I drive a 1999 GMC Savanna 6.5 TD.
If it is I good shape and you can get the records for it, all the better.
What to watch for?
There really isn’t much. Most of the problems are related to three things; oil changes, oil leaks from the oil cooler seals (easily fixed) and just plain abuse. But with 56K, it may be a really good deal.
I would get the VIN and go to a GM dealer and have them run the VIN against the warrantee records. This will also give you a chance to see if there are any recalls.
Make sure that the oil has been changed on either a 6000 mile cycle or a 3000 mile cycle. Oil changes are the biggest problem with 6.5.
The killer for the engine is the PCM (the thing mounted to the IJ pump) that gets so hot it burns up. Oh the other thing is the lift pump may go bad at 100K.
OK mileage, I get 17 MPG loaded and 17 MPG unloaded. If I idle my mileage drops a lot. The funny thing is when it I loaded with 2000lbs, it get upper 17. Don’t know why and honestly don’t care as long as it continues.
A couple things to remember, there are two batteries, one under the hood and another mounted on the left frame rail. I would replace the one on the frame rail before winter unless the battery is new. Also get yourself a few fuel filters and keep them in the truck. For some reason if you run out of fuel, you may need to replace the filter.
I have to add one morething, the 6.5 is not a bad engine. by 2000 they worked out a lot of the bugs form the change over, 6.2 to 6.5
