MMM, great idea!

No but it doesn't seem very shear stable, and combined with fuel dilution I see it dropping well below 3.0 in use. If it was shear stable I would be content with 3.2 cP

Buy the next higher grade.

Lakespeed has a video about how choice of gas brand affects piston rings and cylinder wear. His tests showed that choice of gas brand does affect wear.

I wonder if, or how, choice of fuel also affects cleanliness of rings.

Buy the next higher grade.

Unless you live in Australia, there is no higher grade.

There's a thicker grade for my purposes. My neighbors 03 Honda CR-V has been having Maxlife Blend 5w20 go through it like through a goose. I suspect it's burning oil, but I still haven't conclusively diagnosed it. I'm going to put VRP 5w30 in it. For her CR-V 5w30 is a higher grade.

However, I understand what you mean. There's no VRP grade higher than 5w30 in USA.

Grades lower than SAE 30 don't exist to me
