Just what it says. PP claimes to have superior cleaning power but which group III has better cleaning additives?
Amsoil XL or PP which has more cleaning power?

From looking at the VOA's and UOA's PP has more detergents.
The TBN is close to the same on both at around 9.
They are about the same, but looking at the UOA's and knowing a few things, I say Amsoil XL. Most guys are just piling on with PP by counting only Ca. But there is more to an oil than what shows in a VOA/UOA - and no oil is a cleaner alone.
