I used it in my 2000 Pontiac Grand Prix with the 3.8L engine for 87,000 miles. Worked great for me in the cold Wisconsin winters. I changed it every 5,000 to 6,000 miles.
I am now using the 5W20 in my new Ford and the 5W30 in my wife's Subaru and my son's Nissan. Same change interval as above. All run smooth, quite, and start easy in this very cold winter we are having. I have not done any UOA on any of them as I have not felt the need to do so. I service all my cars as required and my oil changes are well within what I feel this oil will do.
