20% vs. 30% nitro
I've been using 30, but getting a new engine tomorrow. I want to break it in with 20% because I think it will be getting better lubricated, and the performance will be relativley the same.
Someone correct me if I am wrong. Is 20% just a better all the way around better way to go?

RE: 20% vs. 30% nitro
I'll head over to that site. Cool. I pretty much race at SRS. I'll start hitting Papago's new track layout if he gets it put back together, and maybe the Pit, but mostly SRS.
I'm hoping to hear a lot of thoughts on this nitro thread. I am due for fuel and want a change from the Sidewinder 30 I've been using.

RE: 20% vs. 30% nitro
The only thing that 30% fuel wears out faster is your connecting rod and bearings. Your piston and sleeve is still getting the same exact lubrication regardless of the nitro % (as long as the fuel your using has good quality lubricants) so the piston and sleeve will last just as long on 30% as it will on 20%. There might be a slight difference probably due to the engine reaching higher RPMs but thats about it.
Theres still nothing wrong with 20% nitro. With off-road its more about driver and setup than it is about power.

RE: 20% vs. 30% nitro
You said it.....driver set up. I'm convinced I won't go any faster cuz of the fuel, so why not have better lubricant?? This is the point I am trying to make, just looking for someone to give a good argument in favor of 30%.

RE: 20% vs. 30% nitro
guys honestly if your running 30% youll be better off, i had three RTR engines on 20% and now im on my second race engine on 30%. It runs cooler (yes i mean cooler) easier to tune, and they last just as long if not longer than my 20% engines. honestly ppl freak out about 30% but its not that much of a big deal, just use the 30% and enjoy the benifits.

RE: 20% vs. 30% nitro
Markhat250 it has been proven that 30% fuel is wayyyyy higher in performance than 20%. They dynoed it in RC Driver, and they said it has the same lubrication content as 20% fuel.... just food for thought man.

RE: 20% vs. 30% nitro
yeah I think 25% is the best compromise in turns of performance and engine life.
nitro has nothing to do with engine life, its the oil type and oil percent that effects engine life..
grow some and get the 30%.
most ppl run 20% because of EFRA...

RE: 20% vs. 30% nitro
25% here and never had a problem. I've prematurely broke one con rod in 6 years.
Higher % nitro burns cooler as the combustion temperature of nitro is less than methanol, therefore the more nitro the cooler your engine runs.
You can use 30% and shim you engine, with little loss of longevity, however if you don't re-shim you engine it can kill it quicker. (check you individual engine instructions)
I use 25% cos I believe that shimming an engine reduces the power in order to get more power from the fuel, which seems a bit pointless to me. Plus nitro is more expensive and I can run lower % fuel if I can't get hold of my usual stuff without removing shims.
20% will be fine though. Most engines out of the box will run well on 16%-25% with no adjustments.
