API - American Petroleum Institute
Increased acidity levels cause damage to all internals, but eat at catalyst media more. The longer an elevated acidic oil/solution is present the more degradation it causes. If you have a 60 it should have a catalyst system per federal regs. But that's for another discussion.
I've never tan 20/50 in a 2F or similar, especially in a cold weather climate.
But the most comprehensive " high content" zinc oils the early motors need..

Did you leave it in long enough?I can verify it doesn't work.

Your Mom axed me the same thing !
With the amount of make up oil I add on a regular basis, I never need to change it. It's always semi-fresh!yalls 2fs keep oil in it long enough to worry about the oil???

Amsoil is not API certified, refuses to meet API standards and testing.
Phosphorus levels are 5-25% higher than API standards.
Phosphorus is a main anti wear additive for all oil mfgs, but at the increased levels that Amsoil uses it increases the acid level in the oiling system and causes exhaust degradation to the catalyst system. Don't get me started on the cost to replace these components these days.
High performance engines that get rebuilt after every 1-4 passes for a quarter mile run are one thing. There is not a single NASCAR, Indy, or any other longevity required engine that uses Amsoil. Never seen a Amsoil sticker sponsoring on any of these.
Snake oil at best.
