As you can see from the list, some 5-30w oils are approved. I prefer 0-40w or 5-40w myself, (synthetic) result of the high revving WOT life mine leads in my hands. The paper filter isn't as good as the fleece but as long as you don't extend the change interval it's "good enough". The fleece should be used for extended oil change intervals. Being a Crossfire for life man, I use the fleece filter and change my oil twice a year no matter what, have it analyzed, yada yada ya, etc. IMO, even if they used the worst oil on the market, you "should" be OK for 3000 miles. I'm old enough to have used non detergent oil and the cheapest filters available in cars and they lasted over 100,000 miles. Now that your nerves are settled, be smart and use the best you can afford. Mobil 1 0-40w has been proven to be one of the best weights made by Mobil, well, from what I've read and seen from my Blackstone reports. We all want to use the best at all times unless the expense is unreasonable. Over the years I've learned some things and one of them is to trust the engineers of the car you have. They didn't read other peoples opinions on some forum. They tested, tested and tested to come up with recommendations and know more than we'll ever know.
