Oil Additive, 1Gal, Red, Transparent

First off, I am amazed at the speed of delivery. Was initially estimated to arrive between March 1-5. I got it on February 26. I tried it in my car and it seemed to run quieter, not that it was loud. When using my snowblower this year it was backfiring a couple times before it was really warmed up right. Thought I would try this in the snowblower since i had not had a new spark plug in about four years. It stopped back firing . Can't wait to try it in my 17 year old lawn mower this summer.

My father, a master technician and engineer recommended this stuff to me many years ago. He had a dozen old toys...cars, boats, motorcycles, airplanes, etc. This is the only additive he recommended and felt that it was good for upper valve train and seats, especially on older machines. I'm using it on all my stuff. Old and new.

MMO is an old-school oil and solvent that can clean and loosen many aged and abused parts. I add it to the fuel of my cars, and feel a difference, although it could be imagined... Much better price here than in local stores, so although I generally prefer to support brick and mortar, sometimes value wins out :-)

I've used it in fuel and oil for close to 50 years.

I purchased an older car that had a ticking - maybe a slight valve sticking problem. I put a small amount of Marvel Mystery Oil in the gas tank and also replaced half a quart of oil while changing oil. One day while on the expressway I changed lanes and all of a sudden this other car changed lanes too. In an effort to get out of the way I floored it. I looked in the rearview mirror and their was this cloud of smoke behind me. I mean huge dark cloud as I raced away. It was amazing, at first a litle scary then I realized my engine needed this. A good blowout. My motor is so quiet and idles so smooth that I hear the cars engine next to me in traffic but not mine. I actually thought on one occasion the engine had stopped but i blipped the gas and yes it was running. I will continue to use this product for the life of my car.

Follow the instructions and your car will be running more efficiently! Thank you Marvel! It's cheaper to buy the gallon in the long run.

I have a few containers of 32oz MMO that I just refill using this. A small funnel is all you need and at the price paid, under 16 dollars, it's a total value. Used with gas (6oz for full tank, 15 gallon tank) and for cleaning additional sludge prior to oil change (remove a quart of oil oil and add quart of MMO, drive for about 300 miles). I have a 2007 Toyota Matrix that has been running smoothly since.

Now that I've been using this product for a few years I can say that this does make a noticeable effort in improving performance of a vehicle. The dirtier the engine the more noticeable it's effect is. You won't notice anything running this in a clean engine save for maybe a deeper hum from the engine and exhaust. My father uses this more than I do and I've seen him use it on a motorcycle that had trouble running after a few years of storage after about 15 minutes from him adding it to the tank it began to run normal like it used to. He's added it to the oil on an old Buick that ran ok and now it runs perfectly fine after having to drain the oil and replace the filter 50 miles later from the check engine light coming on and finding the filter was filled with carbon. I typically add it to the fuel once a month or so and to the oil when it's getting near due for a change.

Ya lo habia utilizado, y si...si funciona, claro que debes hacerlo en varios cambios de aceite y saldran los resultados, si estaba humeando..lo deja de hacer asi de facil..
