Ok, I know the smart is rated for an octane rating of 95, minimum 91 (or 92). Today was the first day I have found an octane rating of 94 (usually 92 or 91 is premium here). Of course I thought, why not give it a try, it's only $0.03 more a liter, and if it drops the km/100 L, then I'm game.
Anyone out there got milage ratings for their octane rating for their smart?
Just curious

PS - my two labs just love the back of the smart - they nap, stretch out, and even pop up at key moment to amaze trucks behind me...

i haven't noticed much of a mpg difference so far, i use 93 and 87 octanes. i installed a scan gauge 2 months ago, milage goes down when it's colder. on my stop and go commute a few days ago when it was 58F outside i got 46mpg, at 5F the same commute gets 38mpg. a recent highway trip at 28F was 49mpg, i'll do the trip again next tuesday, it's supposed to be in the 60's.

my turbo smart can make max boost @ 2000rpm, with such small turbos there is no s...

Maybe it's on the same boat as my Brabus the "INDEPENDENCE ll" Due to dock at BALTIMORE, MD on 2/1512009. If you can get your VIN # you could check and see like I did.

These guys have a stage 1 and stage 2 Turbo. Nicely done.

This is very cool, but I think the answer is to Supercharge instead of Turbo. Instant power - no spool-up, and great economy boost. My other car has one and I love it. It's a full size (big) car, and last weekend I got 28.7mpg.Wish I could ge...
