new member oil recommendation

[sasko]

here is my new truck 2023 GMC Sierra at4 6.2l v8 what oil and filter will you recommend as top natch , what is best of the best ?

 

[john_pifer]

Welcome! Congratulations on the new truck.

Are you looking for the best oil that you can get on the shelf at Walmart or a parts store, or, are you willing to pay a little bit more, and order online?

 

[skyactiv]

Consider Pennzoil Ultra Platinum if you want the "best" without purchasing an unnecessary boutique oil.

 

[PimTac]

Any major brand. There is no best.

The best of the best is "oil" and make sure the engine does not run without "oil".

The main thing is be sure the engine has oil and is changed on a regular basis. I ran an '88 Ford Escort 1.9L to 518K miles over 20+ years on whatever conventional oil that happened to be on sale. The engine was still running with compression numbers 145-155 PSI across all cylinders when I retired the car for other reasons. Sometimes it was a major brand other times it was store branded oil.

Quaker State FS, Pennzoil Platinum, Castrol and Mobil1 if off the shelf. Amsoil, HPL, Redline, or any boutique will do, just change it regularly. Nice truck congrats

 

[Yah-Tah-Hey]

You won't find the answer on this forum sir. Regards

 

[mahanddeem]

Congratulations on the truck. Nice one.
I'd run Mobil1 whatever owner's manual calls for viscosity every 5k miles with OEM filter. Change 1st oil at 1k and enjoy.

Oil is not magic. But clean oil trumps all. Follow the operator’s manual and change often.

Keep in mind that your truck needs 13.3 quarts on each oil change.

What were your change intervals?

It's a 6.2 gasser.

This fits the Dexos1 Gen 3 manufacture recommendation.

"Viscosity Grade
Use SAE 0W-20 viscosity grade engine oil for
the 5.3L and 6.2L V8 engines."


Currently $26.47/5qts.

I personally would go 5k intervals max to try and keep the lifters happy for a long time.

It looks like 8 quarts for the oil and filter change. 13.3 is the cooling system. Funnny, there's no mention of the differential in the capacities chart.

Thanks…

I didn't want to be that guy, but it seemed OK in this case.

 

[userfriendly]

Thanks…

In my opinion, the front and rear diffs come under filled from the factory. Same for the transfer case. Dexos 1 gen 3 is the latest and greatest. GM allows gen 3 to be sold in gen 2 labeled containers for now.

What were your change intervals?

For the first 250K miles or so it got 3K mile OC's which were pretty normal for most cars at the time. After that I went to 5K mile intervals. I worked construction until 2000 so it was driven on and around dusty conditions till 2000 when I got injured and had to go on disability so the engine ingested lots of dust/dirt over the first 350K or so miles. There have been times since I retired it that I've wished I'd have gone ahead and done the work it needed and kept driving it. If I'd have kept driving it I suspect it would have around 650-700K now.
