Reading a number of the fuel reviews available online, and the comments in various forums, it seems that there are "some" opinions that certain high-octane fuels (possibly due to alcohol content levels) are more suitable for turbocharged petrol cars and others for normally-aspirated.
There's no clear evidence or even a consensus, but I detected a "leaning" towards Shell for N-A and Tesco for turbos. Anyone have any thoughts or experiences? As both our cars run better (and almost always) on 99 and we have one of each type I'm interested. As it happens the N-A S8 usually gets fed Shell V-Power and the turbo Volvo usually gets Tesco Momentum, but it's not guaranteed.

Way back in the day, many years ago, once upon a time etc.
When stationed in Germany there was an awful lot of surplus "av-gas" available. It was suspected contaminated and therefore could not be used in aircraft. It just sat in a load of 40 Gallon oil drums. We were warned not to use it in our cars because the octane rating was much too high. Of course some of the lads just used it anyway and nobody that I know of had any problems. The majority mixed it 50/50 with normal fuel. I never did try it, but at the time, though it was rationed we had petrol at one shilling per gallon. (I kid you not, best fags were also one shilling for 20). This of course was leaded.Save</span>
