Owners of boats always argue about which oil to choose for two-stroke engines of outboard engines. Let's try to understand this issue.
Types
At present, consumers are offered a choice of mineral and synthetic oil for two-stroke engines of outboard engines. To dwell on a specific solution, it is enough to highlight the main differences of these lubricants, to determine their disadvantages and advantages.
The main difference in the nature of the above oils is their molecular structure. Therefore, it is necessary to look for differences in their very basis.
It should be noted that synthetic oil for two-stroke engines of boat engines is stable, since it is produced in accordance with the specified parameters of the engines. Such tools are most often purchased for servicing engines of specific brands.
The stability of the chemical composition of the synthetic bases allows you to achieve high engine performance by operating it in a gentle, safe mode. In other words, there will be no cardinal changes in the system that will affect the reduction in the life of the engine.
Mineral oil for outboard motors 2t is less fluid, which is its main drawback. Reduced penetration of such a solution may affect the performance of the engine. At the same time, oils of this category are distinguished by a more reasonable price compared to synthetic ones.
Characteristics
When selecting oil for two-stroke outboard motors, the following parameters deserve attention:
- The level of viscosity - determines the ability of the engine to work in separate modes, affects the wear rate. The higher the engine’s speed, the less viscous oil for two-stroke engines of outboard engines should be chosen.
- Ash content - the lower the parameter, the slower the formation of soot on the spark plugs and, accordingly, engine wear. Preference should be given to thin-lubricating lubricants, as well as products that contain special ashless additives.
- The combustion temperature is one of the most important characteristics for users who choose oil for 2t outboard engines. The parameter in many respects depends on the need for regular updating of the lubricant composition.
Which engine oil for outboard engines is better to choose?
As practice shows, the highest demand among owners of watercraft is used by Suzuki, Yamaha and Tohatsu brands. For these engines, it is worthwhile to select lubricants individually.
If we talk about Suzuki units, the oil change in the outboard motor here should be made using synthetic substrates. Such oil will cost about 500 rubles per liter.
For Yamaha engines, even automotive grease is suitable, since the engines of this brand are considered stronger. To replace, you can find a fairly inexpensive oil, costing about 300 rubles per liter.
In the case of Tohatsu engines, the use of cheap mineral automotive oils is not recommended. Such engines are weaker compared to Yamaha units. Therefore, the only rational option here is to buy high-quality synthetic oil at a cost of around 700 rubles.
How long will the engine run without oil?
The oil protects the boat engine from wear due to friction that occurs during the movement of the piston components. It is natural that when the supply of lubricant is exhausted, the motor does not start operating at full capacity. This increases the likelihood of a final failure of individual elements of the system.
In fact, the boat engine can function properly without oil. However, in this case, idling will be more often traced. Even after complete loss of lubrication, a small oil film remains on the motor walls. Until its resource runs out, the engine will be able to cope with the tasks.
Why is it important to adhere to the manufacturer's instructions when using oils?
When developing certain lubricants, each manufacturer relies on specific specifications. During production, the interaction of oils with certain materials and technologies is taken into account. In other words, each motor is developed taking into account the complex conditions for its operation.
The need to maintain a specific percentage of oil in fuel mixtures is no exception. With an increase in the amount of lubricant in the mix, the owner of the boat cannot avoid problems concerning the occurrence of soot on candles and in the combustion chamber of the engine, as well as the coking of piston rings.
A decrease in the lubrication rate in the fuel mixture will lead to oil starvation of the engine. As a result, you will have to put up with premature engine wear and regular breakdowns.
