I was at Wally World browsing the motor oils. I was looking at what other 5W20 oils for the Escape. I'm using the Magnatec on my first change that I have on hand.
I noticed on the Castrol EDGE 5W20 it has the A1/B1 spec plus GF-5 and the other GM and Ford specs it meets.
The Magnatec does not list the A1/B1 nor does M1 5w20.
Is the A/B1 a 'better' more stout spec?
