99 ram 3500 duelie totaly stock with 429k miles. average 18 mpg at 70,and 20 at 60

 

02' 3.7 v6 gasser. was geting about 12-14 city, 18 straight highway.
got an additive from a man out in houston called "formula v12 lube" and im getting 22 city now. never belived what the gentleman was saying when trying to sell it, but tested and proven works miracles. trucks never ran smoother, and eliminated all friction in the engine. cant wait to do some long trips to test out my highway mpg.

 

when i got my 01 it was completely stock drove it 300 miles up from colorado @70-75 and 25mpg

 

I was in the 20s but since my bigger injectors less now

 

Bone stock, save for an cold air intake and straight pipe exhaust, with an automatic I would get 21 on the highway with summer fuel. Right now I get about 16-18 mixed with winter fuel including idle time. Pen and paper always. Who am I kiddin- calculator I mean.

 

07.5 3500 QuadCab Dually Long Box. Totally stock got 17.3 over Thanksgiving coming home from Ohio empty no bed cover. Normal driving about 14. Pulling a 34ft gooseneck somewhere between 12 and 15k I get 9-11. Want to put mods on but no bucks. Have heard a bedcover can help when not towing so hope to get one and maybe an Icebox intake.

 

05 Dodge Reg. cab long bed Cummins with a 6 speed and 35" BFG's trip from pa to near va. beach va. got between 23 and 25 goin down with a flat bed trailer. comin home with a 2wd reg cab short bed dodge on the trailer got between 20 and 21. around home which is mostly rural driving im gettin 20.4 with a lot of idling on these cold mornings.
this is all based on the computer in the overhead console

 

02 QC LB with 35" tires and a few performance mods gets 15 mpg. Religiously.

88Ford Bronco with 31" tires 17 mpg

84 Mazda B2000 27mpg

01 Kawasaki Concours 45 mpg

 

i have 95 12valve 4x4 that gets a combinied mpg on 24.7 without it id get about 19

 

When I bought my 2006 3500 4x4 I had nothing done to it and I was only getting 15 in city and 18 highway..... Put intake, exhaust, and a superchip with the fuel mileage setting and get 24 highway and 18-19 in city! I recommend at least putting those on! Not to expensive for how muxh you save! I drove to Springfield Missouri with a trailer and drive around 80 mph most the way and still got around 23 highway!
