How to choose oil for two-stroke engines of boat motors?

Owners of floating crafts are always arguing about which oil to choose for two-stroke engines of boat motors. Let's try to understand this issue.

Types

At present, mineral and synthetic oil for two-stroke engines of boat engines are presented to consumers. In order to dwell on a specific solution, it is sufficient to single out the main differences of these lubricants, to identify their disadvantages and advantages.

The main difference in the nature of the above oils lies in their molecular structure. Therefore, it is necessary to look for differences in their very basis.

It should be noted that the synthetic oil for two-stroke engines of boat motors is stable, because it is made in accordance with the specified parameters of the engines. Such funds are most often purchased for servicing engines of specific brands.

The stability of the chemical composition of synthetic bases allows to achieve high efficiency of the engine, operating it in a gentle, safe mode. In other words, the system will not undergo drastic changes that will affect the reduction of the engine's operational life.

Mineral oil for boat motors 2t is less fluid, which is its main disadvantage. The reduced penetrating power of such a solution can affect the performance characteristics of the engine. At the same time, oils of this category are more affordable than synthetic ones.

Characteristics

When selecting oil for two-stroke outboard engines , the following parameters deserve attention:

1. Level of viscosity - determines the ability of the engine to work in separate modes, affects the wear rate. The higher the engine speed, the less viscous oil for two-stroke engines of boat engines should be selected.
2. Ash content - the lower the parameter, the slower the formation of carbon deposits on the spark plugs and, accordingly, the wear of the engine. Preference should be given to the lubricating bases of fine cleaning, as well as to products containing special ashless additives.
3. The combustion temperature is one of the most important characteristics for users who choose oil for boat motors 2t. The parameter in many respects depends on the need for regular renewal of the lubricant composition.

Which motor oil is better for boat motors?

As practice shows, the highest demand among boat owners is enjoyed by the engines of Suzuki, Yamaha and Tohatsu brands. For these engines it is necessary to select lubricants individually.

If we talk about the Suzuki units, then the replacement of oil in the boat motor here should be done using synthetic bases. This oil will cost about 500 rubles per liter.

Yamaha engines are suitable even for automotive lubrication, since the engines of this brand are considered more robust. For replacement, you can find a fairly inexpensive oil, costing about 300 rubles per liter.

In the case of Tohatsu engines, cheap mineral car oils are not recommended. Such engines are weaker in comparison with the Yamaha brand. Therefore, the only rational option here is the purchase of a high-quality synthetic oil cost of around 700 rubles.

How long will the engine run without oil?

The oil protects the boat engine from wear as a result of the friction that occurs during the movement of the piston components. It is quite natural that when the stock of lubricant is depleted, the motor does not start at full capacity. In this case, the probability of the final failure of individual elements of the system increases.

In fact, the boat engine can function properly without oil. However, in this case, work on idling will be more often traced. Even after the full consumption of lubricant, a small oil film remains on the motor walls. Until the end of its life, the engine can cope with the tasks.

Why is it important to follow the manufacturer's instructions when using oils?

In the development of certain lubricants, each manufacturer relies on specific technical conditions. In the course of production, the interaction of oils with certain materials and technologies is taken into account. In other words - each motor is developed taking into account a set of conditions for its operation.

There is no exception to the need to maintain a specific percentage of oil in fuel mixtures. With an increase in the amount of lubricant in the mix, the owner of the floating craft can not avoid problems concerning the occurrence of carbon deposits in the candles and in the combustion chamber of the engine, as well as coking of the piston rings.

Reducing the rate of lubrication in the fuel mixture will lead to oil "starvation" engine. As a result, it is necessary to put up with premature wear of the motor and regular breakdowns.
