I have 123,000 miles on my '03 GMC Sierra 5.3L 4x4 that I wanna keep a very long time - 300k or more.
I tow quite a bit and usually run 15-25 mile runs each way. It does not burn oil in even 7-8k runs. It sees -25F to 100F.
I ran GM oil changing every 3k up to 63k, then either Amsoil, M1 or more lately PP changing at 7k on average. Run Wix or EAO Oil Filters & an Amsoil EAA air filter.
Question is with that information:
Would it be advantageous or should I run VSOT (Valvoline Synthetic Oil Treatment)...?
