Alright,

I have had this truck for 3 years now, and am wondering what else I can do to make it run for a good long time. Truck has 86,699 miles.

I have changed the fluid in all of the following:
Differentials, transfer case, transmission, power steering, brake system.

I change the oil at the 7,500 mile interval and empty puke bottle;
fuel filter ~15,000 unless I get a bad batch of fuel or mileage goes down.

Stock airbox with stock filter, change as needed or 15,000 miles.

What else should I be checking into regularly? The reason I ask is because the fuel mileage fluctuates from 14-17 around town with an average of 15.

I have been told a 24V should be getting 18mpg. I don't hotrod it, but sometimes I do like to hear the turbo spool...

Thanks!

That is all you probably get around town.
Open road 18-21 MPG
You should change your Transmission filter at least once a year and
adjust the Bands on your Tranny.

So far it seems like you're on top of the maintenance. In town you're not gonna get great mileage but on the interstate you should see around 18. I get around 17.5 overall. Hopefully that'll go up when I get my valves adjusted.

Not fair to compare automatics with manuals. 15 MPG around town is average for heavy populated areas. I live in a rural area and get 16 around town... but only 10 lights in the whole town.

I average 16.7-17.5 mpg on 500 miles tests...depending on how often I have a load in the bed. That's probably 60% Hwy/40% town.

Thanks for the replies.

If I can't get a fleetguard air filter, which do you recommend?

Thanks

When I went with a BHAF, AH19037 Fleetguard number, it raised my MPG by about 2 mpg. They also last for several thousand miles, like a year or more.

What kind of mileage are you getting? Ever do a 500 or 1,000 mile mileage test??

When I drove 15 miles one way to work I was getting 18-19. When I go to Colorado I get 21-22 with cruise set on 80-82. If I take it easy and cruise at 60, I can easily get 23+. Pulling a 35' fully loaded truck and 5er from Colorado Spings over Wolfcreek Pass to Pagosa Springs, I got 12.

Mine averages 15 around town.
