Anyone running 15/40 diesel oil in their cars? Doing some reading on another site it seems like diesel oil would be a good choice in oil. I have always used mobil 1 of some sort in all of my vehicles. Just curious if anyone has tried this or know if it would be a problem. I dont know if I can post the name of the site on here but most of your probably know anyway....BOB

Just changed to GC today. Before had 10-40 M1. Anway only got like 10 miles on this oil change. I don't care what I"m doing in my car it holds like 65 psi by the stock gauge. I have the TSP ported LS6 Oil pump.......
