Fuel economy and improving it, among other things.



The pumps usually have "(R + M)/2" as the formula to determine octane.

Which is why I posted what I did.  Mine is stock, but I can feel the
difference, as well as see the mileage difference...

I am researching the RON statement ATM...

That's why I said in my original post 93 was overkill for a stock 8v. I
can't comment on 16v's since all my cars are 8v's

I still say it's meant for 87 octane gas. Hell a jh is 8.5:1 cr. I think
93
is overkill for the engine and wallet.

ron which i think  is the euro octane rating system and 87 clc which is

we use in north america. so i think 87 is what it's designed for. I'm no
expert so i could be wrong

car
runs just fine. In fact I consider it a waste of money to run a higher
grade
of fuel in a stock 8v. The engine was designed to run prefectly well on
regular grade.
