Marvel Mystery Oil - Oil Enhancer and Fuel Treatment, 32 oz.

great stuff to run thru engine before a up coming oil change...and a perfect fuel system cleaner used it since my first car in 1985 witch was a 75 dodge van and still today never had a fuel related item fail in my car motocycle and boat and lawn mower snowthrower and weed wacker ...dump half bottle in a full tank of fuel go for a cruise works great i do about 6 times a year in car and my 2002 kawasaki 1200 no fuel injection used since i bought new ...begin and end of season bike just turned 30 k 2025

This stuff works ... use in gas to maintain fuel system, especially in seldom driven vehicles and motorcycles or in small engine equipment. Put in engine oil about 500 miles before oil change to keep engine clean and running smoothly. Measure it out... use no more than 4 oz per 10 gallons (2 oz per 5 gallons, 1 oz per 2.5 gallons, 0.5 oz per 1.25 gallons - etc.) of gas... sometimes, using less, gives better gas mileage results...it varies. In the oil, I use 2 to 3 oz per quart of oil in the engine... you can use up to 20% of the engine's oil capacity... but, for maintaining a clean engine, the 2 to 3 oz per quart of oil in the engine works well and won't cause a problem with overfilling if the oil level is at it's max fill position.

i have used this product for over twelve years, it is an excellent product for two and four cycle engines. It has been used for over one hundred years. Great product. Keep carrying this product. Thank you.

I have uses this in all my vehicles over the years. I currently have a 2012 Toyota Camary,traveling using different gas stations over the US. This treatment in my fule tank keeps the fuel flowing smoothly even if the gas a different stations are not the same quality.

Excellent price, fast shipping, and directly as described. This bottle is large enough where you can get anywhere from 3 to 5 uses out of this bottle depending on your vehicle. if you were to go to a AutoZone or something similar the price would be about double. I use it every time I fill my car up.
