Supertech vs. Syntec (O'Reilly)

[Urshurak776]

I bought a jug of M1 5W30 (Dexox 1 Gen 3) for $24 and an Asian made Microgard Select oil filter for $9, for my next oil change.

Same, plus there was an $8 rebate on the Mobil 1. Got it in less than 10 days. Used an OEM filter I get for about $5.50 in bulk. So , $33 for store brand oil and filter seems high to me. YMMV.

In all of my old GM vehicles i get a noisy- piston slap- startup with a 5w30 that is not there with a 10w30. I run a 10w in them year round in PA w no issues, synthetic or blend or dino never mattered

I wonder how O'Reilly is able to use the Syntec name without getting sued by BP? I'm guessing the trademark expired since Castrol no longer has that name on their labels.

Did Castro drop the patent to that name?

Looks like Castrol sold the name (trademark) to O'Reilly.
