Any vehicle with a performance motor needs premium fuel to avoid damaging the engine.
These engines run at a higher compression in order to get more power, and the premium fuel prevents engine knock or pinging, the result of premature combustion from less stable fuel in lower octane ratings.
A vehicle with a performance motor doesn’t need to be some luxury line BMW or supercar, either. More common, reasonably priced sports cars also fall into this category.
Motorcycle engines also can benefit, especially ones with high compression engines. By memory I recall my F850GS is rated 5hp less using low octane fuel. It was also recommended to use premium to solve a jerky low rev response I was having, and surprisingly it worked. Not sure if because of the additives (had to seek another brand that had premium) or because the octane.
Real question, no shade at all, just ignorance - why premium? What sort of vehicle is that ideal for, and what is the advantage?
Yeah I could Google but I’m more interested in a human’s thoughts
I have a tune that requires 93. The thing that was interesting is when I put gas in last week I paid 4.79.
Initially regular spiked while premium didn’t move much, it seems like premium has caught up.
Its kinda a weird naming thing, premium doesn’t mean better it’s just the rating and you should always use what grade is recommended for your engine

okay but those are all still toys. is it used for anything practical?
