Not only that, but the standard for synthetic oil has been lowered. To get the good stuff, look for the word “ester” on the label. If you don’t see it, the oil may be the cheaper stuff.
And there’s no standard for % in semi-syn or synthetic blend. Could be as little as 10%.
It may be a pig, but it's a pig with a rocket in it's ass!
