This is such a wonderful product for an engine. My dad told me when he had several trucks at his business that he got one serviced and the mechanic told him the trucks engine was the most lubricated and well maintained he'd ever seen. Since then I give my car 3 “gulps” every other fill up.

Great for lubricating parts

This solution works well with the sticky gasoline gage reader in the tank for your dash readout operation. Otherwise, it will cost you an arm and leg to repair the unit inside the gas tank of it's NON-Reading on your gage panel. Just add what the bottle says to get the results.

Gas Gage Works Again

Been using marvel mystery oil since I was teenager . Imo it's best addictive  on market to protect your engine … cylinder heads …. Lubricant… oil and gas addictive .  I only use it with my gas … it improves performance and gas mileage and extends life of your engine . After you try bottle you will be hooked !! A product that improves performance… gas mileage and protects your engine !!!

My engines just keep running. I have used this for more than four decades I think. The last two cars I bought new and kept for over 17 years each, one I'm still driving. It is still running perfectly with no problems whatsoever with the engine (or anything else really). Can I tell you this is the reason - NO. Do I think it has helped - YES. I just had the recommended measure to my fuel tank with each fill up.

it just seems to work. the engines keep running.

I use this in the race motors after the race. It keeps the cylinders well lubed and fights off the affects of the methanol.  
I also use it in the fuel lines as well as the fuel pump.

MMO is magic.  Have used it forever.  Cures so many issues while extending life and performance.  I've owned EVERYTHING, sometimes high-mileage luxury cars. Just the best (and a quart with oil change and 4-6 oz with full tanks once per month.

Not a Mystery.  Magic.

Add this Marvel Mystery additive before each gas fill. It makes my car run smoothly. My partners car started making a knocking noise. He added this to his fuel tank %26 his car quit making the noise. I also think my car gets better gas mileage.

Motor runs better

This is the best stuff on the market the best product for the money I will continue to use it. My father used it, and I've seen it as a child and I will continue to pass it down to my children to use this product.

[This review was collected as part of a promotion.] This stuff is way too expensive for me to buy anywhere else. I use it once a year right before an oil change, to flush out any buildup and residue.

Used MMO for decades as fuel and oil additive to keep engines  running clean.Terrific for small engine s  to keep alcohol in gas from gumming up the carb and prevent corrosive harm.

All time fuel and oil additive.

I have a 2012 FORD E-350 Super Duty Econoline. I added 4 ounces per 10 gallons of gasoline. I didn't add it to my oil when I changed it, but my vehicle no longer starts. It says this product DISSOLVES OIL AND HAS NO REAL BENEFIT FOR MY ENGINE THEREFORE DAMAGING IT! My engine was good before the use of this oil. I recommend just changing your oil or getting a mechanic to look at it before using this snake oil.

Doesn't work DO NOT BUY!!
