tow gas mileage

[NewBlackDak]

You guys are lucky! Our favorite spot takes us from about 4500ft up to about 8000ft up a canyon. We almost always have a strong headwind going up, and the mileage is in the 6-8 range. Coming down is usually around 11.
The Titan isn't really known for good mileage anyway, but I think it's time for some forced induction.

NewBlackDak,

Forced induction is the way go, just don't expect better mileage.
We live at 4500ft and camp at 9900ft. Round trip nets about 8.7mpg

12.4 mpg with my 4.0 tacoma... I'm pulling a jay flight swift 281 bhs...

I've found speed and hills matter more than engine. When I use my FJ, I usually get around 12 mpg. I recently got back from a 3-week trip pulling with a Silverado 3500HD Diesel (crew cab with extended bed). We got anywhere from 9-11 mpg but we went a lot faster.

On the couple times I have went out, I got 16+ but most of that was on mostly level roads doing 55-60. In the mountains, the computer in the X showed between 12-14

Yea, so many variables. Just got back from VA and got 15mpg going through MI and Ohio. Once I hit the hills in PA/WV/VA it went down to 12/13mpg. Doing 65 the whole way. That's with the diesel though. Depending on the combos and location it seems most people fall into the 9ish-15 range. The term hwy milage is a long way off.

I guess I not feeling so depressed. I just completed our maiden voyage towing my Swift 15RBH Baja with a 2012 Nissan X-Terra V6 averaging 62mph for about 1200 miles. I got about 12 MPG whereas I usually get 19 HWY.

We can get between 9-10 mpg @ 55-60 mph. If we are in Montana and driving 65-70 on the Interstate we will get between 6-8 mpg, depending on hills to climb and head winds. Our Yukon XL has a 6.0 Liter, we are maxed out at close to 8,000 lbs in the TT weight.

With my 2004 Silverado Crew Cab, 1/2 ton, 2wd, 5.3L, 3.73 axle ratio, I get between 11 and 12 mpg towing a 2013 17z. I did upgrade the plug wires to Granatelli Motorsports wires (virtually no resistance) and that helped some. Also running a K&N air filter. I am considering changing the muffler to a Magnaflow and possibly getting a power programmer to see if that helps. I think most of the drag is from the wind resistance. I recently towed a 2008 Malibu on a U Haul auto transport and was getting about 15 mpg. This probably weighs at least 2,000 lbs. more than the 17 z. The truck usually gets about 19 - 20 mpg on the highway when not towing.

There are certain conditions where it does struggle somewhat and that results in the transsmission going in and out of overdrive.
