Ive got a 94 LS and I was wondering if it would be ok too run 15-40 rotella in the 1UZ. Im used to 3.8 gm engines and was just curious if it be safe

Its pretty thick oil, you don't want to suffer a cold start problem with oil that thick.
Stick to 5w40 or 10w30 or 5w30, it was just on sale here, and I had a look and put it back, I need cold start capability as I bet you do as well in Wisconsin.

5W-40 Rotella t6 works great for me.

15w-40 is wayyy too thick.

I might even consider a 0w oil if I lived in briskonsin..

15-40 is for diesels..not recommended for gas engines..bad for cats...but ironically enough its used to break in new engines
