Ring Free Plus

Yamalube Ring Free Plus Fuel Additive

Yamalube Ring Free Plus is a concentrated fuel additive used to help remove carbon deposits and keep injectors, rings, and combustion areas cleaner. The common maintenance dosage is 1 ounce per 10 gallons of fuel, with stronger treatment used only as directed.

Designed for Yamaha outboard fuel systems, Ring Free Plus helps support smoother performance by targeting carbon buildup that can affect combustion efficiency, piston rings, valves, injectors, and overall engine response. It is a useful addition to routine fuel-system maintenance, especially for boats that see frequent idle time, variable fuel quality, or seasonal storage.

Why Use Ring Free Plus?

• Helps clean carbon deposits from key combustion areas
• Supports cleaner fuel injectors and intake components
• Helps maintain piston ring performance
• Can support smoother idle and throttle response when used as directed
• Works as part of regular Yamaha outboard fuel-system maintenance

How to Use Yamalube Ring Free Plus

For regular maintenance, use the dosage listed on the product label, commonly 1 ounce per 10 gallons of fuel. Stronger treatment ratios should only be used when the bottle instructions or Yamaha service guidance specifically call for them. Add the treatment to the fuel tank before filling whenever possible to help it mix evenly.

Fuel System Maintenance Reminder

For best results, use Ring Free Plus along with clean, fresh fuel, the correct Yamaha fuel filters, and a regular maintenance schedule. If your outboard has hard starting, rough idle, poor acceleration, or persistent fuel-system issues, inspect the fuel system before relying on additives alone.
