yeay! another oil thread! Frankly, if you change the oil according the the mftr's recommended interval, dino oil works just fine. I use Castrol GTX. NAPA gold for oil filter. Are they the best? Prolly not. But, they work just as well at half the price. oil changed every 3 mos. or 5000km (~3000miles), whichever comes first.
In my 25 years driving cars and racing motorcycles, what we have found out is changing the oil on a regular basis is more important than the brand or type (syn or dino). I change mine every 5000 miles or every 6 mo. if you drive less than 10,000 miles /yr. Oil is more important if you have a diesel engined vehicle. My V10 Touareg I change every 5000 miles with special diesel synthetic oil @ $9/qt. Ouch !, and it holds 13 qts of oil.
I have always heard good things about Pennzoil Platnium synthetic. It's a true class IV syn oil where as mobil1 is a class III. I have always used Purolater Pure one filters. They are some of the best on the market. Check out www.bobistheoilguy.com for some great reading and reviews on oil and filters.
