Pros & Cons
Pros
It is also useful in putting in the crankcase a couple of hundred miles before an oil change. I also use it for a general light lube oil and when mixed with a little lacquer thinner it frees rusty bolts about as good as anything else i've tried. Add 3... Read More
It is incredible. Best fix ever. For those things, it's awesome. Will buy again. Great lil product.
Cons
Mmo is a bad product & terrible customer -tech support! Much better deals out there than this seller. It was allegedly supposed to help with the carburetors and cylinder heads. No change in performance.
Highlights
Quality
The red goodness gave me an excellent starting engine with a solid functional choke and even better a smooooooooth perfect running idle
Great product does the trick for gas mileage cleans deposits and restores compression
Ethanol leaves behind very dirty deposits in your fuel lines engine and over time will clog your jets on the fuel injectors
Waited several days then fired it up again the valve came loose about 30 seconds after start
Price
This genuinely saved my family over 4000
Saved me dropping 500 on another power washer
I expected nothing but for 10 why not
I was told that another procedure which required dismantling the engine was next at a cost of 5000
Packaging/appearance
Looks like snake oil but im sold
Competitiveness
It wont harm your engine or anything if not its even better
Nothing i mean nothing works as good as marvel mystery oil
It is not nearly as effective as more modern ones like lucas
We used bardahl engine flush at oil change as recommended by bardahl and switched to 040 synthetic oil
