Rich,

I thought on the 7A engine on the Audi , the ignition timing is non-adjustable?

At some garages wher super or optimax is sold, the fuel can often be left in the tank for a while as it is not used as widely as normal unleaded. Old fuel can "go off" and lose its octane rating and is therefore in some cases no better than normal unleaded. Best to get the stuff where there is a high density of petrol heads.

Yep, you're right. We have 2 Audi's, mine is the Coupe with the 7A engine, Hazels is an Audi 80 1.8S.........the latter is the one I was talking about. 2 Audi's and 2 Golf GTI's.........I'm just being greedy.  ;D

Apparently Ultimate is only 97RON in the UK but Optimax is 98RON. Stick with Optimax. ;)

Filled my 1993 Golf 1.8 mono-motronic (AAM) engine with BP ultimate, and after about 10 miles the car started to run really badly!! When I take my foot off the accelerator, just as it settles back at idle speed, it starts to shudder and vibrate quite badly, same when accelerating back up again.

When driving though its drives like normal, no improvment. I'm worried though about the shuddering, as its worse when cold. On my model theres no 'check engine' light, so i dont know if theres a fault being registered, and I dont want to pay 60 quid to have vw 'just check' it!!

Once this tank has finished, I'm straight back to normal unleaded!!

How much do you people normally pay for Optimax?
I usually fill up at Tesco and pay about 75.9p per litre. Went to my local Shell garage and Optimax was 86.9p per litre :o :o :o  
Dont care how good it is, Im not buying it til I win the lottery  :P

optimax is much better, I find it cheaper to use over a tank full. But it depends on how your car is tuned - just try and experiment
I don't own this anymore - I just can't be arsed to change the picture
