USES: MMO can be used in a car to clean out the entire fuel system, including the fuel pump, and fuel injectors. On an older vehicle, this can also clean out your carburetor, which normally can become troublesome with age. Like I said earlier, MMO is also a trade secret to those who race cars, many will swear by this product.MMO can also be used in RV's, which use diesel engines or the big rigs as well. It can also be used in, boats, ATV's, and landscaping equipment such as, mowers, trimmers, blowers. I also like MMO, cause it can be used in the oil crankcase of every engine. Over time, your engine can develop carbon deposits, having MMO in the crankcase will clean out these deposits. Then you can get rid of them at your next oil change.MY EXPERIENCE: My experience with MMO has been well, marvelous! I have been using it in my landscaping equipment for years now. And I find that machines, which I am treating with MMO, last longer then those that are not treated. For example, I can run MMO in the gas and oil of a Briggs V-Twin engine. I can then have another duplicate engine next to it without the MMO treatment.I can run both engines for 48 hours, and I can guarantee you, if I pull them both apart, the engine which was treated with MMO, will be the cleanest one. Another difference is with valve lifter ping, I am sure you have heard that from your engine before. Treat your engine with MMO, and I can guarantee you that the ping will go away. Why? Because, MMO cleans and lubricates your valve lifters.THE MANTIS TILLER: As some of you may know, I used to own a 2-cycle Mantis tiller. Well, after it was 3-years old, I was having some major troubles with it. What it needed was a carburetor rebuild kit, but since I was on the job, I had no time for that! I grabbed my bottle of MMO, which I bring with me, I applied two cap-fulls of this stuff to the tank. After running the engine at full throttle for 10-minutes, all of the sudden I gained engine power. And I was able to sustain smoother throttle response as well.
