Review: Works awesome for my marine motors - Been using for years. Great product
Review: 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!

## 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 it’s been keeping engines clean and running efficiently ever since.

### ⭐⭐⭐⭐⭐ Outstanding.
*by A***R on September 2, 2025*

Used on Acura RSX Type S with caked carbon deposits on top of the pistons (not used on a boat). Used one bottle in gas tank (doing the intense procedure version) & it completely cleaned off the top of my pistons. I have never gotten carbon this caked completely removed; not even multiple B12 piston soaks have worked this well. This needs to be an Amazon Prime product!!! Confirmed using bore scope & no more oil burning from the K20z1.
