Chevron Supreme and Dexos.

[SigShooter]

I bought a 2011 Chevy Silverado in March. I changed the oil about 3500 miles ago using Pennzoil Platinum 5w30. I have 6 quarts of Chevron Supreme 5w30 that I would like to use. Would it really hurt to use a oil that is not Dexos certified for one oil change? Thanks

It will only hurt your warranty.

No. It and you will not know the difference.

Unless it's really old chevron supreme. I not sure if they made Api SJ or such. Sm or sn the engine won't know .

Unless there is a very mean GM mechanic hiding in your garage as he watches you put in the oil, you will be fine, and so will your truck.

I wouldn't take the chance since it seems almost all Dexos oil is a synthetic blend.

Doesn't your truck have an OLM? What interval does it usually suggest?

The Chevron should be OK for one OCI. But don't do it again

Walmart has a great deal on Pennzoil Dexos Blend for like $17 a jug.

Whelp, the Silverado is not turbo, and Chevron Supreme is an excellent oil. I personally would not think twice.

go for it. it won't hurt anything. GM has no way of proving that what is in your sump is not Dexos 1 approved.

Would he not need to provide documentation(receipts) to the dealership showing he did his own oil changes if there ever is a warranty claim? If they see that a non-approved oil was used, wont they then deny the claim? I'm honestly not sure, I am just asking, I have not had a chance to buy a vehicle in warranty yet lol.

Just keep a service log and write down the oil as Havoline Synthetic Blend (Dexos approved). It's a Chevron oil with a similar additive chemistry.

Chevron Oil- Been using it now for a few OCI's. Very impressed by this oil. It's totally quieted the HLA clateer that many Miata's have. Use it!!!
