2015 Yukon 5.3L 0w20

[pjmbull]

Wanted to get the various opinions of the BITOG universe....I have a 2015 GMC Yukon 5.3L that calls for 0w20. All of my other vehicles (all GM) call for 5w30. For simplicity I would like to run 5w30 in all of them, but wanted to ask about the Yukon. Would it be a problem if I ran 5w30 in it? I live in Maryland so we are a 4 season state. Can get pretty hot in the summer and can get pretty cold in the winter. Would 5w30 cause any issues for this engine? Can this engine manage with 5w30 or is 0w20 a must and should not be deviated from? Thanks.

 

[Oillover]

Use 5w30 with confidence.

 

[cptbarkey]

Sigh.

 

[pbm]

5w30 should be fine for that engine in your location.

Sigh.

You live in Maryland, if you lived at the North Pole, then I would say 0W-20. I will say this, and let me jump in and say, your engine will like 5w30 in the long run better than 0W-20!

Would 5w30 cause any issues = No, in fact may live longer.

[Brian123]

If your car calls for 0W-20 and you really want to stick with a 0W Oil, just go with 0W-30, that way you can be Thin and Thick!

 

[ATex7239]

Sigh.

But what is the best oil for my engine?

 

[DFWoilguy]

My recomendation:

Castrol GTX Full Synthetic/Edge, Pennzoil ultra platinum/platinum, Valvoline Full Synthetic 5w30
If you got the $$$ and like to do Long OCI's HPL, Amsoil

Would stay away from M1 AFS, the current formula is week unless you do 5K OCI's

Please give a technical reason as to why it is “week”.

And what is “AFS”?

AFS is a acronym for Advanced Full Synthetic" that's labeled on Mobil 1. Not playing your sadistic "Games" bud, find someone else to "Play with"

For everyone else:
Lots of "papers", used oil analysis and info on BITGO/ Youtube/Blackstone lab reports to answer this question on why Mobil 1 AFS is "weak" compared to older formula

And for the record I'm ONLY mentioning this about Mobil 1 "Vanilla" AFS!!
*NOT Mobil 1 Euro, Mobil 1 Advanced Fuel Economy, Mobil 1 ESP, Mobil 1 day and night flue cold formula, Mobil 1 extended performance or Mobil 1 Truck/SUV

Pretty much the non-answer I expected. Not one shred of objective evidence. UOA, "papers" and YouTube videos are a dismal source of comparative oil quality.

I would not agree that it's weak. I would agree it's different. As are many of their products; they differentiate them with slight formula changes to meet the goals of the target market. I think your assertion is, in itself, weak; you've done nothing to prove your claim other than to regurgitate some baseless talking points.

If you have merit to your claim, than please give specific, credible examples as to where this oil is weak relative to the market it's placed in. What makes it "weak"? Vis? HTHS? add-pack? How does it stack up against other brands in the same marketplace? I hope you realize that not all additives will show up in oil analysis; hence, you can't fairly claim that something is "weak" just because it's different.

It's easy to fling some tainted jabs over the internet, but can you back them up with real hard data? I'm not saying you're wrong. I'm saying you've done nothing to prove you're right.

i maintain a fleet of GM vehicles and have quite a few of the 5.3L half tons calling for 0w-20. 5w30 goes in them from the first oil change. use with confidence that you are more than likely helping the engine life a easier life.

Sir, I'm going by what I have read and heard(including Blackstone lab reports) I personally do not use M1 products on any of my vehicles and don't really ever plan to since the "sheeples" always demand it and it's my #1 selling product lol


1.When I was doing my sales, I stopped by a well known Porsche/German car shop in DFW owner saying they were having "heat issues" running M1 on a clients 996 and when they switched to Motul/Liqui-Molly the "heat issues" went away??? It was a quick stop and this was 2 years ago, so next time I'm around there I will ask him for more info on the M1 issues they had

2. I've had few of my clients tell me they had "engine noise" running M1 new triple action formula and also have read MANY online reviews on WM.com and Amazon about M1 "Vanilla" and many common complaints/reports of a "engine noise" and a "louder engine" when they switched to M1 and then going away once they switched back to original oil brand they had been running or a different brand??? Anyone is welcomed to go through all of those reviews like I did

3. Anyone is free to watch FORDBOSSME (Ford ASE tech) on YT and watch/listen to his Blackstone lab reviews on many oil including M1 and his explanation of why it's a "weak formula" I'm sure all of us can respect Blackstone labs and not much the guy on that channel who comes off very obnoxious and arrogant lol...................Must be a "Midwest attitude" thing ??

4. LSJR I believe made some negative comments about "plain jane M1" but will have to dig for that one and post it on here

Don't get me wrong seems like a good 3K-5K oil for most of us. But thankfully there's MUCH better oil options out there in today's market
