Yamaha Yamalube ACC-RNGFR-PL-12 Ring Free Plus Fuel Additive

Great product. Keeps my Yamaha running free from build up especially when low speed trolling for hours. Expensive but the results speak for themselves.

Been using this liquid magic additive for years with continuous success in a verity of machines and engine types. From Side by sides, Out Board Boat motors, all gas engines. Jet skis. You name it I've ran this through it once or more. Will make a huge difference. Saw excellent results in a Sea-doo jet ski 1100. After sitting a longer time than normal with fresh gas resulting in initial slow throttle response also sputtering and low power. Was added and ran immediately with excellent running results within 10 minutes with all initial issues resolved with no following issues for entire season of use. Highly recommend. I keep a bottle on hand at all times!!

The best engine combustion decarbonizer! I used Yamahas ring free on a 2014 Subaru Outback with a 2.5 that started consuming oil. Then I realized this oil consumption was causing my engine to have a slight ping around 2000-3000 RPMs. I learned that oil burning carbonized my combustion chamber hence caused carbon to make my engine ping. My car had the ping for about 3 years and it was getting worst. I tried Sea foam and Chevron Techron and they both helped and they are good products but the pinging was still there. Yamaha Ring free has for the first time gotten rid of my pinging problem. I did use it as shock treatment though which requires you to add 2 oz per gallon of gas in your gas tank. It goes in your gas tank so it also cleans injectors. Which would explain why my engine is running so smooth. On top of my engine smooth it has regained new power. Very happy with product. Thanks!

Been using for years. Great product

Didn’t notice any change in performance after a year of using this. There are half price Techron products out there that offer similar results.
