Which NO-VII Oil would you recommend?
- Thread starter rwn
- Start date
Any oil with a 5W winter rating will perform better in cold than any oil with a 10W rating. Unless of course, the blender or formulator is labeling the product contrary to SAE requirements.
That’s what the winter rating is for.
That’s what the winter rating is for.
Does the Cold Cranking Simulator and MRV Viscosity above corroborate that?
Why do you want a no VII oil?
What operating condition are you trying to address?
Why would you ask a group of folks on the internet, instead of the maker of the oil?

Should all questions be directed to the manufacturer what's the purpose of this site.
One of the functions of this site is education - one of the conditions of this site is avoiding trolling.
So far, the advice is specious, but not as specious as the questions.
When the manufacturer has a PCMO that meets viscosity and specification requirements, is extraordinarily shear stable, and has been shown to last for 30,000 miles in service without viscosity breakdown, then why does this brand new user, on his first post, ask specifically about a NO VII?
While ignoring the painfully obvious - the 5W will “perform better in the cold” - whatever that means.
There is a lot about the question itself that doesn’t make sense. So, I asked questions for clarification, which is needed before I can give a reasonable recommendation. Plain and simple.

All we need to know is his coldest start up temp what version of the oil is up to him. I run the NO VII I didn't think I needed a special pass to run it meets the spec and that's my decision I made.
You have been here for a few years and have 3,500 posts.
Was your first post one that started a new thread, one with odd technical boundaries and conditions?
I picked NO-VII because of the Dexos1 gen3 rating for my GM 5.3 pickup.
Wintertime Colorado high mountain conditions.
I asked HPL using their website contact inquiry form but never received a response.
Now, I understand a bit more, as a skier, too…
So, that extra detail, “I want a D1G3 rated oil” is important context for your question. Because you’re asking about oils that do not meet the D1G3 on the basis of their viscosity, even though the text on the page says that they meet the performance requirements.
With that - let’s reach out to @High Performance Lubricants - and ask, “do all the PCMOs meet Dexos 1, Gen 3 performance specifications?”
Because that is what is implied, here: https://www.advlubrication.com/collections/automotive-lubricants/products/no-vii-engine-oils
“Although the viscosity specifications do not align with the below specifications, the PCMO and Euro series both use additive chemistry common in the below performance specifications:
PCMO Series is a suitable replacement for: API SP, dexos1™ Gen3, ILSAC GF-6A, Chrysler MS6395, Ford WSS-M2C945-B1, Ford WSS-M2C946-B1.
Euro Series is a suitable replacement for: VW 502 00/505 00, Porsche A40, ACEA A3/B4, API SL, Daimler MB 229.3/229.5, Renault RN0700/0710, Volvo 95200356”
Let’s see what they say, because if the PCMO meets it, then you have a lot more options, including better cold weather options, than the NO VII series. The gen 2 to gen 3 shift was mostly oxidative resistance, I think, and if one of the HPL PCMO meets it, pretty good bet that they all do.

I run the No-VII oil in 2 of my vehicles. It gets down to 10-15f here, rarely 0f. If i was in conditions of -15f. I would want some VII, in a 0W-xx oil.
I don't run the No VII in my ram, as it would be a 10w-40, and i want good oil flow to the lifters during cold weather, in this engine.
That's just my opinion. It's worth what you paid for it.
In my mind, achieving specifications without additives is superior to adding the polymers to achieve a result. So I think better/varied base oils to achieve a result without additional additives is a worthy goal. Now if you couple this with cost the scenario does shift. As the mantra of the board is, minimum cost oil for the maximum interval that doesn't diminish the protection of an engine is the best possible outcome. My bias may not be your bias. So in keeping with the sites credo, the cheapest oil that does the job. So whatever is on that list that costs the least and protects to a minimum measurable standard should be the choice. Not my choice, but I am biased.

the good old regular PCEO is Dexos 1 gen II. i just posted a UOA from a 5.3L LT silverado over 11.7k miles. results are stellar with the engine showing extremely low wear.
