now; that's interesting

I've always tried to use 95 octane, because I like giving the engine an easier time

it probably runs a little bit cooler and has 'less' burn from each compression- I'd always imagined it was sort of 'economy' fuel in terms of head & valve-seal longevity.

Perhaps that's an illusion.

Maybe I'll give high-octane a whizz for a bit, and see what happens
