I just filled up a couple days ago. 12.5 mpg in town... I have a feeling it's due to the transmission. I would love to see mileage in the 20's.

 

seems like evryone gets different mileage and they also don't realize it is in how you drive. i bought this 95 offa my neighbor. he said he got 18-20. didn't phaze me since i'm used to hd 2500 chevy gas guzzler 10-12. the only catch is that the tranny is bad, needs to warm up before it goes into drive. well i got it to my shop and dropped the trans pan, new filter and lucas trans fix and oh yeah i adjusted the bands and now it works like a charm. back to the subject, he bought a 99 5spd. and was complaining he only got 15-16 well i told him to keep his foot off the floormat and he might see a difference. i got 18-22 like he said depending on where i was driving(bfe resident losta short cornerfestival stopsigny roads) well after i modded it up some and especially after the gsk mod i was getting 15-19, well i couldn't help boosting and blowing the doors off all the other oilburners and ricegrinders around here. so 15 sentences to say don't drive like a jimmy dean patty and you will get good mileage, drive like them brown 'n serves and you will see the difference.

 

When I first got a diesel powered vehicle I was getting unrealistic mileage. I was a little unfamiliar with filling a tank with diesel so I wasn't getting it full due to foaming. This brought the mpg's way up because I wasn't actually getting the tank full. I just let it shut off automatically at the pump which was the foam shutting it down and not actually the fuel. When I would figure the mileage I was figuring it with less fuel then I should have been. I figured this out after a few weeks of seeing 25 and 26' mpg's. Once I started letting the foam settle and filling it properly it dropped down to 20 mpg. I am sure the seasoned diesel drivers know this but the newer ones might be doing what I was doing. I also believe you can have two identical trucks drive them the same way and get different mileages. Just because they are the same doesn't mean they are going to get the same mileages. There are too many variables in machining spec quality, assembly quality and other manufacturing qualities which might be within the spec but vary widely. I don't have any faith in the overhead console computer on vehicles either. I had a 1995 Lincoln Continental with a 280 h.p. double overhead cam V8 and the computer on it said I was getting 26 mpg's with my foot buried in it. There was no wasy this was accurate. Manual estimates revealed it was 16 mpg's.
