I’ve used only Mobil 1 synthetic oil in the last two vehicles I’ve owned and neither has used a drop of oil between changes. One was a Volvo with turbo which had 104K miles when I disposed of it and the replacement is a GMC pickup with 30K miles.
Engines have been getting better with time, so I can’t attribute it to just the Mobil 1, but I intend to continue using it.

Thank you gentlemen for the comments. I will try the mobil 1 next oil change to see if the mpg changes. I don’t drive the car hard because I am too old for that foolishness. I am however, drooling buckets over that 422 HP Camaro that is about to hit the showrooms. My wife would attempt to beat me if I bought one, but she is old too and less handy with a club.
