MPG's for the 2015-2016 2500 HD 6.0 gas burner

[the sodfather]

Just curious of what folks are getting with the 2015-16 2500 HD 6.0 gas burner. Towing, normal city driving and empty highway running.

[Tbos]

Someone on one of the Chevrolet forums recently said he found out 6.0 wasn't for the engine size when towing. It was for the mpg.

I have a F350 with a 6.2 and I get about 14 mpg daily and 10 or so when towing.

[bsmith0404]

I had an older 6.0, 2002, and got 16-17 hwy empty, 13-14 around town and 8-9 towing. My brother in-law has a 2004 and gets about the same. I have a friend who has a 2014 and it seems the numbers haven't changed much, maybe +1 mpg. The 6.0 has been pretty consistent through the years.

[schwalbach]

I have a 2015 6.0, If I baby it in town 11-12, freeway with no towing 75 mph, 15.5, towing a 2 horse trailer 10, and towing a fifth wheel camper 8 to 8.5.

Very disappointed in mpg, it seems GM could have got it figured out for the empty side with an improvement.

What disappoints me is I work for a trucking company, and our big rigs are pulling 80,000 lbs and getting close to 10 loaded. I realize they are diesel but empty we should be seeing much better than we are out of the 6.0

Oh and by the way I tried a tuner, the tuner box said I gained 2-3 mpg but hand calcs and dash said it never changed. seems they like to over report mpg.

That's very close to the same MPG we got with our 2013 F250 with the 6.2 gas engine. I'd suspect that with the technology available to auto manufacturers today, they're all fairly competitive, so I wouldn't expect you'd see a significant difference in the 5.0/5.3 or in the 6.0/6.2 engine families. Possibly a slight difference with the HEMI engines in solo MPG, but from a towing perspective, it takes a certain amount of energy to move a load. That means the BTU's needed from a gallon of gas to move a 10K trailer with a frontal area of 50 sq ft is going to be the same regardless of which truck is in front of the trailer, so they all will use close to the same amount of fuel to move the same load.

Diesel technology is a little different, between "regeneration/filter cleaning" technologies, fuel used to do that task, gearing and "power band" engineering, there can be a very noticeable difference in towing MPG even though the solo MPG are pretty close to the same among the big 3 manufacturers of diesel engine trucks. So, late model trucks with different exhaust systems can have some pretty dramatic differences in towing MPG.

Good info. Thanks!

Schwalback, I buy everything you said except the mileage on big rigs. A quote from Gizmodo.com echoes the real world: " More than two million semis travel some 120,000 miles apiece along America's arterial highways every year at an average efficiency of just 6 MPG. Six. Miles per gallon of diesel." Believe me, there are no trucking companies hauling 80K getting 10 MPG.

Have a 16 pulling a Carbon 33 getting about 6.5 with no wind and a if it is windy at all 5.7 pulling though the Flint Hill of Kansas, not mountains but pretty hilly. Put K&N filter on help a little. Empty doing around 12.

[SummitPond]

For what it's worth, my 2012 F250 (specs below in the signature area) gets about 12 mpg overall (I don't have a written breakdown separating city/hwy/towing). However, this past weekend (not towing) I averaged 19.7 mpg over 156 miles, mostly highway but some city. I normally don't do this well on the highway, which is why I noted it.

[schwalbach]

NOTANLINES,

Here is a link to the latest on truck MPG, 10 is achievable.

http://www.peterbilt.com/about/media/2014/396/

I work for a large trucking company with in excess of 2,000 trucks, 8 is very achievable and 10 is possible.

[larry337]

Well...I'm a truck driver for probably the largest trucking company in America. I would call 8mpg in long term real world conditions, an unrealistic expectation. 10 is not currently possible. Your article refers to a prototype on one test run. It uses technology that's not currently in full production. And we don't know how much this new technology would cost to build, or how it would perform long term. Currently, I'd say the average is still in the 6-7 range for everyday usage. 8 might happen once in a while but it's not a long term average. At least not yet anyway.

2012 Suburban 2500 6.0 HD with 96K miles. The 6.0 HD hasn't changed much for 2015-16, its a reliable workhorse and detuned for knock tolerance to permit heavy loading with reg unleaded. I averaged 8.5 mpg pulling a 269RB outback from Va to Orlando and back.

You will restore lost mpgs a little by regularly using Techron or a few other additives that reduce sulphur buildup from the back of the valve stem and piston tops. If you regularly use higher octane fuels a do not use at least a top tier detergent gasoline your mileage will get worse with age.

[notanlines]

Schwalback, tell you what I'll do to show you what a fine fella I am. I'll agree that 6 is probably the average MPG on most big rigs.....7 on some, and you ship us some brownies from JJ's Bakery in Marshfield. After the brownies are delivered AND eaten, I'll agree that the MPG is closer to 8 and I'll ship you some genuine Florida Honeybell oranges, direct from the Okeechobee area. How can you turn this down?

[schwalbach]

Notanlines, Here is some reading for you, just send the oranges. JJ's Never heard of them but I see they do exist may have to check them out when you send the oranges send a gift certificate as the MPG's are real as you will see in the reading.

As we are getting off topic here I won't post anymore on this, but we shall agree to disagree on this.

With fuel at 2.50 a gallon, you would recover the $10,000 cost difference in less than 50,000 miles, and really enjoy the towing experience.

I am assuming 12 mpg towing with a diesel.

In less than 50,000 miles TOWING HIS CAMPER. (Assuming your number lbs are correct.)

My capitalization is meant for highlighting not yelling...

Most people that choose a gasser do so because we don't tow all the time.

I have a 2016 F250 gasser and pull a 11,000 lbs TT... and get around 6.5 mpg. However, I only tow approximately 10% of the time.

For me personally, my reason for not going diesel were:
Initial cost
Potential repair costs (HPFP issues not covered by warranty for example)
Short trips (I routinely drive less than 1 mile cold, then shutdown)
I'm not afraid to rev the gasser like it is designed

Not saying a gasser is as good as a diesel. I LOVE the torque of the new ones. However, there are still valid reasons for going gasser.

I can get in the upper teens for mpg on the highway.

Your reasons are exactly my reasons for going with gas.

Those are the same reasons I chose a gas F250 in 2013. We live in northern Michigan, an area where diesel use for short trips is assuredly not a great idea. When we decided to travel more, especially trips in the mountains, our needs changed and that's when we considered a diesel. If we were still going to primarily use the truck for short summer trips within 100 miles of home with an annual longer trip to the southeast, we'd still be driving that truck. But, with the changes, diesel made sense for our situation.

Both gas and diesel have a well deserved "niche" with RV'ers. It really depends on what someone intends to do with the truck both when towing and when not towing... Each is a capable, strong towing machine depending on the use and needs of the buyer....
