well, i hav gone past that... 3 yrs, 2 mos & 2 days going 23,671 miles... had it tested, only lost a little viscosity... use in ALL my vehicles, & sell occasionally... absolutely exceptional products...
I use Amsoil signature series. On another channel I watch the guy sent in Red line oil after 5000 miles and it did far better than the Amsoil after 5000 miles. I’m thinking about switching. But I’m sure either one would be fine.
I've never had it tested, but have used it for over a year on different vehicles. The oil has never been overly dirty or had any indication of breakdown. And I've never come close to their 25k mile range that the oil can last.
Great stuff! My oil analysis comes back spotless with Amsoil
Indeed the 1st in synthetic oils.
That oil looked really good imo

Exactly, I even use their Z-rod in my 70 Vette! All vehicles should use it whenever possible, fully agree.

Red line is good stuff too, I've tried some of their products.
How was the viscosity of the oil after 1 year?
