! I use the Torco blends in my racecar and on our dyno pulls we made 10-15 more HP compared to the leading competitors!!! Cant wait for the release of there R/C fuels!!! I'll bet that his stuff will no doubt be the best you can buy if your planning on winning races or even if you want to beat up on your friends Bashing!!! I'll try and pry the info out of someone and post if there is any changes. PEACE!!http://i403.photobucket.com/albums/pp115/stellerrc/10_12_8.gif

[street doc]

sidewinder 20% love the stuff

[Promc]

Model Technics 25% Big Bang.It was recomended to us by the LHS & we can still get it mail order :)

[wildchild]

I like blue thunder if the lhs has it if not I run top fuel 20 % it is the same as blue thunder

[frddyj]

Trinity Monster 30% which is about the best you can get at my LHS..

Dude i know made mention of getting me some 25% Byrons Gen II :stickpoke:

[alanr]

Just bought a gallon of 30% HPI power fuel. I have been told it is made by wildcat. This is what my lhs is selling so I will see how it is.

[dravage]

i switched from blue thunder 20% to sidewinder 20% and i can see a huge differnce in temps

[Londoner]

O'donnell 25% racing fuel here, never had a problem with it as yet.

Does anybody know the oil % of this fuel? As it doesnt say anything about it on the bottle?

[savageman46]

i switched from blue thunder 20% to sidewinder 20% and i can see a huge differnce in temps

Sidewinder Rocks!! Try 30% next time and you will get even cooler temps.

[DamoSavage]

Started with 25% but now im using 20%

[snake05]

this is wat use on all my nitro
torrnado fuel and now trying the new rapicon both are ok for me

[rc ch]

this is one of the longer living threads i see..... 25% mrf here

[inb4lock]

I run 30%. The last time I was in my LHS, the idiot working at the counter tried to tell me that everyone in the area was blowing up engines with 30%, just so he could sell me a bottle of overpriced 20%. Apparently one of the other numbskull employees ordered 2 4 gallon cases instead of the usual 10 or whatever they purchase, and paid the value of the fuel in Hazmat fees. So now they're stuck trying to sell off 20% fuel for 50 bucks a gallon. I laughed and walked out with my 30%.

[Mickey]

update:::: i have switched to byrons 30% and officially wont use anything else. that fuel is like putting a turbo or blower on your truck imo. can run it leaner with cooler temps

[Pope]

I run byron's 25% pro-driver and love it.

[Winndaddy]

Sidewinder 20% but i want some Byrons 30% from somethings i heard on this thread.

[gofastturnleft]

odonnell 30%

[xll-SavageX-llx]

I use Sidewinder 25% back yard basher

[]-[0pa]0ng]

bryons gen 2 30%.

[JoeGuam]

Muguen Seiki 30= Made by Byrons for Japan cotumers 30% GEN 2.

[NITROMITE]

So it sounds like running a higher% would give you longer run time because you can run rich using less fuel??
Plus it keeps you cooler??
Am i getting this??
I run byrons 30% and never ran another brand or % in any o my mills..

Excpept break in.. I still run byrons 30 so my mill knows what its up against..

[NITROMITE]

Or would running rich use more fuel..yes it will but the rest o what i said is right???
I should have thought on this a bit more before i posted..lol

[Purenitro]

Ok for all you who know nothing about fuels I'll let you in on some secrets hop move this to a new thread if U like and "sticky" it

It is not harmful for your engine to go from 20 to 30 to 40 to 20 to 10 it does not matter like some say, all that is needed when running a higher percentage nitro fuel is a richer tune, and when going lower a leaner tune. so warm up your engine, you will see it runs hot or cold, and retune to new fuel.

The whole concept behind the tune for different fuels. The nitro percentage is bassicially what is burning in the fuel. When there is 30% nitro, the engine needs less air then if youw ere running a lower % nitro. this is why peopl say they have lower temps with higher percentage fuels, because in reality you are running richer then when you are running a lower %. The reason it is running faster though with the 30 then the 20 is because of the increased nitro amount in the fuel, it burns hotter and produces more combustion, but since the engine is richer it will run cooler then on 20%.

I have run 20% to 40% to 30% in the same engine, its on its 17th gallons now with a great deal of compression. All that is needed is a proper tune, if you can't tune, Id say learn how to or use a trash engine till you do. From my experiences it seems 30% is easier to tune to then 20% because it is running richer, but maintaining same speed as u would with a perfect tune on 20%. of you are odd at tuning though you will have the temp hovering around 210-230 is what I run my engines at and it will run like a dream. Most 2 stroke engines can't idle for a long time, so dont expect it to. If it idles for a long time without bogging down by itself your LSN is probably too lean and you should check that out.

I know for a fact my RB loves a fat low speed needle with a lean high speed for optimal performance. Every engine is different so you will have to figure that out on your own.

For all of the you can't switch fuels and % theorys, they are wrong.

Just for clarification, "some" of this info is correct, like the first paragraph, the rest is incorrect, or at least the way it is written is incorrect.

Sidewinder 30% FTW

[nyfreakinrican7]

I started out using 20% then I tried a gallon of 25% which I liked better because the cars had a little more punch. Since I've gotten the savage that has a big block motor I am running 30% Sidewinder fuel. Per the directions that came with my small block motor I have added a shim between the head and block to lower compression slightly so the 30% doesn't damage the engine. And I can buy one type of fuel for all my toys.

[notched306]

im running trinity 20%,after this bottle im going to 30%

[notched306]

well i switched from the trinity 20% to sidewinder 20% and that made a difference.i love the sidewinder alot but i might have to give the byron a try.still gonna switch to 30% on my next fuel buy

[madgadget]

switched from CY heli 30 to SW 30%after talking to Robin. Was not hurting my engine but was not getting it's potentential running that much oil. Still have lot's of heli fuel tho. So I'm gonna practice with it in my race rig and run car SW 30% when racing.
