premium gas?

I'm 99.9% sure the owner of this thread drives 2011 750i only on this forum

Of course, I pointed the OP to the threads which actually discussed the pros and cons of using premium versus the better burning fuels at the lower octane rating, and even to the Gasoline FAQ which explains exactly what an anti-knock index indicates (hint: it has nothing to do with power, per se, nor of fuel economy, per se).

The OP asked for an opinion on how important premium is - and we all gave him an opinion. To me, gas is gas - but I 'do' fully and completely understand what an octane rating indicates (see the detail in the threads referenced) so I also fully understand those who say to put premium in the car.

Of course, if it knocks on the better gas (i.e., the lower octane fuel), then sure as Christmas, the OP needs to reconsider any of the advice provided ... yet ... if it doesn't knock on the better (i.e., lower octane) fuel, then all the advice given (both pro and con) should be taken into account.

Good luck to all!

And the car show "Fifth Gear" did a octane test and they found that higher octane does give you better mileage and performance but not all premium gas is the same which was interesting.

Agreed.....I even tested multiple premium gas, and swear that i could tell a difference with Chevron premium over the other brands....this was with my porsche twin turbo....to this day Chevron is always my first choice too.....

+3 For this reason I always try to fill up at Chevron although I dont think we can get any ethanol free gas in California.

OP might not damage anything during his ownership by using regular but the next owner will likely face the consequence.
