So far 24 in mixed driving, including traffic (conservative driving for break-in period). Best result will be in a few thousand miles. The trick is staying out of that turbo unless its needed and, of course, selective use of 'Dynamic' setting/driving. Direct injection, 8 speed, stop/start, etc. should make a difference. Interesting to see how it plays out.
in most cars the result is the computer retards ignition timing to prevent knock, and you reduce HP and fuel efficiency as a result. Some cars (Audi in particular) are unable to compensate for the lower octane fuel enough and suffer significant knock problems, which will prematurely wear out engine components (primarily the pistons, connecting rods, bearings, and cam shaft), or in some cases cause catastrophic engine failure.Hi Guys ,
right now in Montreal we are seeing Gas prices at 1.28$ - 1.36$ Per liter... seeing that the Stelvio takes premium gas.. can we get away with regular octane ? or possibly 89 ?
