What kinda mileage you guys seeing around town empty, on the highway @ 70-75 and pulling a trailer 10k lbs or more?

Its looking like I am getting around 12 around town driving easy, but its winter so 4wd gets used a little. On the highway I'm seeing about 17 and pulling my 10k trailer I see 13 mpg pulling at 2k rpm.

I'm pretty happy with the towing milage but not with the rest.

'03 with 130K 15 mpg round town, I mean NO highway at all. 18-19 highway unloaded. 11 towing 28 ft. box w/racecar and supplies. I put a Predator programmer on it was worth 1 mpg. Most people with outrageous claims are believing the in dash display.

they may not be lies. fuel mileage will vary depending on what the api is of fuel they are buying.

I don't drive mine that much in a city condition, but you 17 on the e-way is low. I will get 19 to 20 but ya gotta keep the rpm's under 2000, your towing numbers look good.

2007 2WD Classic crew cab. Gets 19-20 in town and maybe 22 on the hwy. Mods are Hypertech tuner normally on stage 2, full MBRP Exhaust. Went from 17.5 to 19 in town when I changed the exhaust.

I can pull 5000, 10,000 or 15,000 it really don't mater if there is a trailer behind it the fuel mileage will drop into the low teens.

'06 lbz engine 2wd crew cab.. hypertech set on stage 3, full 4" mbrp exhaust, egr delete. 15-16 in town with some stop and go driving, 18-19 on highway at 70-75mph, 10-11 with 10,000 lb 28ft enclosed at 70-75 mph.
none of the mods seemed to do much for the mileage, just made it run much better.

Like Mikee said...let the Lies begin!! I guess alot of people are not very good at math!! besides fuel milage in a truck is like big tits on a chic if u get em thats cool but its not a deal breaker. IMO anyways

I will be glad to let you buy me some fuel if you have doubts. I usually fill up around 360-370 miles and it almost always takes between 18 and 18.5 gal. in town. You do the math. I will say this the computer says its getting 19.2 average. I do add 1 pint of 2 stroke oil to every tank.

I like big tits too.

13 around town. Usually 16 on the highway. If you reset the display and keep it at 1600 it will show 21 on the highway.

 

[Driven2xs]

Ever since the cocksuckers changed to low sulfur, my milage fell off.
14.5 if driving unloaded on the highway @ 75.
17 road and local
20 if I am hypermiling (wicked careful) and not going about 1700 rpms.And not going over 50, coasting as much as possible.
Towing a 40' goose at 70-75 I get 12.8.
Hills will kill milage.
