No problem Ram2K1, I did get enough info, also got a headache from reading various web sites about oil and filters. I found out that unless you are in a cold climate, which I am, that syn oil is best used in hi-po engines. I am still going to try the mobil one high mileage and then go from there. I had been using the napa gold filters(used to be a fram user) but after some more reading it seems that there are some better filters out there. I think I have done too much reading so that everything is as clear as mud now, LOL.
