I am a firm believer in using one brand and thats Valvoline. I run the high mileage 10w30 in mine and also use Lucas oil stabilizer. I had the upper end clatter and since I have been using this combo it is not an issue anymore. I also have seen better fuel mileage and the engine runs smoother and cooler. And, with the oil stabilizer, the oil stays really clean.

Look for facts. As far as oil is concerned, the best advice you will get here is anecdotal. Go to the website above and learn more about oil than you will ever need to know.

And to answer your question, 5W-30, mobil 1 synthetic with a pure1 purolator filter.

We keep posting it bud but im beginning to think no ones reading it. People freak out when I say 5-20.... I would never run thicker then 5-30 now.
