Rated 5 out of 5 by from Should be called, "Miracle Oil" Yes, its that good 32 years ago I worked in a large international manufacturing plant ( large machine shop). The maintenance manager was a huge believer in MMO. I remember he mixing MMO with his gear oil for all our large and small lathes. These machines were mega huge and mega expensive, and some were very old, all used 24/7 and his secret of long life and 100% uptime was contributed to Marvel Mystery Oil! I remember my manager would brag on the condition of the gears when he had a lathe gear box open; he would point to the clean, like new gear condition as say, "thats" because of the Marvel Mystery Oil! His devotion to MMO has always stayed with me all these years. If something in the plant stopped working, he was the one fixing it. I know he believed MMO made is job and life much easer! My manager would always talk about how MMO was simply the best stuff ever and he would put it in everything that had a gear. Then about 20 years ago I decided to try some racing gas in my Harley, big mistake as it damaged my carb and my after market petcock ( gas turnoff ) became impossible to turn on or off, I assume the o-ring swelled from the racing gas as that gas all but melted all the seals in the carb. The racing gas based on what the Harley mechanic told me not only damaged my carb but damaged my valve seats; After he replaced the carb, he suggest the valves may re-seat or may not with time. I thought well now what do I do and then my old maintenance manager came to mind and Marvel Mystery Oil. I replaced that racing gas with normal gas and I then a few oz of MMO in the tank and to my amazement instant fix! The gas turn off ( petcock) not only now worked but was smooth as silk unlike even when new as the MMO lubricated the rubber parts! After a few miles my valves re-seated and now 21 years later my Harley runs better than new with nothing but regular oil changes and MMO in the gas for 21 years! I now use MMO in the gas of all my small engines. I keep MMO in my stored ( 100% pure gas, I don't use ethanol in small engines) and I mix in some STA-BIL storage fuel stabilizer and have had fantastic results with that mixture of MMO and STA-BIL. I find my Harley actually runs better ( stronger, smoother, better throttle response. ez starts ) on that mix than even fresh gas without the mix? Mystery right? I have been running this MMO and STA-BIL pure gas mix for many years and now have zero fuel issues in any small engine or my Harley. I get a full year or more on that stored gas with no problems. I do mix a little MMO in my lawn mower oil and my work van both oil and gas ( not every fill up but most). I add the MMO to top off the oil or before a change to help keep oil passages clean. MMO has been in almost every Harley gas tank of gas but I have noticed when I'm on the road and I do fill up and don't add MMO to the gas I can feel that gas cutoff getting tight on that one tank so if nothing else MMO, based on my experience, is a requirement for gas (petcock) cutoff o-rings and I can actually feel it working and feel the silky lubrication with every turn off and off of that gas petcock. I don't know for sure, but with my experience I would expect a little MMO would be good for fuel pumps, any rubber o-rings, carbs pars, fuel injectors, fuel lines etc anything that comes in contact with gas. When I can feel it is actually doing something "working" with my fuel cutoff its not just a "I put some additive in my gas and I guess Its working as the bottle says it works" I can tell in one tank my rubber seal loves this stuff and all but require it! I have also noticed the inside of my Harley gas tank looks new when my old motorcycle friend had to replace his gas tank. I am over 21 years now without a carb rebuild on that old Harley and that same gas turn off is still smooth as silk. Marvel Mystery Oil will always have a place in my garage! I think of Marvel Mystery Oil as I do aspirin. Many new products come and go but when I find myself with a "headache" old school tried and true can be the best option.

Rated 5 out of 5 by from Superb lubricant I've been using Marvel Mystery Oil in various cars and trucks since the 60's. I still use it in my 1940 Plymouth business coupe and 1964 Dodge D100 Sweptline. It protects the valves and cylinders against damage from modern fuels. Thanks MMO for over 50 years of engine protection.

Rated 5 out of 5 by from Runs like a champ I had a old Chevy Silverado 350 I put in the after oil change vehicle starts up easier. There was sludge on the lifters after few hundred miles there looking cleaner than ever im glad I used this stuff. I also but it in gas and even more improvement. my vehicle runs like new thanks to marvel mystery.

Rated 4 out of 5 by from WRONG COLOR I love Marvel Mystery Oil and have for many years. My father taught me the benefits of it 60 years ago. It goes in all my gas vehicles and diesel farm equipment. Here's the problem . Red tinted diesel fuel in a road vehicle will get me a huge ticket from DOT. Would love a choice of colors.

Rated 5 out of 5 by from A staple in my shop I've been using MMO for decades. I own and restore vintage motorcycles and have used MMO on many of them. I use MMO on older machines when lifters begin to stick or rings begin to stick in piston grooves causing blow-by. I've been very successful in restoring compression and reducing blow-by with MMO. I have a Mercedes 560SL that occasionally gets sticky lifters which are easily freed and lubricated with MMO.

Rated 5 out of 5 by from I recommend it to everyone! Every year in the spring when I'd get my motorcycle rolling for summer (2001 Suzuki Intruder), I'd have problems getting it fired up. It would start firing on one cylinder then eventually two. The tank of old gas was horrible to suffer through and as the years went by, it took more tankfulls to get it to run smoothly. I was having trouble keeping it running at a stop light. A friend recommended Marvel Mystery Oil. In one tank full it ran like brand new! Not kidding. Later I had problems with the wet clutch slipping because I was using the wrong oil. Using Marvel in the crankcase cleared that up too! I use it everywhere! There is always a jug in the garage. I've never come across anything like it, best ever!

Rated 5 out of 5 by from You don’t understand This summer I will be 59 years old. I went to college in 1979 and worked in a gas station to support myself. A very old man would come by once a week with his old Ford to gas up. He always had a small red bottle of Marvel Mystery Oil at had and added it to the gas tank. Remember, this was the era of leaded gas! I asked him about it after a couple of years and he told me that it was “the secret to long engine life” I have used it ever since and have never had and Engine problem in 40 years of use. I highly endorse Marvel Mystery Oil and am a lifetime customer!
