What oil is best for 5.7 Hemi?

Engineers aren’t calling shots. Greenies are. 0-30 Amsoil in both of my 5.7s. Easy starts and high temp protection. 20 weight is too thin.

I spoke with a local mechanic regarding 5w20 oil in the 5.7 HEMI. He is highly respected, and also has a radio program where people call in and discuss maintenance, repairs and modifications. His shop has been in the same place since 1988. He said 0w30 will help improve lubrication in the 5.7 HEMI. Most who are using 30 weight oil appear to be using 5w30, though some are using 0w40 as well. 5w20 or 5w30 is going to have the same cold temp viscosity, so either one should be fine. I've heard that all 0w30 oils are synthetic, I'm not sure? Larry said that using 0w30 weight may throw a code, but may not trip the light. A "stealth" indicator, maybe? If you don't know it's there, you can't clear the code. Sneaky!
