Well, the results on my stock 2014 (factory Fortera tires) aren't comparable.

I have been averaging 21 MPG on interstate driving using "premium diesel" (ie. Cenex Roadmaster XL and KwikStar Premium Gold). I get 17 to 19 MPG in town.

This is somewhat worse mileage than I experienced with driving a rental 2013 Limited V6 approximately 2,000 miles last summer.

I will probably go back to using BP regular diesel next refuel... I got ~24 mpg (interstate) on that.

Re: Miles per Gallon

First nearly full tank MPG calculation. Computer said I was just over 29. Based on fuel pumped I had 28.55. I really topped it off so added a bit more fuel than first fill. Winter fuel and less than 1k on it so far means I am really happy. I keep a spreadsheet of every fill and service I do on my vehicles so I always have an average for the life of the vehicle. Not a big deal but it helped me realize I had something bad going on when the MPG dropped more than could be explained by how I drove on the tank being measured.

I have been driving with the screen that shows instantaneous MPG but my experience with the TDI clued me in as to how to get better numbers. So far I am more than happy.

Re: Miles per Gallon

As mentioned previously if you are a smartphone user there are apps that can keep track of your mileage or all your cars expenses very easily if you're of a mind. I use My Cars but there are many others.

Re: Miles per Gallon

Per EVIC I'm at 21.9 mpg and that's with 75/25 city to highway driving over the last week and a half.

I'll probably have to fill up in a week or so and I'll be able to get a hand calc. Hopefully I'll be able to fill up over the 20 gallons that I put in last time. Was trying to be safe and not try to keep filling once the nozzle kicked off.

Re: Miles per Gallon

I filled up yesterday with 516 miles total on vehicle, 508 on the tank. Took 21.34 gallons to fill up. hand calculated was 23.8mpg, evic reported 23.8. I would say that over half the miles were highway, and the rest were city and stop and go highway.

Cool - I didn't know that's how the Volt was designed.

I guess my thinking was not so flawed after all.

Sorry for the slight thread-jack. As you were.

To contribute a little more to the original topic, I'll say that my EVIC apparently reads about 3% low because over the last 2 tanks it's been virtually dead-on when compared to hand-calculating, but I have 265/65R18s which have a 3.3% larger circumference.

As for my mileage ... I seem to sit at a pretty consistent 24-25 which is a mix of city and highway, usually fairly hilly and usually with ACC set at 78 when on the highway. I consider that quite good considering the speed, hills, winter blend and still basically breaking in.

What kind of premium diesel is that. I get diesel from a station that sells a lot of fuel but is not affiliated with any particular brand and I am getting over 28 going up and down the hills of NE PA. I did not check it during fueling this week when I did a lot of city driving right after a fill up but my trip meter that I reset when I fill up said I was at 21 and that was city driving.

From my experience with diesels, you really can save a lot by backing off on the pedal just a bit especially during the down hill portions. With all the torque you usually can maintain a good speed with less pedal. Also when accelerating it seems to me that I rarely push the pedal down very far. Does not seem to really add to your speed a great deal once you get past maybe 1/4 pedal. Perhaps I am overstating it but one of the things I really like about diesel engines is that unlike gas engines I do not think I ever found it necessary to put the pedal to the floor. Just very slight movements affect your speed far more than is the case with gas.

Right now I am using winter blend so I really do expect that my average is going to creep up if not over 30 MPG. I really would expect far better with premium diesel other than just paying more.

Re: Miles per Gallon

I just turned 4,000 miles over the weekend. 7 fill ups so far. Overall average is 23.31mpg. Best tank was 25.1mpg with city driving and the worst was 21.5mpg with super cold temperatures of that polar vortex and using 4 lo to pull out a stuck vehicle. I pulled an open bed snowmobile trailer with 2 snowmobiles Up North over the weekend and managed just over 20mpg on the highway at 78mph on the way up (up hill) and managed to get 22mph downhill on the way home. I am quite happy with the mileage so far as it is exceeding my 07 CRD Wk which I had modified.

Re: Miles per Gallon

Stopped at a Marathon station last week. The truck was there filling the diesel. I asked the manager about the cetane level. We walked out to the truck. He did not know the cetane level, and it was not printed on his delivery paper work. He did say that in the twin cities, all diesel at all the stations comes from one of 2 refineries. So when I see the list in another thread that lists all kinds of cetane levels, it makes me wonder if it varies region to region. According to what I heard, around here, there should only be 2 cetane levels. I know Kwik Trip has a higher cetane levels than Super America or Holiday. Marathon said they get their fuel from the same refinery as Kwik Trip.

Well, this is the Cenex Roadmaster XL stuff, and this is what the Kwik Trip/Kwik Star chain sells at the station at which I fueled (Performance Gold, 80/20 mix).

Haha, now that there's snow and ice on the ground in town I am averaging more like 15 mpg (city) driving 30 to 45 mph. Could be lower... I will reset the EVIC today and check.

I do like the torque, but I was getting the 21-22 mpg performance from multiple runs using ACC @ 77 mph on a basically empty stretch of I-80 in Iowa at night. Again, stock vehicle & tires, not towing anything. Total distance with premium diesel (over multiple runs on the same stretch of I-80) is about 900 miles.

I concur. Well, with the exception of trying to get it to accelerate through an intersection when another vehicle is approaching. Haha, turbo lag! Maybe I should try Sport mode, or turning Eco off, while in town.

This was anecdotal experience only; perhaps others who are getting better mileage will have better results with premium diesel. However, I performed far more research on this premium diesel (and to make sure it was from "busy" stations so that the 60 million year old oil was "fresh") than I ever did for a gasoline-powered vehicle, so I thought the outcome was ironic. Recently I threw in some random diesel from a Phillips 66 and my mileage jumped up to 24 on the same stretch of I-80.

Ergo in my anecdotal experience premium diesel has been causing me to obtain lower mileage than with random petrodiesel stuff from a station of opportunity. YMMV (haha, literally).

Re: Miles per Gallon

My limited has just about 4200 miles and my overall average is around 26. My daily commute is 48 miles each way, mostly 2-lane country roads (50-60mph). My best highway result was 32 driving back to NJ from Myrtle Beach (600+ miles). Averaged 31 on the way down. When not commuting and using only for short-trips I get around 22-23
