Premium Fuel for BMW 3 Series?

Hey guys,

Looking at a BMW 330i. I assumed BMWs always used premium gas but have been looking at a few cars and they all indicate regular.

Just wondering what you guys fill up with and if any knocking issues will occur with regular gas?

I think that is an error.

A quick check of official BMW sites say 91 octane is required.

Cool, that’s what I thought. I saw several on auto trader that says regular so for a bit confused.

Yeah crazy right, I had a sales person tell me I can put regular in an E550 a few years ago too, some people are funny.

Yep.

Nah, cause BMWs most BMWs aren't really luxury cars. You can get them with smaller engines, like 1.6L in 3 series and such.

Probably base motor such as 1.5 litre turbo engine that is available in Europe for bmw. Otherwise premium fuel as recommended for 2 litre Turbo and beyond.

I’ve watched an X5 driver fill with regular. When you don’t own the car you just don’t care.

This is really old news. The 3 series (below 335/340) has been requiring 89 minimum (not 91) since the last gen from 2011 (F series).

My last 2012 328 I just put in 89 for the 8 years owned it any had zero issues. No point putting above the requirement for daily thats not driven hard.

Also, the minimum fuel requirement is always printed on the gas cap on your BMW from the manufacturer.

Yes the F3X engine is mapped for 89 octane at a minimum but 91 octane recommended.

Regular is 90 octane in Europe so yes your car needs premium in Canada.

Not true. Europe does not use the AKI (Anti Knock Index) figure that we see here. They use RON (Research Octane Number). "90" in Europe is not the same as "90 octane" here in Canada.
Deal with it.
