Please, Excuse me by my ignorance. I have understood that too much

Octanes can increase the Engine temperature. Is it right?

Is it possible that operation temperature change from 80 oC. to a higher

value using 95 Octanes?

In our cars are recomended 91 Octanes.

What does mean 9.2: 1 compression ratio.?


Thanks.


Mario Farias
