Unleaded Or Premium

[GWilso]

Hi all,

Sorry if this sounds stupid but has anyone noticed a real diiference between unleaded and premium fuels they claim to add an extra fourty miles to a tank can anyone confirm this or is it just another false economy trick?

it also claims to improve performance and on my 7yr old IS200 I have to wonder if this relative either

Boring subject I know but hey need to know

Cheers

Run a search but I found that mpg did improve, but not enough to warrant the extra amount it costs. I have to use it now as I have a supercharger.

Thanks thought that was probably the case

Have tried most of the "super" unleaded and found not much difference between them, although Optimax was marginally the best.
