Hey guys about to start changing my own oil and not sure what oil to use. I was going to buy some oil at SAMS club but I don't know which one to get between the Shell Rotella T, the Rotella T4, and the Mobil Delvac 1300 Super? Any input? Thanks!
I use Amsoil in my 2005 GMC 2500HD with their AE filter and have had great results.
Keep it clean and always change the filter with the oil.
Amsoil just came out with a improved version of their diesel oil and I am going to try it at my next oil change.
I recently switched to Amsoil and I'm loving it. I used to use it on my gas trucks before I moved to Hawaii and it was hard to find. Now that I'm back I've renewed my membership and the oil is very well priced.
Edit: I have 3 trucks (2500HD, Silverado SS, Suburban) and I also take care of my brother in law's vehicles (2500HD, HHR) so I buy a lot of oil. The low cost of membership pays for itself rather quickly.
