Havoline 0W20 VI higher than 5w30 and 10w30? #5142752

I was looking at the spec sheet for Havoline synthetic oils and the 0w20 has a higher VI than all the other oils listed. Do you reckon this must be a misprint?

No. The 0W is thicker at KV100.

You can calculate VI yourself to verify.

No, I "reckon" it is correct. Why would you think it is not?

Mobil 1 0W-20 is published as 173, well in the same range.

Okay I guess I don't understand VI then.

No. Simply, viscosity index means the finished oil flows well at low temperature, and doesn't lose viscosity dramatically at operating temperature.

For comparison, Mobil 1 0w-20 AFE's viscosity index is 173, 5w-30 is 172, and 10w-30 is 146.

Okay, so it isn't saying that it is thicker than the others at operating temperature?

Not at all. Viscosity index is a dimensionless number that represents how the viscosity of lubricant changes with temperature. The greater the viscosity index (VI), the smaller the change in fluid viscosity for a given change in temperature, and vice versa. Thus, a fluid with a low viscosity index will experience a relatively large swing in viscosity as temperatures change. High-VI fluids, in contrast, are less affected by temperature changes.

For people in warmer climates, wouldn't a lower VI be a good thing? To an extent of course.

It seems like most high VI oils are loaded with VII and are less shear-stable.

Maybe this chart can help you understand: at 40c all the oils are the same viscosity, but as the temperature increases the oils with a lower VI lose their viscosity at a more significant rate in comparison to the oils with a higher VI.

That, or they are blended with extremely thick and thin base oil (synthetic) and the volatility is high, leads them burnt off / evaporate away. I'd try to use 10w30 and 5w20 instead of 5w30 and 0w20 whenever possible.

Or it benefits (just as a published number) from low cold flow ability - and that does not mean much to me even though I own two 0w20 spec engines …
I could spend $50 gallon to get a really high VI 0w20 - but that's not going to protect my 7500 watt gen better than 15w40 at $12 gallon (would have much lower VI)

iirc TGMO 0w20 was 200+ VI

You would want to look at HTHS viscosity. It represents how a fluid flows in the engine parts at high temperatures. A less useful but highly published number is KV100, or how an oil flows at 100C aided by gravity alone.

Guess you are too fancy and sophisticated to like the word "reckon".... LOL

Yes, I think so, assuming it’s well made.
I’m running a full Group III synthetic 10W30 right now, and it offers me all the winter cold starting ability I will ever need, but more shear stable and lower noack volatility than an equivalent 5W30.
