Features

  • Ring Free PLUS and Fuel Stabilizer & Conditioner PLUS fight fuel system corrosion, phase separation and fuel oxidation. This improves performance and extends the life of your Yamaha. (For marine applications only.)
  • Though it may be new to you, Ring Free has actually been around for more than 20 years. Originally developed to decarbonize engines, we reformulated it in the late 2000s to also fight ethanol sulfate salt corrosion. To reflect this added benefit, it was renamed Ring Free PLUS, and its been keeping engines clean and running efficiently ever since.

Description

Provides superior deposit control, cleaning fuel injectors, carburetors, intake valves, intake ports and combustion chambers. It also protects fuel system metals from ethanol sulfate salt corrosion. 12 oz. Bottle

    • AMAZING PRODUCT!!!!
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!! ... show more

    • Melts your carbon in the Combustion chambers!
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! ... show more

    • Skeptical
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.

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

    • Happy after seeing piston top pics. Cleaned at least 2/3 of piston tops.
I saw this additive on YouTube :DIY Dave that has 216K views. I did a milder shock treatment using two12 oz bottles. Took piston top pics this morning Just finished Yamalube Ring Free mild SHOCK treatment on my 177K miles Dodge Caravan 4 cyl, Never put in top tier gas before last year Used just 24 oz , not 32. Put in 12 OZ bottle then filled 20 gal tank. Then waited until tank was low and put in another 12 oz bottle with just 10 gal. gas. Before, top piston pics were covered with carbon, This morning pics... 2/3 to 3/4 of piston tops were bare metal!! Works. ... show more

    • Well bragged about & created by Chevron
Developed by Chevron. Looks like oil to me and smells strong enough. Yes they add aroma to plenty of fuel treatment and some you want respirator like original AC Delco X66P. Should clean good as lots of reviews on BTOG (Bob the oil guy) brag about it.
