5w-40 oil in the ZL1
Thinking about switching to Royal Purple SAE 5W-40 High Performance Synthetic Motor Oil for my next oil change. They have a 0w-40 but it does not have the Synerlec additive. The 5W-40 does. They also have the HPS oil in 10w-40 with the zinc / phosphorus package.
Pros / cons? https://royalpurpledirect.com/royal-...tic-motor-oil/ |

I would use the weight the owners manual recommends just to be safe for your engine!

Royal Purple is probably the last synthetic I would pick
Castrol Edge, Amsoil, Mobil 1 EP (not th standard stuff) all fare well in standardized tests. |

For competitive driving the 2017 and 2018 manual states to use 0W-40 or 5W-40. For 2019s and up models GM recommends 0W-40 in general for the LT4.
It is now also factory fill for LT4 Corvettes etc. So why not use the better oil.

My owners manual says SAE 5W-30 and also has it on the filler cap, so that's what I use. There are plenty of oil threads on here, so to each their own.

While I doubt any issues will come up with 5-weight, I believe GM did say they recommend the 0W over the 5W (excepting the ZLE) from earlier models, but it's just a sematic I think. 5W is just a little thicker in the cold, and I don't drive mine in the cold, so it doesn't matter too much to me. I'm more concerned with the Dexo 2 certification.
