so last nite i'm just reading thru the manual and in the general maintenance section 1-61 "Fuel and Engine oil Recommendations" it says,

"vehicles equipped with DOHC engines have been designed to run on unleaded fuel having a minimum octane rating of 91 or 95 RON (research octane number)."

is this really true or just a preventive maintenance thing? i usually run 89 in my car, until i get my turbo anyway. what do you think?

i ran 93 for a while and i i put 87 pack in my car i felt a BIG difference i dont think that is true! - but i couldnt believe premium makes you loose power unless your turbo or have new injectors!

Chiltons is wrong.

They are not speaking of the 420A .. they blur the distinction in many places in interesting ways.
