Can you elaborate?What about DI deposits?
You may be using it in an in-warranty application, but that doesn't mean everyone else should have the same comfort level.
If I needed a 20 grade oil, then HPL 10W20 would be at the top of my list. The idea of a full synthetic (Group IV & V), shear free monograde with a modern additive package has a lot of appeal to me.
A 10Wx oil is good down to 0F (-20c) for cold starting, which would also be enough for me.
Yes, I believe it is a Group III with AN and ester.Good point, and thanks for clarifying, so as not to confuse others. I was more saying it does contain the higher Groups, which many budget synthetics do not.
BTW Group III and GTL base stock only comes in thinner viscosities such a 2, 4, and 6 cSt (KV100). The HPL 10W20 has a KV100 = 8.62 cSt, and with no VII polymer to thicken it up, it needs some of the higher Groups (IV / V) present.
