Kirkland Signature 0W-20 Full Synthetic Motor Oil

Mr.IMAPCMD · April 18, 2023

Anyone have any experience, good or bad, with using Kirkland Signature 0W-20 Full Synthetic Motor Oil? Costco has it for $63.99 (4-5qt bottles) right now.

Thanks

This oil is probably OK, but the current GM spec is Dexos 1, Gen 3. Gen 2 is now obsolete.

Before he mentioned it, I was thinking that the results show near identical characteristics and probably indicate that they are the same oil packaged in different bottles. I would like to see how they compare to some of the more name brand oils and see if there is a significant difference in detergents, wear, etc., or not.

Great Video.

It's on the list.

I've never heard anything bad about Kirkland oil.

Yea I think Warren? They do a lot of the private label I think even Amazon Basics oils.

Thanks everyone. Just ordered online since the local stores do not stock it.

I do enjoy those Project Farm videos. He's a fast talker. Some might use the term motormouth. Perhaps all that oil cooking contributes to the fluidity of his presentations.

Yes Warren oil and the last few bottles I have are Dexos1 Gen3.

Dexos2 is diesel oil for the 2.8L

DexosD is diesel oil for the 3.0L

The 6.6 Dmax uses the same ccd/CD oils as other large diesesl

DEXOS 1 (gen1, then gen 2 and now gen3) are the gasoline engine ones.

Kirkland pic in the first post appears to be Dexos2 -- which is not spec'd for any engine used in the 1500 or 2500/3500.

Dexos2 would be for the 2.8Lwas used in the Colorado/Canyon twins.

Current list of oils that meet the various Dexos specs can be found at:

Kirkland and ST are both the same, Warren made.

Took my '99 Yukon to 210k miles on it, a '09 Malibu to 220k on it and most recent a '11 Tahoe to 150k with zero oil related problems. All the above sold or traded running fine. I use either one, price determines it. Just stocked up on some Kirkland while it's on sale as I've got 3 3.6 motors to maintain as well as the 6.2.

@repairman54 how often do you change oil? Just curious. You have a good track record.

Dexos2 also covers Euro gas engines and until the DexosR came about, covered Camaro and Corvette 2019-2023.
