High Octane fuel - the facts and the fiction.

[waynne]

So does high octane fuel give more power? Does it make your car more economical? Will it work well in all engines?

Does it say what you thought all along? Do you use high octane fuel?

[fingers]

I have to say that the only car that I have ever known to run any better on the roads for day to day driving is my old Rover, that runs like a bag of nails on 95 RON stuff. But that does have a red sticker in the rear window from the factory saying not to put anything lower than 97RON or 5 star fuel (who remembers that?) in it.

I remember 4 star leaded!

[fingers]

I think leaded fuel came in 2, 3, 4, and 5 star grades.

2 star - 87 octane
3 star - 93 octane
4 star - 97 octane
5 star - 101 octane

I can remember my mum pulling into a petrol station when I was a kid and seeing these on pump.
