I'm now a believer in Marvel mystery oil. My F-250 is quieter and runs smoother. I have not noticed any mpg increase, but the truck does run very smooth. Good value product

This product is a great product and the price at Walmart was a great price. Plus I was able to get free shipping which really helps out.

I am very happy with the shipping the two one gallon containers were placed in a box in heavy duty sealed plastic bags and everything was wrapped in paper to prevent them from bouncing around. I am pleased and will buy more. For the price shipped to my front door I am so happy. Marvel Mystery Oil is a tried and true product I have used it in fuel for many years and have never ever had any fuel system related issues on anything I highly recommend it.

MMO is a great additive for gas and oil. I have used it for years with great results in vehicles and lawn equipment. Seems to make them run smoother and longer. Walmart on the other hand is a "hot mess". I ordered 2 gallons and it was on the Fedex truck for delivery when it was returned to Walmart for an unknown reason. I had to reorder the same item in the same quantity with a HIGHER price???? MMO is not the problem Walmart shipping is.
