My 1992 Geo Prizm (Toyota Corolla) with 249k miles on it has a 13.5 gallong fuel tank. I added 3oz of MMO during may last fill up at Kroger (sorry, but the 10 cent discount seals the deal).
MPG before: 33.7
MPG with MMO: 36.8
The only two things I did in the middle of this last tank is add 16oz MMO to the crankcase along with changing the oil from PYB to PHM, and I got my AC working again and have been using it off and on during the past week.
I added another 3oz along with this fuel fill-up I did this morning. I will report back.
The car runs noticably better also. It seems as if the engine is eager to just keep accelerating now. I'm anxious to see the difference the MMO makes under the valve cover too. I am leaving it in for the entire 3k OCI but I will change the oil filter half way through.
