oil recommendation for GM 5.3L trucks

[hardheaded]

0-20 or 5-30 for 15 and 17 chevy 5.3 trucks ? How about the 5-30 in my 11 tahoe ? Should i step up and use 10-40 in it ?
This use to be so easy back in the old days. Thanks for the opinions !

5w30 if you want to keep life simple. or read the above and enjoy the ride.

You mean this didn't have to replicate, duplicate and regurgitate as yet another thick vs. thin thread?

0/5w-40 isn't much more than 5w-30. I use 5w-40 in my 2021 6.2. 10w-40 is ok but not amazing. You can buy warren made mag 1 10w-30 for 2.79 a quart so 10 quarts is 28 bucks with free shipping. I buy the thicker mag1 15w-40 for my old high mileage trucks with have over 600k combined with original internals so I feel like using thicker still.

5W-30

5w-30 is going into my ‘16 Suburban next month, just deciding if I want to go with:

HPL NoVII 5w-30 (I like the 3.399 hths)
HPL PPPCMO 5w-30
HPL PPCMO 5w-30
or
Amsoil SS 5w-30 (I have on the shelf)

whichever I chose I will run the full OLM for my changes.

If your not having consumption problems with what your using, why change now?. My '11 chevy equinox will use a qt of 5w30 every 750 miles. I bumped it up to 10w40, and now it uses a qt every 1500 miles. I can live with that, or I can spend the money and rebuild the engine. If it wasn't using so much oil , I would still run 5w30 in it.,,

I see your HPL NoVII has a HTHS number of 3.3399, my Mobil 1 ESP 5W-30 has a number of 3.5
When I run out of my Mobil 1 ESP 5W-30 for my vehicle I might try this oil, so far, I am having good results with HPL CK-4 10W-40 in my Riding Lawn Mower.

No VII Euro 5w30 has an HT/HS of 3.566 and is certainly fine to use in LS engines without worry.

I forgot that the HPL VII Euro had a different HTHS Number versus the HPL PCMO VII Oil
It is not fair to compare a Euro spec oil to the Watered-Down spec oils, let's be realistic, the only speck oil we have that can compare to the Euro Spec oils are the CK-4 spec oils. JMO

5W-30 across the board keep in simple

5W-30 across the board keep in simple

I tow up 9,000 foot mountain passes in 90 degree heat with my 2023 Silverado-5.3. The manual calls for 0W/20. That's what it gets.

that's good

OP also has an older vehicle that calls for 5w-30

 

[ripcord]

Use a dexos approved oil with of viscosity between 0w-20 and 5W-40. Change it between 5k and 10k miles or once a year. Nuff said.

 

[hardheaded]

The 15 and 17 call for 0-20. I think that is just thin for my liking. I think i will bump them up to 5-30 or 10 40. I may do the same with the 11 which calls for 5-30, bump it to 10-40. I don't think it will cause any harm with the AFM system.

5w30 Kirkland all day. Load up and never think twice

 

[userfriendly]

Unless you’re going to run a conventional 10w40, there aren’t many synthetic choices out there at reasonable prices.
With all the hoopla about the 6.2L running on 0w20, the Dexos approved 0W40 seems like a logical choice for all 2014 and newer GM V8s.

 

[xmanjeff]

i have a 03 silverado with a 5.3 , its gotton 5w30 all a long , doesnt use a drop , it currently has 10w30, i got a bunch from a walmart clearanc for 5$ a jug , mine is a simple engine , newer than that is more complicated , but i just cant see how a 5w30 or 0w40 would hurt things in your engine

 

[zfasts03]

Amsoil 5w-30 sig.series went in the 16 Suburban today as I already had it on the shelf.

Maybe HPL next time!
