Really don't see much practical difference in using the current gasolines compared to thirty years ago. I do miss 80/87 Avgas though, sure loved the smell of that stuff!I'm sure the quality is much more even nowadays, used to avoid certain brands of gas in the past, one brand would ping and the next wouldn't even though they claimed the same octane.
In my car, blends with alcohol in the higher percentages lower mileage, at least that's what thecomputer says. You guys with the LTDs and SEIscould check that out for us, ARCO fuel has more alcohol around my neck of the woods than other brands. With your trip computers you could get a good handle onincreased alcohol'seffect on mileage.
