Hey all, I know this answer will probably vary, but that's why it's a discussion post, right? I've got this 2016 CLA 250, w/Sport package, etc. - roughly 67K miles. I recently moved from Huntington Beach, CA to Cornelius, NC and have since seemed to notice a decrease in fuel mileage...or maybe I'm just losing my mind from the move lol. The traffic here is a little bit tighter, and by that I mean not as much interstate driving (more stop and go), so I could see that being a factor. But I did also recently have replaced: the front brakes, spark plugs, front tires, and an air filter. I can't imagine any of those things would be affecting it but this is my first go with this type of car so I genuinely have no idea. I plan on doing the manual calculations to try and determine what I'm getting, but I figured in the meantime I would see what everyone else is getting - and if it's anywhere like the advertised ratings. As I recall it's roughly 24 city, 37 hwy. But I drive one way and back for a distance of 22 miles total for work now and I just don't feel like that should be consuming even close to 1/8th of a tank...🤔

it will run around 20-21mpg (real not gauge) in city drives so if you get 260-270mi for full tank in those conditions that doesnt violate the default 311mi range (23.6mpg) the computer thinks you should get with a full tank putzin around
it is 3400lb or so being rolled around by a little 1991cc mill so …

Same here. If you do mainly stop and go city driving , your gas consumption will be high. Once you hit the hwy, has consumption will go down significantly.

Hi, I hv a small older model Benz that gets excellent mileage with premium gas, usually purchased @ buying clubs as I’m in OC where u used to be! Recently mileage went way down & car started running rough, I spent $2K on repairs probably not urgently needed, only to find that alcohol was being added by these clubs! I’m back to Mobil & it runs like a dream!

oh yeah the c.a.r.b. crap
just surprised sams costco etc dump “other” stuff in their fuel?
i do notice chevron e10 is not ideal but ok and can still extract enough power … but some odd ball unknown joint (that does not get the same delivery tankers) the power band is off … couldnt wait to empty that fill
no e0 pumps near me this e10 corn syrup gibberish is for the birds

One contributing factor is you've moved from sea level to around 800 to 1000' in elevation. Your town is in the foothills of the Appalachian chain. You will consume more fuel at higher elevations even though MB mapping does adjust your fuel/air mix somewhat. Driving up & down hills will also use more fuel than most highway driving on the West Coast. You might try finding non-ethanol stations in your area. You can download the "Real Gas" app on your cell phone. I'm not sure you'll like the prices compared to Costco & Sam's Club but it should improve your mileage a bit. Try to stay with the "Top Tier" companies like Sunoco, BP, Velaro, etc. and calculate whether it's worth the extra money
