How much will this thicken up a 5w-20?
I have a very short commute to work and I'm interested in using a 5w-20 in an engine that specs 5w30 because the oil does not get close to operating temp.
The factory fill UOA indicated 9.37 cSt at 1000 miles. The engine seemed to like that a lot better than any of the oils that have followed since. So, could this thicken up a 5w-20 into the lower 30wt range at 1oz/quart? Or would it take 2 oz/quart?
I'm also interested in the additonal adds of course.
