I regularly get between 28 and 31MPG, on a good motorway run using Optimax. Last week filled up with BP SUL and on the same trip from London to York only got 23, my lowest ever (03 MY PPP)

WTF is going on, why the big difference, is BP fuel really that bad?!

It takes a while for the ecu to reset to the new fuel rating or so Ive been told

Thats odd because I get 28 most of the time on BP SUL. I have had 32 on Esso, MY02 PPP. A lot depends how much you use boost though. If you drive at a fairly consistant constant speed with small throttle openings you would be surprised at what you got mpg

 

I've heard many rumours that Esso SUL is 'the best'.
Anyone done any comparisons against Optimax, particularly in a STI7 or 8.
Cheers

 

Esso SUL is best for me (sti7) but I get between 19-24 to the gallon on this stuff. Optimax is noticeably poorer but economy is better. (Just what I've found)

I get noticably more power from optimax

Optimax has more energy per litre than other fuels so it should be possible to get better economy on it, if you can give the loud pedal some self control

Evo had an article a while back on optimax against other fules they got some huge gains on ingear times on the cars they tested
