In the past, going back to 1990, a Dodge van, a Ford van, a Saturn I4, a DaeWoo I4, A KIA I4, a Mitsubishi I4, a Pontiac van, a Sunfire I4, a Neon I4, a Corsica V6, a Baretta I4, a Pontiac Grand AM I4, a VW Fox I4, a Camaro v8. Seems like there were some others but at 10:30 I don't remember so well and I am to lazy to look up records. These are for me, my wife, oldest daughter and husband, youngest daughter and husband. If we go after nephews, nieces, brother in laws, sister in laws, and converted neighbors, it is even more.
I have an average figure somewhere, even on a thread here. Again, to lazy/tired/old/late to look it up but the average mileage at trade in was in the 180,000 mile range. every vehicle got better than EPA mileage estimates but that is no big deal. After reading the API site more carefully, the average driver may not notice any difference between a 0W-20 and a 20W-50, so I wouldn't be impressed with mileage. What impresses me is never a leak, never a seep, no consumption, no engine noises, never an engine problem, and an engine with 301,000 miles that reads compression values with speck of a new engine in all 4 cyls, and with a total spread of 8 pounds.
I have no brand loyalty, none. If I find something tomorrow that I honestly believe is better, I will convert at next OCI. I am confident of the ad pack, the base oils, the 100c cSt(low at 18.1) the HTHS(again, not so thick at 4.5) the all around oil.
Understand that this is a personal opinion, but, a personal opinion based upon over 2,000,000 miles of use on many different vehicles, drivers, and geography.
Certainly impressive results! I also think it could be that FrankN4 lives in a warmer climate and the oil could be a better match for him than some of our friends in Canada, or other cold places in the USA, especially during the winter months.
My father had several quarts of the red cap version of Mobil 1 15W-50. He would use it during the summer adding a quart to 4 qts of 5W-30 and used it up that way. JMO
