Over on the atr forum there have been reports of some problems.
Also try and avoid supermarket fuels, you can't go wrong with vpower. BP ultimate is 97 so you may get away with this if theres no shell around like on the mororway or something.
Run it on 99 vpower. Anything less is ***. Tesco 99 if you ate desperate. If you are worried about the price of vpower, you shouldn't be looking at an ATR.
You will get to know the petrol station cashiers by their first names and even end up inviting them to bbqs and weddings, they will become like close family members to you.
Shiny is pretty much spot on. The pres' should always be run on 98+ fuels. The posts can be rin on either as they have 2 maps (or something to that effect anyway). But the pres' should only be run on higher octane fuel. If not it can cause knocking, pinking, pre detonation and in certain circumstances, death of the engine.
Also with a higher octane fuel you should see marginally better MPG, but then again, you'll always want to be in Vtec :lol: BP ultimate has gotten some bad press but it's actually a rather good fuel. It's the same stuff that Sainsburys have in their higher octane petrol. The Tesco stuff has fewer additives than Vpower which make it less 'agreeable' than Vpower. But IMO ANY H22 should always be runb on Vpower.
