JET fuel- Just forget it!I've been seeing loads of people with BMW's (M5's, M3's), 07 plate Audi's with big engines filling up at JET. What is up with people?? It's one of the worst fuels money can buy!
Tesco- Although people say supermarket fuel is rubbish, Tesco fuel is 98 RON (don't ask me what that is). The same RON as Shell's. It's just the same quality fuel but for cheaper. High performance car manufactures advise you to use 98 RON because you get the maximum out of your car. The engine should work and last longer.
Shell- Excellent fuel. It powers Ferrari F1 cars so........
Bit expensive though. 98 RON also
All the rest.........I'll let you judge for your self
