Nice to see what other ppls are getting. I get around 32 highway and anywhere from 24-28 local. This may have been asked before but how much will an oil change help the mpg?

C230 Sport Coup

Geez I only average about 22 mpg.

guys... do the math.. don't read off the screen... -__-

I forgot to mention that I had/have about 300 pounds of gear in the trunk and a passenger as well.

My car is consistently 6% optimistic in its MPG AVG figure. So yeah that has to be taken into account.

doublestack00

Good, to know. Still not bad though, based on that I would still be getting over 28 mpg.

LILBENZ230

Oh you're right, that's good mileage. But you should test and see if the 6% is just my car or if that's something we can all expect W203-wide.

My lifetime difference in the computer vs calculated is 0.53% That is DAMN accurate. And yes, that 0.53% is more than the calculated. But, the caveat is that is with a mix of E85 and premium. The computer drastically underestimates the mileage on E85 and overestimates for premium. I haven't calculated the difference just premium or just E85, but I would say it is probably pretty damn close to Matt's 6%. If I get a chance I'll separate it out and get back to you guys with a figure.

My car says the range is 454 after every fill up. I have no idea where my car gets that arbitrary figure. It'll go 380 of those 454 on every tank. But I have to be driving pretty much exclusively highway to get above that figure, my record being 502 miles on 1 tank.

doublestack00

My total was 28.9 mpg over 895 miles. Had a passenger and 300 pounds of gear in the trunk with the air on 100% of the time.

Not bad.

Heres a good Q for yall... what is your average since resetting your counters as opposed to showing a "good trip," post your long term overall averages.

LILBENZ230

I'd oblige, but I reset mine after every fill up. And, of course, the "After Start" clears itself after 4 hours of the engine being off. The longest I've ever gone without resetting the one screen was about 900 miles and it was 26.7mpg

In my 2.5L, I have topped at 34.1MPG (93 octane) on a 140 mile trip, averaging maybe 65MPH. I'm very impressed with the fuel efficiency!
