A week ago, my friend installed Castrol Syntec in his Mazda 6, ran the oil for 3 hundred miles, and felt like he hated the oil, so he drains it, pours it back into the 5 qt jug and returned it at Advance Auto where he purchased it. He told them he wasn't happy with the product and they took it back. LOL
Then he buys M1 and puts that back in. Should have stuck with the Syntec from what I've been reading lately, huh?
