Castrol And Fram

My dad - who worked on everything from jet engines on down… used pretty much anything. It shames me to say and to speak ill of the dead… but Pop was an oil slob. Any mid grade oils would do; he didn’t give a chit! Same way with oil filters too. With two cycle machines he’d use 4 stroke oil to mix with the gas and dammit - I started doing it too…

But unlike Dad - I repented of my sins and became a morally pure-as-the-driven-snow Castrol man! My oil filters are all Fram. That was 20 years ago when I saw a third party study and those two came out tops. I wonder… is that still the case today?

Might be worth a deep dive investigation, maybe. 20 years is a loooong time.
