Weird, where is it that 91 or 93 octane isn't available? There is one rural convenience store here that only sells 87 and diesel but I can't think of any other place that doesn't offer 87-89-91 choices. 93 is harder to find (and expensive). On Sat, Jul 8, 2023, at 16:09, Dwight Giles wrote: >

Are you at a high elevation? I remember visiting Boulder CO years ago and I vaguely recall the gas sold was between 85 and 89 octane? If 89 is the best you have I guess that makes the decision for you, unless you want to look into using "octane-booster" additives. On Sat, Jul 8, 2023, at

I used to use 91 in my 2005 E320 but no longer available here so I have used 89. On Sat, Jul 8, 2023, 3:00 PM dan penoff.com via Mercedes < mercedes@okiebenz.com> wrote: > I don’t see it any differently than the same car being run on 87. I > wouldn’t advise doing it long term, but as long as

IIRC, you won't get full/optimum performance on lower octane fuel, but the computer will retard the timing to prevent blowing up the engine. On Sat, Jul 8, 2023 at 1:35 PM Allan Streib via Mercedes < mercedes@okiebenz.com> wrote: > Well honestly I don't know. Would a tank or two of 89 hurt

I don’t see it any differently than the same car being run on 87. I wouldn’t advise doing it long term, but as long as you’re not mashing the throttle all the time or running at high speeds or under heavy loads. The ECU would compensate for any difference in fuel quality, I would expect. Not

Well honestly I don't know. Would a tank or two of 89 hurt anything, probably not. In a modern car the computer should compensate. But why did MB specify 91 if they didn't think it was necessary. That is my view. On Sat, Jul 8, 2023, at 13:30, Dwight Giles wrote: > tell me more > > On Sat,
