Good article Paul. Thx returned. Perhaps they don't factor in the heavier foot higher octance brings with it.
I agree with Lorne and Simon, if you wanted to take full advantage of hi octane fuel, you would really need to have your ecu re-mapped....
Quite true. For that reason I still rely on Bosch L-Jetronics. Only 5 sensors, easy to tweak on the road (where fuel quality so often varies), no cats, no lambdas, a wealth of parts available everywhere for nothing (longest used EFI system in history) and a simple multimeter tells all.
