I have a lot of 2 stocks toys, 4 wheelers and hot rods; I play in the Mahajan Desert. Keeping my engines clean is a necessity if I want to keep them going. My Dad turned me onto Marvel when I was a kid, 40 years ago. I only put two things in my gas and oil and Marvel is one. I have used other stuff and check out their properties and they don’t cut it, not even close. Marvel does what it says it does, it’s a detergent that works fantastic in gas and oil and lovers oil viscosity. I use it just before an oil change to get all the dirt out and put it in the gas to keep the junk that builds up in garbage gas we use in CA. If I am going into cold weather States like MN in winter I use it to lower the viscosity of 30 weight oil to keep my lifters from knocking and make sure the oil is pumping without having to high oil pressure. I have blown oil filters off, using 30 weight in cold weather, it’s not good! It turns 30 weight into 10 weight when you do it right. Good stuff and I don’t indorse anything.

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.
