    I would suggest oil that meets the manufacturers specs, and nothing else.

    If it's not in the owners manual, what would make you think an aftermarket company seeking to make money from you would be telling you the truth?

    May I answer it this way? Chevy or Ford, Volvo or Subaru? I think most will say Lucas is better, but then some will not agree. I would suggest Lucas as your better choice.
