Why Ring Free?
Yamaha has recommended Ring Free in both 2 and 4-stroke engines for a reason. Today’s fuels are changing; engine operational patterns and applications change from boat to boat.
Carbon deposits are a reality in all internal combustion engines.
Many customers are bargain hunters when it comes to purchasing fuel and oil for an expensive investment. Many of the bargain gas stations will also look for cheaper fuel, which in turn means cheaper fuel additive packages in order to increase their profits on fuel sales. These cheaper additive packages will leave deposits.
Yamaha recommends the use of “Ring Free” in all of its outboard models (2-Stroke and 4-Stroke). “Ring Free” has proven to be an excellent fuel system and combustion chamber cleaner. For continuous use, maintain 1 oz of “Ring Free” to 10 gallons of fuel. “Ring Free” may be used as a shock treatment for engines that have never run this product before.
Shock treatment level is 2 oz to every gallon of fuel. On 4-stroke models, after the shock treatment, the engine oil MUST be changed due to possible oil dilution. On 2/4 stroke models, after shock treatment, the spark plugs should be changed due to possibility of plug fouling occurring from the carbon deposit loosening.
Yamaha’s Fuel Conditioner/Stabilizer is another excellent product to use on a continuous basis. Today’s fuels are constantly changing from season to season and area to area. These changes range from volatility levels to oxygenate packages. It is also possible that the fuel purchased at the pump may not meet the rated octane level. Fuel degradation time may vary from season to season and area to area. This degradation does not vary between octane levels. The degradation time is established by the amount of time the fuel has sat between the blender and the final use in the combustion chamber, and the amount of time it takes your customer to use a tank of fuel. For this reason Yamaha recommends the continuous use of fuel conditioner/stabilizer.
For continuous use, add 1oz of fuel conditioner/stabilizer to every 2 gallons of fuel. For storage purposes more than 3 months, use 1 oz to every 1 gallon to ensure the fuel system is properly protected. Have the customer fill the fuel tank prior to his last usage for the season and add the proper amount of fuel conditioner/stabilizer. Use the boat for the last time. When finished, top off the fuel tank with gas and the proper amount of stabilizer for the additional fuel added.
If the fuel has degredated, there is nothing that will “Recondition” the fuel. Once it is bad, it is bad. The fuel conditioner/stabilizer will slow down the degradation process. It does not prevent degradation.
Combustion Chamber Cleaner:
Yamaha’s Combustion Chamber Cleaner is a good shock treatment for older engines that have never used “Ring Free.” This cleaner is to be used directly from the can into the intake tract of the engine. The engine must first be brought up to operational temperature. Run the engine at fast idle and spray the appropriate amount of cleaner into the intake tract. For best results, spray at least 10 seconds for every 100cc of engine displacement. Evenly divide the time of spray for multi-cylinder models. After the engine has been sprayed turn the engine off and let it sit between 15 and 60 minutes depending on the severity of carbon build-up.
Do not let sit longer than 60 minutes with combustion chamber cleaner in the cylinders.
After the appropriate amount of time, start the engine and run under a medium load. Do not accelerate hard for at lease 10 minutes. If a repeat application is required, follow the same procedures. After the shock treatment, replace the spark plugs on 2/4 stroke engines. On the 4-stroke engine, replace the engine oil and filter after treatment, due to possible oil dilution.
Stor-Rite Engine Fogger:
For long periods of storage (3-months or more) it is recommended to use Yamaha’s Stor-Rite Engine Fogging Oil for 2/4 stroke engines. The fogging oil is designed to provide protection from rust and corrosion due to salt water, moisture and acidic combustion. It is designed to be sprayed directly through the intake tract. Start the engine on an external water supply (flush attachment). Let the engine come up to operational temperature, set the engine at fast idle, and spray fogging oil into the intake tract. Apply approximately 1 minute per cylinder (Example: A 6-cylinder engine will require 6 minutes) apply evenly 1 minute per cylinder.
Silicone Protectant and Lubricant:
Yamaha’s Silicone Protectant and Lubricant is designed to help resist rust and corrosion on external components of the outboard engine. The silicone spray may be applied on all components under the cowling except for the oxygen sensor housing. Also, when applying the spray, do not spray inside the air box or throttle bodies. This spray is not to be used on internal engine components. Depending on the conditions, the most severe salt-water use may require the application to be performed monthly. When there is a salt/corrosion build up prior to using the silicon spray, it is recommended to wash the engine down with fresh water and letting it air dry in the sun. Again, when washing, you must prevent the introduction of water into the intake tract and oxygen sensor housing.
Yamalube 2-M Oil Increased Engine Life – All 2-Stroke Models
Oils are not created equal – not even TC-W3 oils. Yamalube 2-M has been specifically designed for use in Yamaha 2-Stroke outboards for reliability and durability. Your customers should understand the importance of using Yamalube 2-M. Other oils can cause increased wear and greater chance for oil-related failures.
Here is an example. Yamaha tested identical outboards by running them for 150hours at full throttle under load. One had Yamalube 2-M, the other was run using a nationally recognized competitor oil (not a “bargain” brand). After the test, we tore the engines down and inspected them carefully. We measured wear in the critical wrist pin boss area on the piston. Yamalube’s average wear was .005mm, compared with the competitor’s .025 mm. Yamaha also inspected the engines for piston ring scuffing and sticking. The results showed the superiority of Yamalube: no scuffing with Yamalube, scuffing with competitor’s oil.
What does this mean to you? Simply this: Using a cheaper oil to “save money” can actually end up costing the customer much, much more in the long run. Even a well-known brand like the one in our test can result in significantly more wear than genuine Yamalube. Some customers have been led to believe that all oils are the same if they are TC-W3. This is simply not true. TC-W3 is only a minimum standard. Yamalube surpasses the standard with highest quality ingredients and a carefully blended additive package to provide superior lubrication with fewer power-robbing deposits that can shorten engine life.
Yamaha’s business is outboards. We have an unmatched reputation for quality, performance, and durability with our engines. We’re not going to risk that reputation with an inferior oil product. Yamalube 2-M is blended to be the best oil for our engines.
Use Genuine Yamaha Parts and Accessories, Use Yamalube!
