It means we can run higher compression in our engines without engine knock, which means we can run our turbos and timing harder on a smaller dispacement engine

It means we can run higher compression in our engines without engine knock, which means we can run our turbos and timing harder on a smaller dispacement engine without ruining it, meaning more efficient engines.
Cleetus McFarland ran a car on brake-clean which has really low octane rating so sure anything works if you care about nothing. https://youtu.be/0hYOgGYQ_c8 https://youtu.be/0hYOgGYQ_c8
American big block naturally aspirated engines will be tuned for crap fuel, if you've got a modern efficient turbo engine you should buy premium fuel to not ruin your engine.
- striking 1y agoI'd love to know which new big block naturally aspirated American cars don't recommend premium fuel. I think the low octane fuel is really only there for the older cars (and for folks who don't understand octane ratings).
- lillecarl 1y agoRecommendations only do so much, 80% of sales are crap fuel. https://www.energy.gov/eere/vehicles/articles/fotw-1270-december-26-2023-premium-gasoline-refiner-sales-have-grown-more-30 https://www.energy.gov/eere/vehicles/articles/fotw-1270-dece... Modern engines will pull back timing and decrease efficiency to prevent breaking down, raising the bar is in everyone's best interest, except the fat and happy Oil companies.
