all xe engines (eg x14xe x16xe x12xe) are all designed to run on 98 octane fuel but will run fine on 95n ron fuel the engine management system just retatds the timing

I heard that BP were bringing out 100ron fuel!!

but does it work though m8?

yeah course, go down to halfords, theirs loads of stuff to choose from to clean out your fuel system, costs from roughly 15quid onwards i think

is there anything else wot can clean ur fuel/injection system??

yep, on my gsi it made a difference, wen i first used it i didnt seem no diff so i went bak to jus normal shell unleaded n then 2-3 tanks later i noticed that the engine wasnt as smooth or rev friendly as when i used optimax.

so what did cossie's do before optimax then???

It does clean out your tank though........i found it out the hard way splutter splutter

on small engines it may give a very slight improvement in response or something, but yea its the big engines like my mums boyfriends sierra cossie that benefit from it most. A lot of people say you cant run a cossie on anything but optimax

In theory in should increase performance, but not on a small engine like yours. It will run smoother after a couple of tanks though. The increased octane rating of Optimax would see a healthy preformance increase on large engines.

it doesnt make fuck all difference to performance but the engine runs smoother.

does this really make a difference in performance, and clean out ur engine, or is it just the same as any old petrol.

cheers
