Anyone running non DEXOS oil in older GM?

[53' Stude]

Brother is running a non DEXOS oil in his 10’ Yukon Denali without issue. Soon he will be using either M1 0w30 or TOTAL 5w40. Always uses older yellow grip Purolator 1 filter. Any of you folks use non DEXOS oil in your older GM vehicles?

Thank You

Which dexos license are you referring to exactly? Depending on which one there are definitely some European approvals that have similar requirements. dexos isn't unique in what it requires.

Here are few existing threads on the subject that may be of interest:

if it has over 75k probably a 5w-30 synthetic high milage formula would be fine to use. also most hm oils are not dexos rated,in this case it really does not matter either way.

DEXOS 1 GEN 2

Yeah bro never was a DEXOS fan. For while he was running DELVAC ESP 1 5w40 I gave him

DEXOS 1 GEN 2

d1G2 is very close to what API SP requires. It was primarily concerned with LSPI prevention.

At least he doesn't have to worry about warranty! I'm the opposite, I have so much Dexos 1 oil around from closeouts it goes in everything (except the diesel, of course). Nothing in a '10 Yukon is going to be hurt by non-Dexos anyhow.

I ran Valvoline Maxlife HM for years in my 2005 Chevy 5.3. IIRC it wasn’t Dexos approved. I sold it at 248,000 miles. The Valvoline ‘Restore and Protect’ I believe is not Dexos approved. I’m running the R&P in my 2019 Chevy 4.3.

dexos didn't start until 2011, so 2010 just makes it

I didn’t know this

Adam, regardless that’s good oil he was using. If he’s changing it regularly and not extending the change intervals he’s fine.

while there is no need for it in mine either (2005 GMC Yukon Denali - 6.0) I find that most any oil I choose to use has the Dexos 1 Gen 2 and now Gen 3 approval...during my ownership mine has had ACD, Farm and Fleet and now Quaker State full synthetic motor oils in the recommended 5W-30 and the Dexos 1 approval...

I never understood those that let a Dexos approval dissuade them from buying a motor oil...buy whatever meets the approvals and recommendations for your particular application and go from there...

anyway...good luck with your choice

i run non dexos approved oils in brand new Gm engines. EP HM oils, HPL oils etc.

Non-Dexos is just as good to run there. If consumption worsens, thicken the viscosity.
