Hey everyone. This may be a dumb question, but what is the best way to get these trucks to 200-250k all original? I am already changing the oil every 2500-3000 with Royal Purple (considering switching to Amsoil at next oil change), doing the transmission flush every 15k (I also had the Lucas stuff put in at the last fluid change at 87k), transmission filter every 30k (every other transmission flush), coolant every 15k (had it done in April (switched to Prestone) because of mud in the radiator. This was only 12k after the last coolant change.) both differentials as needed, transfer case as needed (had all 3 done last year at 72k), brake fluid was just done after I had most of the system replaced (brake failure x 2 + caliper problems), just had power steering fluid done, etc. Is there anything I am missing? I am trying to keep this truck on the road for a very long time because I like it and I really don't want to have to replace or rebuild the engine or tranny if I can help it. I am also trying to lower my repair bills and keep them low. Thanks.

 

IMHO you're going overboard on each of the fluid changes, but it won't do any damage. With the synth oil you should get 5-6k and you could probably about double the trans and coolant periods. Keep the fuel system in good shape and lube the chassis points. Just about everything else is driving habits and dumb luck.

 

Ok thanks. I was following the severe service schedule in the book. I forgot to mention: Fuel filter around every 10-15k and I do lube the front end when I change the oil.
