19 mpg
I filled up at a station on the freeway. Then drove 35 miles. I then filled up again. I used 1.83 gal. of gas. I figured I was getting 19 MPG. The truck has a 305 engine with an overdrive trans.

Re: 19 mpg
19 is really good. I got about 16mpg with my 87 GMC (305/700R4) Longbed 1/2 ton.
I would however suggest checking it over a couple tanks. You could have just had a tailwind on that 35 mile trip....

Re: 19 mpg
x2. One trip, one way, is not enough data to be exact. It could still be very close....

Re: 19 mpg
Yeah on a 35 mile trip you can't really get the exact mpg...I'd do a 100 mile trip just for giggles and figure it out that way.
Still *****in' mpgs for a brick rolling down the road. I'm stoked when I see 14 on the freeway and maybe 11 on the street hehe. But then again I have a sticker on my truck which reads "Fu*k Hybrids" hahaha. Posted via Mobile Device |

Re: 19 mpg
ID be glad to see my 88 do more than 12. At least its constant, towing, flooring it, coasting it, always 12mpg.

Re: 19 mpg
GRS
Do you know what rear axle ratio you have? My plans are a 700r4 behind the 250 I6, with 342 gears and see how tt turns out As a side note: I've driven my dakota for too many miles. I've noted that the trans converter goes into lock-up mode at 55, any travel at less than that the fuel mileage goes down the Sh*ter. It seems to have a higher stall than necessary so I'm sure it's not helping. |

Re: 19 mpg
The ratio should be marked on the build sheet in the glovebox

Re: 19 mpg
If I remember correctly my 82 and 87 did not, they just has the code for Standard Ratio.... mine were 3.07 or 3.08 whichever GM uses.
