This stuff is great

I love what this stuff does, even for newer engines. Saw reduced smoke and oil consumption in my old big block and made the wife car run a lot smoother. As long as the seals aren't rotten it should recondition them back to functional.
Exactly what I expected - been using it for years

I've used MMO for a while and it's really great keeping carbon buildup down on my boat (which is a chronic problem for my model) and I use it in my car which is seven years old. You can tell the difference after a bottle (3 tank fulls) as it's peppier and about 1.5 miles per gallon better mileage. Also car and boat engine are quieter. I don't use it all he time in the car. Just treat 3-4 successive fill ups every three months. I use it in the boat every fill up.
