Just took my oil to get changed on my 2007 Mazda3. The guy told.me synthetic oil would be such a better choice. For $20 more I said no thanks. He said it was a pretty big deal and he'd give me a discount so it wouldn't cost any extra.
So, my car has synthetic oil. my husband is mad, says you can't ever go back to conventional ... any truth to that?
