I get around 500-520 on a full tank regularly.


I'm in socal and driving up to San Francisco in 2 hours and i'm expecting 600+ on a full tank. I'll let you guys know.


Also, just to clarify, I'm always at 80-90+ on the highway, i don't do 75.

I don't expect you to hit 600+mi on a tank driving 80-90mph. Even from Temecula to SF. You certainly won't be driving 80-90mph the whole way (central valley I5, sure, but traffic through the LA basin, and once you hit the Altamont, nope). At those sustained speeds I expect you'll see 36-38mpg.

I say that as someone who's driven plenty of SF bay area to Palm Springs trips. Typically I see better fuel economy from NorCal to SoCal, than the return trip.

Oh I won't drive my usual way don't want a ticket to ruin the trip I'll be going 5-10 over the limit.

600+ is a stretch I take that back. But I hope to get as close to 600 as I can. I'm good at hypermiling

I used to fuel up with Propel since it was cheaper, greener, and on the way to work. Despite the higher cetane, I found out the energy content of Propel wasnt as close to regular diesel. The local Costco now sells diesel, so I just use that with a splash of Opti-Lube Summer+. As of writing, they are the same price.

Diesel HPR: 33.47 MPG avg over 14K
Costco: 37.25 MPG avg over 4K*

*I usually add PS or Opti-Lube to any regular diesel fill. So this number may be inflated, MPG breakdown by additive is below...

Opti-Lube: 35.41 MPG avg over 1.5K
PS DieselKleen: 37.51 MPG avg over 4.5K

Just note the above numbers dont take into account different driving styles, highway vs. city driving, weather, etc.

My most recent 9 tanks have netted me 3626 miles, averaging 402.8 miles per tank and 32.46 mpg. Recently at a range expectation of under 5 miles my car took only 15.0 gallons. That needle can plummet fast toward the end.

LCI, Stock 18" wheels, no additives or tune, no ecopro/ASS, hilly terrain with lots of city driving (very little rush hour stopngo), highway normally approx 60-70mph, often loaded down with about 300lbs of kids and gear.Totally happy with fuel economy, meets expectations.

384 miles with 208 mile range. Ended up arriving at SF with 420 miles done and all mileage after that was city so MPG dropped significantly. But if I continued all highway I'd say I'd easily hit 600.

This is mostly cruise control at 75 with speeds up to 90 occasionally.

Heading back tomorrow but once again the trip is only 420ish miles so far from 600

Why are you dealing with your phone camera at nearly 80mph?
Instead of talking about could've-been 600 mile tanks, just let us know when you actually do it.

To answer the initial question: I fill mine up at a specific Royal Farms around here. The one i fill up is a truck service area so there is always a fresh batch of diesel that is continuesly being cycled through and they have DEF through a pump since it is a truck station. DEF through pump is $2.99 a gal. Additionally, I spoke to the guy that was filling up the tanks and he said that it is unbranded Exxon Diesel. Get an average of 39-40 with all types of driving. Before anyone gets on my ass about calculating it and such, no i didn't, i just go by the average value that is displayed on the trip computer. I never reset it.

I also run a can of seafoam through a tank every 6K-ish miles and change the fuel filter every 30K. I'm at 112K.

I have Nitro V power here in So Cal. Get discount with my Ralph's card or the fuel card plus credit card discount.

First of all, don't worry what I do or don't do on the road, that's none of your business, second of all I never hit 600 because I filled up early, and the road trip was only 420 miles, the rest of the tank was bumper to bumper city driving. But you can see with my trip + remainder of the fuel level that it's very much possible to get to that number

As someone that has lost a family member to a high speed inattentive oncoming driver resulting in double fatality, just keep your hands on the wheel and eyes on the road.

No one cares what your particular fuel economy is, but dont spout that you are getting 600 miles to a tank when you are making inferences based on your fuel guage.

I don't care who you lost. It's 75mph on a 300 mile long two lane road on cruise control in the middle of the desert.

Secondly. You're the one claiming how accurate the gauge is and how amazing it is, but now I'm making inferences.

Haha you've got mental issues dude. I'm done talking to you. If you don't get your way you bring up something else (me taking a photo driving) to change the subject and make yourself feel better.

Seek help.

Showing some true colors there. Overprivileged dbag child loud and clear. Would be nice if you just went back to the Honda forum.

IMO the fuel gauge sucks for accuracy, so learn to read.

Looks like things got a bit toxic in nature, so bringing things back around to some fuel MPG stats. My normal spread of driving is 80% highway 20% city. Any large runs are all highway (say to Flagstaff from San Diego). This is when I hit my best MPG and could have gone for more than I did, but stopped in Yuma from the cheaper fuel.

As Alpine so aptly related in his story, what you do on the road is indeed *OUR* business. Please take some advice from us and settle down, take some defensive driving classes from Bondurant or similar, and be safe.

I told you what I told him. It was 75 on a 2 lane 300 mile highway in the desert with nobody around for miles.

I don't care what you say, nor what you think, there's more important things to worry about other than being petty because my driving record is spotless and I sure as hell know you can't argue that.

Was there one particular fuel supplier/brand you went with?

[dreaming.haze]

I went to the same place for all fillups bar traveling. There is a Valero that is the cheapest in San Diego, high turnover of diesel because of this and seems to be solid fuel wise.

[Enabled]

As tempting as my local Valero is with a great price, $2.62 a gallon.. I avoid it after noticing a significant drop in mpg in my old Jetta TDI with their fuel. It may be coincidental or due to another factor, but I haven't used it in the BMW.

I had a 550mile tank today, with mostly city driving. That was nice.
The tune really helps out. But do your research, as many 328d tunes lose mpg.



I fail to see an actual reason why the LCI would have less mpg ratings. Hardware is all the same, engine management settings are all the same (I've defined and deciphered nearly all the N47 ecu software) and the LL-12 should make it more efficient.. it's a curious thing.

2016 models initially came with LL04 and quickly changed over to 12fe.

The window stickers show a difference in mpg between pre and post LCI. 30/40 for LCI and somewhere around 31/42 for preLCI. Fuelly appears to confirm the difference.
One factor could be the base wheels for LCI are all 18", where base on the 14/15 was a 17" wheel.

[Enabled]

Hmm, they switched all the N47 to LL-12 officially, when looking at the BMW documentation. That is if those cars are still getting oil changes at the dealer. I'm still using genuine dealer LL-04.

That's a good observation, regarding rim sizes. Mine is the luxury line with the ever-so-difficult to clean 18" wheels, but I'm happy with it.

600 miles definitely isn't impossible. I usually use one of 3 local stations (all pretty high volume) and they're all off branded (one is a walmart). Being in a different city every week you can't always choose, I just try to do larger cities if I can, truck nozzles and adaptors are no fun. I also try to avoid the 20% biodiesel blend common in western IL. I've only noticed a bad drop with winter blend, and that was everywhere. 636 miles is my best mpg since tune and was 15.3 gallons, probably need a tow shortly after that! I generally see about 525-550 miles and put 14 gallons in. Trip gets reset and tank topped off every fill up for calculations. 120k and no fuel problems yet... knock on wood. Aftermarket 19" wheels, not staggered. Castrol Pro 5w-30 LL-04 since day one, usually 8-9k between changes.

Definitely a difference between rwd sedan, awd sedan and awd wagon by drive configuration and curb weights. Wheel consideration revolves around weights and tire width, and potentially tread design/compound, aftermarket covers the full spectrum of weights. That being said, my winter wheels are (-1) oem 17" and I don't notice a significant difference in mpg, but dealing with softer compound and winter blend.
