Engines/tyres/fuel

I am wondering what the best engines, fuel and tyres are for the game. I'm changing all the time and can't seem to find a natural combination.  Any help from seasoned players would be greatly helpful. Thanks in advance.

The engine/fuel/tyres depends from your stats, in the beginning the best is the MURK engine, the rest depends from your strategy 

All my stats currently full as on 2nd last race of the season. Using Murk engines anyways, but sure I read so where people change fuel and tyre suppliers for different races as it helps with the different tracks.
