Oil for water equipment
20.05.2024
Summer is approaching, and with it the season of sea adventures. It's time to start preparing your ship for sea. Among all the preparatory stages of water transport, oil change in the engine is one of the most important procedures. Boats often have two-stroke engines, so in this article we will analyze what they are and what oil to choose for them.
What are the distinctive features of two-stroke engine oil?
Lubricant
In a two-stroke engine, unlike a four-stroke engine, there is no independent lubrication system. The lubrication of the elements, in turn, proceeds as follows: the oil is mixed with fuel, poured into the tank, when the engine is running, it enters the combustion chamber and the resulting fuel-oil mixture settles on the necessary parts, thereby lubricating them.
It would seem that such a system is simpler and this is certainly true, but such an engine is very picky about the quality of the oil used. Before buying, it is necessary to familiarize yourself with the requirements of the engine manufacturer and the operating rules.
Carbon deposits
Another important property of oil for a two–stroke engine is preventing the formation of carbon deposits.
For this purpose, two-stroke engine oils have a unique formulation, which includes special additives.
The use of automobile and motorcycle oils in outboard motors is not recommended. But if you suddenly gather, do not forget to take the oars with you, because the wrong choice of oil can disable the boat's engine, and you will be left adrift at sea.
What kind of oil should I choose?
To do this, it is enough to understand what type and tolerances of oil are suitable for your engine.
Types of oil.
There are two main types of outboard motor oils in the world: mineral-based and synthetic.
Mineral-based oil is produced from petroleum and refined in accordance with special requirements. It is more common on the market and is relatively inexpensive. Such an oil can provide good lubrication and wear protection, but it does not have as long a service life as synthetic oils.
Synthetic oils are made from artificial chemicals and only some ingredients can be made from petroleum. Of course, they are more expensive than mineral-based oils, but this is the case where a high price is equivalent to quality.
Also, there is a semi–synthetic oil - this, as you might guess from the name, is a cross between mineral and synthetic oils. It costs less than synthetic, but it is close to it in properties.
Oil tolerances for two-stroke engines:
TC-W3 standard oil is ideal for lubricating two-stroke outboard engines.
TC-W3 is a special standard for two-stroke outboard motors developed by the National Association of Shipbuilders of the USA (NMMA). The requirements of the standard are aimed at ensuring the anti-corrosion properties of boat oils and ensuring the cleanliness of the piston rings of the engine. Since ash in the presence of water contributes to the formation of compounds that cause sticking rings, all TC-W3 oils are ash-free. Oils of this standard decompose in water, therefore they are safer for the environment. TC-W3 meets the requirements of the API TC standard, but the TC API is not applicable for outboard motors.
The FQ brand produces oil for water transport with a TC-W3 tolerance. More details can be found here.
Other 2T engine Oil standards:
TC is a certificate for two-stroke engine oils issued by the American Petroleum Institute (API). It is used in the engines of chainsaws, trimmers, cultivators, snow plows, snowmobiles, motorcycles, scooters, etc.
JASO FD, FC, FB, FA is a Japanese standard of oils used mainly on Japanese machinery. The reason for the development of the standard was the rapidly growing requirements for oils and their environmental impact. These oils are excellent for use in two-stroke motorcycle engines.
To sum up, the main rule when choosing an oil is not to save money and carefully study the operating instructions. Incorrect oil can lead to significant repair costs.
