2003 Silverado, 5.3 V8, 153K Miles
Awhile back my cousin and I bought 25 qts. of various weights of PU from WM @ $2.50 a qt. (I bought 6 @ 5W30). He has always used PYB and Puro Classic filters since he bought his truck with 19K miles on it.
Well, he is almost 2200 miles into his first ever synthetic OCI. And, it's with some of the PU 5W30. The engine is now leaking oil from the front crank seal/oil pan gasket and the rear main seal.
While he was under the truck surveying the damage, I never knew that he knew such vulgar language!
