I am with ya Scott, My VX started using more oil about 7000 miles ago it went from a quart 1000 to 1500 mile to a quart 300 to 700 miles. I figure that maybe if I add MMO now maybe I get it clean before it goes to long. I am the second owner of this car. Bought it with 56000 miles it now has 69000 miles on it. I honestly think that MMO would be not as harsh as some other engine cleaners out there. If it works I'm happy happy happy! if not I will run it till it blows. Just gotta try something
