Standard unleaded or 97 high octane?

[Nick16valve97]

Hi all - what do you all use re fuel? - and if I use high octane which takes more care of my engine with better performance, is there anything you have to alter on the engine or is it a case of fill up and that's it?

just fill it up.. the knock sensor takes care of the rest..

i used to run on optimax.. but after the last big price hike i've not stepped back up from normal fuel..

Anyway, I think the 8v motor is so much old technology it would run on a coal and wood mix (only in the correct quantities mind!)

16v doesn't have a knock sensor does it Overseer?  I use 95 RON as that's what mine was set up to use, if filled with ultimate or optimax it starts to pink so depends on how the car was set up last.

Amonth ago I would have said it don't matter what petrol you use but after a few tanks of super i've changed my miind

Car feels smoother and I get loads better mpg

I have a 16 valve 97 - so does anything need adjusting?? and how do I check what it's "set up for"?

Mk3 8v,16v, and vr6 ALL have knock control.

try filling up at tesco's there super unleaded is 99 octane!!!!

[Nick16valve97]

is that good for your car? - can't imagine tesco high octane is? - it's like drinking a fine burgundy or a can or special brew - the special brew will get you lagging quicker, but what on earth will it do to your insides over time??!
