Gas grade for smart - Smart Car of America Forums : Smart Car Forum

Hi! Does anyone here get mid-grade or, do you all get premium? Was surprised to hear mid-grade might be ok. I don't want to mess up my engine and/or sacrifice better performance by using mid-grade but, if it's not THAT big a deal, I'd rather use it to save $. Thanks!

You have opened a huge can of worms here; many, many threads on this topic. Consensus is, for a couple of bucks per tank, stick with premium fuel.

For this difference less than a Buck a tank = $0.003125 per mile saving, Aproximently

Since you're in PA (east coast fuel) I'd suggest premium. I use mid-grade here in the pacific northwest because of problems I had with my BMW Z4 roadster. It turns out premium fuel up in this corner of the country doesn't meet BMW combustibility standards!

But your not driving a BWM...your driving a Smart.

The POINT, my friend, is that premium fuel in the Pacific Northwest is not the same as premium fuel elsewhere.

The Z4 was a premium fuel vehicle as well. Per the factory instructions, I dropped a grade and all the problems I had with hesitation cleared up.

Not sure what that has to do with using mid grade in a smart in PA but it's nice to know if I ever take the Vette to the Pacific Northwest.
