Correct Fuel for your BMW

Recommended Posts

So I was just wondering if a higher octane fuel will damage or benefit my bimmer,  its my first 2012 x1, currently running on 91 was wanting to see if 95 would be better. Thanks for any feedback.

Hi Nicki, your x1 (regardless of engine size) should be running on premium only (95 or 98).  Ethanol blends or not is not critical.

They tend to knock and run poorly on 91 and you should feel a significant improvement in performance on premium particularly under load.

Personally, I don't find any difference between 95 or 98, so I would run on whichever is available.

Hi there, similar question to above. What is the best fuel octane for a G20 330i.  I was going to go with 95...

Just picked it up on Monday, super excited!

95 or 98 will be fine for it. As above, just skip 91. Enjoy the G20, have had mine for 2 years and still love it

In my e36 I found running on 98 would increase its range by 20 - 30 km per tank which offset the price difference at the time.

Have always run higher octane. Better for the engines in BMW

Not by the time you factor in RUC… 😁

And it was dearer than 91 from the pump a few weeks back!

that is true, easy to fix on old cars though, wire switch into the positive lead going to the odometer 😁
