This is the second tank i've gone through since owning the truck. The first tank I got 16mpg mostly city. Than I just changed the fuel filter (which was dirty), and did a oil and filter change, and I just clocked 21 Mpg's mostly city driving. I couldn't be happier about that, these cummins are amazing for the power you have and the economical aspect....

 

Check my sig...... My 94 gets the same.....( If my right foot is feeling lazy... ha ha) !!!! I am getting a new 07. But my 94 will remain in the fleet for my work truck....

nice looking truck.. How do u like the 4" exhaust, i'm thinking of doing a straight 4", maybe a muffler not sure yet.

 

Good deal, can't complain about that mpg.

 

Ever since I put on my DDP3s modified my plate to #100 I've been lucky to break 20mpg. Guess I can't help but push that pedal a little harder to see some black smoke come out. But when my truck was stock (and I drove it softer) I was getting 20-23mpg every tank, I was amazed!! My best was 24.2mpg.

 

I thought I read the gallons wrong or read the miles wrong when I calculated that, but I re-did the math a couple times and when I saw 21 came up, i had a big smile, lol. I'm so use to getting 11mpg with that 350 chevy I had.

 

Ouch. You may even have some speedometer error to raise it higher, next time you're doing a decent stretch on the expressway watch your trip odometer and compare it to the milemarkers. I think my GPS shows about 14% error on my truck... it has 35s.

 

i'll try that^. So if the mile markers go by faster than the trip miles, i guess you either have to measure the feet past the marker that the trip odometer reads a mile to figure out the % it's over.

 

Yea, so say after 50 miles you're 2 miles off, then you have an error of 4%. My truck shows I went 50 miles when I actually went 57 miles, so I add that 14% on to correct my fuel mileage.

 

Nice i'll do it tomorrow, I think 21 is great for the truck, but lets hope it's more, lol.

 

Yea, I remember years ago when my cousin was telling me how these 4wd 3/4 and 1 ton trucks would get over 20mpg... yea right.... Then I read about how the motor can put up with 50+psi! Gotta get one... and years later....
