RE: 20% or 33% Nitro
....and you don't really get 33% readily available. You probably mean 30%. You may need to put a shim in the head to lower compression for 30% or more, just check you engine manual and see what it says.

Do not...I repeat do NOT listen to Snaut Rockets advice, and I hate to be mean but jonnymac's advice is also no good.
Lets start with jonnymac's thinking there is no 33%. Dude do some reasearch before typing, maybe in the race fuels and more common ones they make 20-25-30, Traxxas offers both 20% and 33% Fuel. Seeings as this is a stock Revo, probably a good idea to think he's using the 20% Traxxas.
Snaut Rocket is also posting some bad advice. Changing fuel percentages from 20% to 30% or 33% does require you to re-tune your engine, thats a fact. However running a higher percentage of nitro will NOT cause your engine to run hotter, in fact you can see temps dropping if properly tuned with increased power from the change. Performance tune the engine after the change, not just temps...then you'll see the difference.
What's better? They are both good options. When you just bash, stick with what you are running, why change? The engines can take changes, just be careful and re-tune.

You can have any percentage fuel you wish if you make it yourself, and maybe a few people do make other percentages, but most shops and manyfacturers sell 16%, 20%, 25% and 30%. Also its true that higher % nitro runs cooler.

I run 20% to 25% nitro in all my trucks and I was told to look at the oil % cuz that's what keeps the engine running longer. I run monster fuel and seems to work for me. I would not run 33% nitro in the winter that could be bad one would think. I found that my little engine makes a lot of power when it's 20F outside but overheated cuz it was to lean[
] and it's very easy to do in the cold.

First of all nice truck.. theres not enough of a difference in the two to change if your just bashin. if its a race truck only and your trying to get everything out of it I would. It will take a couple tanks off the life of your engine. because higher rpm's and whatnot.
