changing oil now on my '96 TT with 135k miles and I've always used 10/30 Mobile one full synthetic But as miles are up there now I bought a 12oz bottle of Z Max oil additive. I've seen the infomercials that it soaks into the metal etc. question is, is any additive, MMO, ZMAX, LUCAS etc. any good or is it all just smoke and mirrors? Couple honest opinions before I finish my oil change please.
