I'm really sorry to say this but why is fuel economy even relevant for owners of an E class? Is it just for sh*ts and giggles or do you guys actually care?

//flame suit on.

I'm GENUINELY curious here. I certainly haven't looked at fuel economy for a car since I was in University....and I respect differing opinions. I'm just curious here!

Umm, if you are a former Shell/Chevron dealer, you should know the importance of a certain amine particle in the detergent of both Shell and Chevron dealer that helps the detergents survive the initial combustion cycle and thus should help with intake valve buildup as part of those detergents will make it past the PCV valve to get "reburnt" along with all the other crap. The PEA molecule is what is spectacular about Shell/Chevron gas. That said other top tier detergent manu. don't have this so it's a marketing scam.

I would hope you know the above. It's a big deal in the world of direct injected engines, and is a main reason why I do not ever fill up from a non Shell dealer (no Chevron where I live). It's a force of habit when I owned a Direct Injected Audi.

Are you saying then that if there are no Shell or Chevron retailers where you live you should NOT buy a Mercedes?? Of course you aren't. That would be silly. So is the chemistry lesson. I am not a chemist, and didn't claim to be. I responded to a comment about buying at Costco. To repeat, I would not be concerned because Costco almost certainly buys from "a major", and according to the list I linked above, almost all major oil companies make top tier gasoline. They make if because the auto makers wanted some standard for fuel that would not leave combustion chamber deposits. Which one of them is the cleanest of the clean I couldn't say, and quite frankly don't care. If you and other do, that's terrific. I wasn't criticizing anyone or promoting any particular brand. I do know something about gasoline, and my advise (worth what it costs) is to buy top tier premium grade. Anything more is not even implied.

Literally just a game. My old 09 C350 with its V6 and pretty much same horsepower output did the same trip and I was hypermiling and struggling to get past 30mpg. I think my record in that car was 31. Anyway, its cool to me that technology allows me to get the 39.6mpg on the same road. It really is impressive and I also like closing all the three rings on the ECO screen.

No, I'm just saying that if there is a Shell or Chevron fuel retailer nearby, that it would be preferable to go there, notwithstanding the fact that Shell dealers up here in Canada have 0% ethanol in the Premium line (91). I'm unsure about Chevron as it's been several years but ultimately speaking having 100% fuel for DI engines does make a pretty big difference as ethanol adds to the issue of fuel dilution on DI engines, especially since our engines can't enter super lean/high compression modes due to the sulphur content in our fuel. Shell premium is also priced the same as, say, Esso premium, so going out of one's way (for all intents and purposes) to get Shell fuel, as an example, is a win win for both us, our cars, and our wallets.

That's all.

No offense (take the flame suit off! :-), but the implication you're making is people who can afford a higher end car, aren't concerned with fuel economy. Saving money is one thing for sure. But perhaps knowing we're depleting less of the worlds oil and gas reserves is a good thing too?

Yes, for sure. That is a valid point and not one that I have thought of, mainly because (if I'm allowed to be 100% transparent) it is not something I generally concern myself with (and yes, I appreciate that may attract some hate and such but I believe we're still allowed to have our own opinions!)

rbrylaw

You are more than welcome to have your own opinion. For me, I appreciate I can have a luxury vehicle and still help with lowered emissions and gasoline consumption.

Petrol is 6.39USD/usgallon where i live if it was that expensive in your area you'd care or you'd be on the toyota forum discussing your new corolla

Fuel is the least costly part of owning a car even at $6.39 per US gallon. I've had my car for a year. For the year it has averaged about 18 mpg and consumed 168 gallons of fuel at a cost of a bit more than $500. Maintenance including cosmetics costs more than that.

W213Sal

this is only true if you have an expensive car for example i spend about 4% of the value of the car on fuel (around 20,000km/yr @ 4-5L/km @ 1.4€/L) if you drive a cheap car, with a worse fuel economy you'll be spending a much bigger % every year on fuel, i currently spend around 4%, of 60k€ that's around 2000/yr, if I had a corolla I'd be spending the same on fuel but it would be 10% of the value of the car

18mpg is pretty **** poor i get over 55, close to 60 usMPG on my W213

I do all stop and go town driving. A typical trip of a mile or two is only 10 or so minutes. We have lots of traffic signals on 3+ minute cycles.

hows your tire wear been? I rotated mine back in june 2 will probably need to be changed out next year Mine is pretty much all mixed driving, I leave for work around 6:30 and its a 25 min commute with me doing about 140-150kph some of the way then in traffic or at 80kmh rest of the way, on the weekends/evenings there would be a good bit of city driving (public transport is doesn't exist here in any meaningful way)

I have not measured the tread depth, but it seems to be OK. The Florida sun is hard on tires. I usually replace tires due to weathering sidewalls rather than tread wear.
