Q for those who uoa dino

[jorton]

If I'm really lucky we can get a brand to repeat.

Have you tested an api SM 5w-30 or 10w-30 that stayed in grade?

I had good luck with a 5k run of Valvoline 5w-30.

All UOA's I've done have stayed in grade aside from Havoline DS, which starts as a low viscosity to begin with.

MadAmos' Castrol GTX 10w-30 did well.

Valvoline Maxlife uoa shows the benefits high mileage oil provides. Viscosity is 30 grade.

Don't need a major brand name to get a durable 30 grade.
