Marvel Mystery Oil - Oil Enhancer and Fuel Treatment, 1 Gallon

from oldTexan

This item has been dis-continued at our local store. Some auto parts stores have this size in stock but their price is much higher than Wal Mart. I found that I can get this from Wal Mart online with free shipping which is worth the time and effort!

I love this stuff I put it in my gas I put it in my oil sometimes when I use it in my engines they're sitting to loosen up rings and pistons etc. a couple of days soak and everything usually breaks loose for me

I've used MMO in my airplanes for years. Many aircraft engines that are lower compression can use auto fuel if it's ethanol free. Adding MMO at the recommended rate replaces the lubrication lost from being lead free. I've never had any valve issues and I've been doing this for thousands of hours ...

watch any video you want to. but I always used this growing up before switching to Lucas fuel stabilizer. this stuff works in the oil and in the gas. My plugs are clean my engine is 19 years old still runs great. I use about 4 oz with 10 gallons. buy it by the gallon and it's just about the cheapest

I have been using Marvel Mystery oil for years in my garden tractor, tiller, pressure washer, weed wacker and I add it to the fuel every time there is no better product it does exactly what it says. I have found that Walmart is the best price for 1 gallon and no one has is at a better price.
