This oil was in service from January until July 2015.
UOA was from a $14 Napa kit.

The only concern I have is the Silicon at 14...thoughts?

Viscosity is all the way up to 11.6

Unheard of for a 5W-30 with that many miles. Impressive.

What kind of air filter do you use?

All good #'s IMO. Even if you have an air filter leak somewhere, it's minor.

I changed it about 2 years ago using a regular Purolator purchased at AA.
I'm going to check for leaks and continue to run it.

With a TBN of 2 do you think this oil would have made 10K? 9K?....how much longer could I have run it?

PS: I think this proves that oil doesn't 'go bad' in storage since this oil is nearly 20 years old...
