## Questions & Answers

**Q: Why does this product take so long to ship?**
A: I don't know where you shop, but at my local Walmart, this stuff is $30+. Less than that from Amazon and it is delivered to my house.

**Q: Putting this in cylinders and let it soak for a few days and rotate and do it again thing it will help unstick rings i have 2 qts in a 8 qt oil system**
A: That should work. I have one quart in the crankcase of my 54 Chevy & 65  TBird plus add 4 ounces to the gas tank of each car when getting gas.

**Q: Can this be used only as an oil change. Meaning i only use this  instead of oil? Thanks in advance**
A: No.When you change oil,use the usual recommended amount less one quart, and replace that one quart with one quart of Marvel Mystery Oil.

**Q: How long can you store it?**
A: not sure but i dont recall seeing anything saying it has to be used by a certain date - i divided mine into one quart sections so i can mix them with my oil when i do oil changes

## Customer Reviews

### ⭐⭐⭐⭐⭐ My favorite gas or oil additive
*by G***R on April 14, 2025*

I've used this stuff to get seized engines turning again. Ive had trouble finding it but I'm glad to have found it here. I remember buying 25$ gallon jugs of this stuff at my local Walmart. Ah how prices have changed. Overall good product, decent price.

### ⭐⭐⭐⭐⭐ Works better than I anticipated.
*by A***R on March 19, 2025*

Started adding this to my gas and oil changes because a mechanic friend of mine recommended it. I noticed better acceleration and lower rpm’s resulting in a smoother ride.

### ⭐⭐⭐⭐⭐ Try some
