Can someone explain to me in technical terms the difference on the engine between using say RON 95 and RON 97

I believe there was a thread on this some time ago but cant find it

I know the basics but want to know it inside out

Essay to include ignition advance, boost levels and knock, efficiency of burn levels, combustion chamber, etc

 

Hi Steve,

 

Thanks
Cripes - thats a bit of reading!

 

Well you did ask!!! Just a light 40 odd pages - and that's only part 3 remember. Seriously though it's the best source of all things combustion I've ever found on the net (will give you a test next week). David
