Comments about Marvel Mystery Oil® Top Cylinder Lubrication:
Ive been using marvel mystery oil for the last few years in 3 different cars and in small lawn equipment engines with great results. I use it in gas and oil. In gas you only mix 4oz to 10 gallons so a bottle goes a long way. It PAYS FOR itself because I usually get a 2-3 MPG INCREASE. I also noticed that it makes lawn equipment and car exhaust fumes smell MUCH less. In Oil it cleans the engine and makes starting better/quicker in the winter. I definitely recommend this product. It's been around a long time and works. You'll save money and your engine(s) will work better!
