does everyone waste money on 93/94 (depending where you go) or is it just me? i hear that high octane gas is not as important as you might think. any comments?

check search function, discussed to death... if you dont use premium gas, dont drive a bmw. But serioslly, if you do use lower octane gas, it will just cause poor performance, engine knock, perhaps increased emmissions warnings and maybe a boat load of future problems. Spend the extra $5

It's worth it. You get better throttle response plus smooth sailing (driving

you dont save that much money. Why did u buy a BMW if u dont want to fill it up with premium. The drop in gas milage from using regular probably negates your savings. Try a few tanks of premium and really hand calculate your MPG. If you still think premium is a waste of money fine use regular its your car. I hope its not a lease cuz people like you who dont put in recommend fuel kills the car for the next owner.

I live in San Jose, CA and "Premium" gas around here is 91 which I always use, preferably from Chevron. I heard there are a few gas stations with a 93/94 pump in the South Bay, but I've never tried.

We are lucky to have 96 octane abundantly available. Chevron/Caltex over here offers up to 95 octane as their best. I use the 96 octane and I can really feel the difference from 91 octane...smoother, responsive.
Thanks
Thanks
