what the difference between 15% and 20% nitro

[racer1044]

what is the major difference between the 15% nitro fuel and 20%. what does it do to the motor thats different??

[trxrustler11121]

15% nitro will not be as "strong" as 20% nitro. But he 20% also makes the engine run hotter.

20% wil also wear down the engine slightly quicker.

[trxrustler11121]

Heat causes premature engine wear, not the fuel.

The nice thing about higher nitro percentage fuels is that they give more power, allowing you to run *richer* without a drop in performance, meaning your engine gets *more* oil.

Yes. That's correct. More oil >> more lubrication >> happier engine.
