I usually ignore commercials on TV, but I happened to catch the fine print on the latest Quaker State "Q Horsepower" ad...it states: "Ferrari recommends Q Horsepower 5W-40 and 10W-60 for its cars". I'm just wondering if Dr. Haas would care to comment as he's stated here that he runs 5W-20 in his.
BTW, this isn't a challenge; I respect his contributions to this forum and I'm truly interested in what he has to say.
