BMW states straight from the manual.
Obviously
and fake news. Buying a 25k vehicle and then "saving" $3 per tank seems completely
to me the manual even states otherwise.
All that says is it'll be down on power..."impair engine performance". Which is true. It even says knocking on hot days is fine, which is
that they say that.
87 is fine. All OEMs know that
s will dump 87 in anything, warranty engine replacement is expensive otherwise.
I don't know to me this seems completely asinine, that's purposefully doing something to save a really trivial amount of money, you buy the more EXPENSIVE CAR that is DESIGNED TO RUN ON 91 or 89 (min), then cheap out and use regular fuel.
I don't think the engine will explode, but more expensive grades of gasoline have better additive packages as well to prevent carbon build ups etc, and BMW engines aren't exactly toyota motors that will last 400k miles, this is a tiny 2.slow with a baby dick turbo strapped to it for power, if you want it to last, you use good fuel, and follow all service recommendations, and use the best fuel you can find to prolong life.
That's what I'd do, but hey... that's just my 2 cents.
