Rated 5 out of 5 by from Following my Dad My Dad, a WWII veteran recently passed away at 97. One of my memories of him is the constant use of Marvel Mystery Oil in all of our cars. He would often have one of those metal quart cans in one hand and a teaspoon in the other, measuring just the right amount to add to the gas tank! He would also faithfully use it to replace one quart of oil at oil changes, and tell me that if you want to do something right, do it yourself. Personally, I am happy to just drop my car at the dealer, but out of respect to my Dad, I do use this product.

Rated 5 out of 5 by from I'm a millenial and love it! I tried this as a replacement for STP Multipurpose Fuel System cleaner to help with the winter weather and this increased fuel economy even with STP-treated gas! I also decided to use a mix of 20% MMO and 80% Pennzoil Ultra Platinum in my 2017 Volvo even though the owner's manual recommends Castrol Edge Professional, and the car actually runs better than the oil recommended in the manual! No wonder this has a cult following!

Rated 5 out of 5 by from Keeps the top end clean! Texted this w pic to all my friends; I did a complete tune-up on my Suburban 5.7 Vortec w 230k miles. Was surprised to see how clean the old plugs were with more than 60k miles (from before I bought the vehicle). I'd say it's an endorsement for Marvel Mystery Oil. I run it religiously with 87 octane.

Rated 5 out of 5 by from The Perfect Product I remember being a little kid in seeing this product in the basement. I recall being memorized by the logo on it thinking how cool it looked but I never knew how good it really worked. After my father explain to me how to use it I have never skipped an oil change or a fuel top off without Marvel mystery oil added to it. I couldn’t ask for a better product for all the vehicles I’ve had ( 6 trucks - 7 cars ). It’s an exceptional product and very well priced. You can’t go wrong for the money. Thank you so much for having a great product that is so well worth the money.

Rated 5 out of 5 by from Best all around Diesel Oil supplement. I have been using this MMO since I was a kid, worked with an Old timer at his shop who restored old Mustangs. About 3 years ago I bought a 2006 Ford F-350 super-duty Diesel with 156,000 on it, it ran good but was hesitating under any load, I was told it was a stiction issue with the injectors and they would more than likely have to be replaced. I looked into other expensive products that were sold to cure this specific problem. And they were guaranteed to work within 4000 miles. I thought let me try the MMO in the crankcase, I bought all new synthetic oil and supplemented the MMO as prescribed which came out to 1 gallon, and within 6 days of driving all stiction was gone. I since put over 100,000 miles on the truck adding MMO every oil change and it runs amazingly quieter and smooth, it is clearly time tested with the results proven. I also use it in a spray bottle to remove rusted bolts and parts, able to take apart hardware that would normally break with other products, works phenomenal.
