Hi there,

As this topic must've been discussed earlier prolly in other threads but I gotta ask couple of questions about Nitromethane. Nitro which mostly I read here is 15% best for the engines and most of the people and senior flyers have been using it either it's 2C engine or 4C engine.

In Pakistan, here we generally prefer and use 80% methanol 20% castor oil mix which is popular in European countries as I read it here and it has a particular name I dont remember it. This exact 80/20 mixture we use it here and we don't use Nitro as its ofcourse expensive here as well, but its available at the LHS who make it locally not company made fuels which are available in USA. A senior flyer who is our friend goes to flying with us, he says Nitro fuel basically reduces the life of an engine either 2C or 4C as he said its his experience. My question is that does really nitro reduce engine's life? As per my knowledge nitro is used as a catalyst and it helps burn fuel more efficiently so engine performs well with higher rpms. Second question is, if we use 15% nitro on any engine after a gallon on it and then we use 80/20 would it make any difference in engine's performance or would it reduce it's life?

Please clarify me as in future in USA I'd like to use nitro in all engines I would use there.

Thanks in advance
