Marvel Mystery Oil in the gallon size.
I'm a very busy man and this is very difficult to find at a good price. Walmart has it but they're never in stock. I need the gallon size because I added as an additive for my big truck. On an older truck this is an excellent additive to keep the valve train in good shape. Noticeable difference in my truck. I'm amazed at Amazon not only had it at a good price but I Can Count On the usual great quick delivery to my home.

Mystery Oil the best.
I started "treating" my 94 Blazer 5.7L at 272,000 miles. I was using a quart of oil every 3,000 miles before the treatment. I used it in both the oil and fuel tank. I now have 283,000 and counting. Other than a very negligible rear main seal leak (which previously existed), I am down to almost no oil consumption over the same mileage. The engine runs noticeably smoother, no longer puffs smoke at startup and has increased power. I used this product for many years and had just forgotten about it. I am very pleased with the results I have seen and definitely recommend it. Thanks.

Decades of quality and I use this in many of my machines. I add to 2 cycle gas too.
I wish I had one of the super cool 1950's 55 gallon metal drums of this like we once had at a shop I worked at when I was a boy. If it were full of MMO I'd most likely use it all up! I have a Valvoline metal can, and it's cool, but MMO is the best of art work and such a quality product.

Great product, poor bottle design
Great product. Only reason I didn’t give it 5 stars is because it spills very bad when trying to pour. Bottle could easily be designed with a none spill spout.

I have been using this for 50 years
This has been used in America for a century. Among other uses, great old school oil and gas additive for cleaning hydraulic lifters and top cylinder cleaning. Also a great penetrant and air tool lube. It smells good too.
