after having my NA Zed for nearly a week and running it on Optimax..put in £110 so far and getting around 25+mpg.

 

what do you run yours on? I wish the 99ron stuff that Tesco does is available up north. Cheapest super unleaded here is Sainsburys at 91.9p/ltr.

 

Does anyone put any addidtives in there fill ups?

mine det likes hell on anything other than optimax

Yet to try Tesco's 99 cos i cant find a Tesco's nearme that sells it :(:(

But optimax all the way :bow:

Which ever fuel I can find with the highest MON levels as RON only give's a better indication of fuel's part knock resistance where as MON indicates it's full throttle knock resistance

Never anything other than optimax or tesco 99ron.

My NA runs happily on 95 octane.

 

Me too :hyper: :hyper:

hi wots wrong with tesco 99ron been using it 4 a while now? should i swap back 2 bp 97ron will it make a difference in performance? cheers
