Thank you to everyone for the great help.

Actually, the instruction's manual was recommending to use a fuel with 10% to 15% percent nitromethange, so I went to the shop and I bought just that, 10% Omega Fuel. However, as one of you was saying, Omega fuel is an airplane fuel with 18 percent oil, which I think is too much for a car engine. I just bought 16% nitromethane fuel with 12% oil, and I hope that will work.

Respecting which temperature gun I use, I am not sure if I already mention it, but I use a Venom smart temp.

I hope the engine is still ok!

Thank you for all your help. I will keep informing how the engine works with the new fuel.
