Mileage of 6.4 Hemi

Sounds about right for my 6.4 with a 4.10

8-10 towing a 3500# trailer

I had one of the 3/4 ton gas trucks (2015 Chevy 2500HD SRW with the 6.0L and 4.10's) I commented in another thread that I got 8.0-8.5 MPG towing a 9,000 pound travel trailer. I now have a Ram (2017 3500HD SRW with the 6.4 Hemi and 3.73's) and tow a 10,000 pound 5th wheel. My average mileage is 8.5-9.5 mpg. I've towed the same routes as I did with the previous truck. The only thing I can't account for is whether I've had any different head/tail winds but I'm going to assume they have been similar. So with a little heavier RV that's a little taller but has a more rounded nose I'm getting a little better mileage with the Hemi. Not an Apples to Apples comparison but I'm happy with the results I've been able to obtain.

I agree with Rob.

I like that my 2015 Chevy 2500 6.0 is flex fuel. On E85 I generally have averaged around 11 mpg for all miles, with 13-14 on road trips and in the 8 mpg range towing. That doesn't sound great, but when E85 is so cheap, even with the lower mpg I still spend way less per mile on fuel than using regular, E10, or even if I had a diesel in the pickup. I filled Friday with E85 and it was $1.53 a gallon. The pickup has been on a study diet of E85 for well over a year now. Even a 2000 mile round trip to Wyoming last August, used E85 the entire trip. Actually, it did better t higher elevations than I thought it would. Could be the higher oxygen content of Ethanol. Sounds good anyway.

Mileage on any vehicle is entirely dependent on how much or little brains your right foot has.

I noticed a recent post on mileage of 3/4 ton gas trucks. My truck is a DRW 1 ton CC LB 4x4 6.4 Hemi with 3:73 years. Just returned from a 500 mile trip pulling a 9k 5er and we got 8.9 mpg. I stayed between 62-65 mph. I would think the 3/4 tons would be close to the same. I am very happy with this truck and think the mpg is pretty good. Hope this helps some who are thinking of getting a gas tow vehicle.

Yep, right in line with mine that was 7-9 mpg pulling 12k (21k combined). Usually 8ish. 7 in the hills or wind, 9 in ideal terrain with no wind.

Just finished up a trip yesterday. My 6.4L DRW got 8.9 MPG hand calculated. The TT was just shy of 9k lbs for this trip.

My experience pulling about 12,500# high profile 5er with 6.4 Hemi and 4.10 has been good, but it is thirsty. Towing mileage has varied from as low as mid 6's to almost 9. The average over a trip of over 2,000 miles in varied eastern terrain was almost exactly 8 mpg hand calculated. Most of it interstate at about 68 mph.

I had a 2017 6.4 hemi with 4.10's. I averaged 8- 10mpg, in normal driving conditions towing 6000lbs and 11000lb campers.
