I bought three oil changes worth. (18 quarts). $36 plus tax. Pretty sweet deal. Now I must decide if I too, have the nerve to run it super long, and in what car. It's either going in the 2008 Santa Fe with a 3.3, or a 2005 Ford Freestyle with a 3.0 Duratec. Not sure if I have the stones to run it a year at a time. The Santa Fe could do 20k in a year, the Freestyle only 12k-15k. I only paid $350 for the Freestyle, I'll probably test it out on that! The Santa Fe has only gotten Valvoline Synthetic Maxlife for a long time. Don't know if I'm willing to change. It consumed 1/2 quart in 5k on Mobil 1, it doesn't burn a single molecule on the Valvoline. I know 1/2 quart over 5k is very little but still.
Santa Fe has 205,000, Freestyle has 292,000.
