use of 40wt oil will provide superior protection to a 30wt oil at elevated temperatures. I have met a few people at the track who do not use the proper oil in their LT1s as in they are using 5W30 so this will likely fix that issue too. |

Can I ask why you wouldn't run a catch can? This will alleviate your PCV concerns and I suggest all GM DI engines should have some sort of catch can setup to maintain intake tract and valve cleanliness (I run a Mighty Mouse on my Denali 6.2).

I honestly believe that the only reason that CCs are not OEM is the fact that if someone neglects to dump their CC, all that goop in the can will be ingested into the top end and that could prove to be catastrophic. It's possible that the legal team does not like the potential for liability. Sorry OP for drifting off topic.

Sorry as well for the derail, good oil info in this thread, just thought the CC was a good topic to add to the ash issue brought up. Thanks for the replies

Does this apply to CANADAIAN cars, because according to my dealer it doesn’t and I won’t be coevered under warranty if I switch oils and have an issue.

Sounds like a lazy service department who doesn't want to have to look up any information or bring in oil they might not yet carry...

What’s the big deal about dexos?

Short answer: If you own a 2011 or newer GM vehicle, you must use a motor oil that meets GM’s dexos specifications to maintain that vehicle’s warranty.
From what I understand, Dexos 2 greatly reduces the byproducts of GDI/PCV especially when associated with forced induction. Notably, coking of intake valves and guides, as well as varnishing intake ports and charge air coolers (blower bricks). Dexos 2 also protects the guts of your cats from premature clogging and wear. My $0.02. For what it's worth.

The stamp simply means the oil company paid GM to have it on their bottle. Yes, there are some standards that must be met......but there are tons of great oils that would meet the standards, but haven’t paid for the stamp.
It’s either a BS scam, or brilliant money making and marketing idea. You decide. |

I have a supply of Valvoline 5w40 ready for my next couple oil changes, yet the 5w40 part of the question was omitted. Guess it's fine since it's Dexos 2.

Dexos 2 5w40 is fine to use all the time.
Edit. The fill cap on a 2019 Z06 Vette says 0W40. Saw it in person. |
