10 best oils for outboard motors

Outboard motors are a special type of internal combustion engines that convert the energy of an explosion of a fuel mixture into mechanical energy of rotation of a propeller blade. Like any other engine, outboard engines also require the use of special technical fluids, which include such ordinary motor oil.

The use of oil for boat engines in Russia went through several rather curious stages. At a time when the domestic market was filled only with models of domestic production, exploiting the oil was akin to insanity. Autol was used, the combustion of which led to the formation of soot on the pistons, and also attracted a huge amount of burns, the benefit is that any “sore” was amenable to painstaking treatment. From the moment of overcoming the trade barrier and entering the domestic market of foreign products, Avtol imperceptibly went aside, giving place first to mineral and then synthetic oils, which considerably saved the budget of the already rather poor citizens of the country.

To date, the market avtomasel has hundreds of different samples, suitable for pouring into a standard outboard motor. Alas, not everyone has high quality, which makes the selection process even more difficult. Having carefully studied the situation, we ranked the ten best oils for boat engines in two main categories: for two- and four-stroke power plants, the optimum qualities of which were tested by hundreds of satisfied consumers.

The best oils for two-stroke outboard motors

5 PATRIOT Super Active 2T

The representative of the Chinese company PATRIOT, Super Active 2T semi-synthetic engine oil, which is in high demand in the domestic market, opens the rating of oils for two-stroke workers. The incredible popularity of this variety has arisen due to consumer cravings for the entire budget - the cost of a liter of Chinese semi-synthetics is comparable to the cost of autol, so often remembered by experienced anglers or motorboat owners.

But such a rough comparison does not quite correctly reflect the essence of the PATRIOT Super Active 2T: its quality indicators are really commendable. Despite not the most advanced formula, Chinese manufacturers managed to reduce the level of carbon on the pistons through the almost complete combustion of the oil in the mixture. But the main feature of the technical fluid from the "Patriots" is versatility - with such a low price, this oil covers almost all special equipment, ranging from outboard motors, to motorcycles, snowmobiles and garden equipment.

4 Ravenol Outboardoel 2T Mineral 1l

Motor mineral oil, produced in Germany, meets the highest quality standards required by 2-stroke outboard motors. The manufacturer has been on the Russian market for many years and is aware of the problem with the quality of gasoline, therefore all nuances were taken into account when developing a complex chemical formula.The composition of the engine oil includes special high-quality additives, reducing to a minimum sediment on the crankcase, and the engine remains clean even after several years of use. Bearings and cylinder-piston group due to better lubrication can withstand long-term extreme loads.

The components of the solvent contained in this oil provide a low flash point and reduce visible emissions. Connection with gasoline of various purities occurs without changing the octane number and the mixture does not lose its properties when stored in a canister. The blue dye in the oil helps to control the fill level easily. Its use in two-stroke outboard motors ensures a long service life and minimal wear of moving parts.

3 Yamalube 2-M TC-W3 RL Super 2-Stroke 1l

Yamalube mineral engine oil is designed for use in modern water-cooled boat motors and complies with the strict standards of the Japanese Yamaha water equipment. It can be used in two-stroke direct injection engines, with premixing or in an automatic system. The oil was developed for the harshest operating conditions with the best protection against wear and seizure of the pistons. Special additives prevent deposits on the rings and spark plugs in highly accelerated 2-stroke engines, protect against corrosion, and also reduce air emissions.

Yamalube oil has an increased shelf life and can be stored in any temperature conditions, while it does not lose its properties and you can be sure of its quality after a long period of time. Thanks to its ideal mixing with the fuel, the oil prevents the formation of sediment, leaving no sticky deposits. The proportions are one of the most economical and range from 1 to 2 percent, depending on the operating conditions. Included is a yardstick for easy mixing.

2 Motul Outboard Tech 2T

High-quality semi-synthetic oil from the monopolists of the market of technical fluids for special equipment, demonstrating excellent performance in terms of the sparing impact on the environment. To the extent of creating an “environmentally friendly” oil, Motul was forced by environmentalists to restrict the use of two-strokes or to develop new quality standards. Since the main "trough" of the French company is the production of technical fluids for special equipment, the option of restricting the use of such engines would mean inevitable death.

The special composition of the semi-synthetic fluid made it possible to significantly reduce its consumption for the creation of the fuel mixture, which naturally affected its efficiency. However, having won in the expenditure component, Motul prudently equated costs with higher costs, which discouraged regular customers and led to some stagnation in demand.

1 LIQUI MOLY 2-Takt-Motoroil

The semi-synthetic engine oil from the German company LIQUI MOLY, which has excellent performance in the operation component, is quite expected to become the category leader in the two-stroke class. Despite all the specifics of oils for outboard motors, the Germans managed to create a really cool product. LIQUI MOLY 2-Takt-Motoroil has a low detonation temperature threshold: something around 120 degrees Celsius. In this regard, the combustion takes place more fully, intensively, and the destructive carbon on the piston is formed in a much smaller quantity. On the other hand, this entails good financial losses, since the intensive combustion of technical fluid will require periodic refilling.

Thus, if the price indicator is at the forefront, it is worth thinking about the expediency of buying LIQUI MOLY 2-Takt-Motoroil. In the case of putting the key quality indicator in the category, German oil will be the best choice, since the company's products are widely distributed in the secondary market and at authorized dealers.

The best oils for four-stroke outboard motors

5 Mannol 7820 Aqua Jet 4-Takt 1l

Mannol 7820 Aqua motor oil has been specially developed for four-stroke power boats and jet skis equipped with turbochargers. The stable formula of additives in the best way contributes to the stable operation of the lubrication system of jet engines and prevents the formation of small particles that can damage the mechanism.

The excellent anti-corrosion properties of the oil prevent the formation of rusty deposits, which inevitably appear upon contact with water. The components contained in the composition of the engine oil, reduce friction in moving parts, ensuring their smooth operation for a long time. Due to the low-ash composition of the oil, the carbon does not form carbon deposits from soot and lacquer deposits, which makes it possible to use water equipment equipped with catalytic converters. Even in the case of accidental water ingress into the housing, the oil is able to work effectively at full speed without breaking the lubricating film. The product specification and approval are as follows: SAE 10W-40, API SL, JASO MA.

4 Wolf Outboard 4T 10W30 1l

High-grade semi-synthetic oil is based on carefully selected base oils of the highest purity and is designed for modern four-stroke engines, the most famous of which can be considered Mercury Marine and Yamaha. The oil was developed in accordance with the requirements of NMMA FC-W and is able to provide increased protection against the occurrence of rust, which quickly forms under the influence of salt water. Having in its structure compounds of molecules of molybdenum and zinc, the oil comprehensively protects against aggressive media and maintains the engine in exceptional purity.

Special additives provide the oil with better oxidation resistance, help to penetrate faster throughout the system and maintain the stability and reliability of the lubricating film without clogging the oil filter. The composition of the oil ensures a reduction in fuel consumption and reduces the amount of smoke emissions. The oil has a very low evaporability, which allows it to be used at any time of the year.

3 Motul Suzuki Marine 4T SAE 10W40

Semi-synthetic oil, created specifically for the Suzuki series of outboard motors. It is distinguished by the clarity of the working conditions of these developments, so the limits of applicability and adequacy of use with other models of powertrains should be felt, as they say, on personal experience. Fortunately, no one forbids this.

According to users, purely technical Motul Suzuki Marine 4T SAE 10W40 is no different from the standard series of oils of the same company. Any composition with a viscosity of 10W40 shows approximately the same results, however, it is not much cheaper than premium development for branded motors. Of course, no one cancels the outstanding parameters for combustion, environmental friendliness and economy, but behind all this a well-planned commercial move is felt, which caused a certain coldness of domestic consumers. Well deserved third place.

2 Quicksilver 4-Stroke Marine 10W-30

Quicksilver 4-Stroke Marine 10W-30 is an interesting semi-synthetics, which became widespread first in America and then moved to the domestic market no less effectively. The uniqueness of this oil lies in the specific requirements for use. While in automobile engines lubrication of friction parts occurs under the action of high pressure, in boat engines oil is delivered only by spraying (which is facilitated by the presence of a immersion ring on the shaft). In such conditions, for unobstructed lubrication, the technical fluid must be sufficiently low viscosity to ensure spread even at low rotational speeds. And Quicksilver 4-Stroke Marine 10W-30 copes with this task, perhaps, better than the others.

This oil is relatively inexpensive, which makes it very popular.However, there is another kind of problem here: since the company is small and the output is limited, it is very difficult to find its products outside dealerships and official distributors.

1 Motul Outboard Tech 4T 10W30

The undisputed leader of the rating is another representative of the company Motul, who has recorded not only outstanding technical and operational, but also price indicators. To challenge his leadership is at least foolish: one pouring of oil is enough for a long time, there is no intensive carbon during combustion, and the cost of four-stroke semi-synthetics is not much higher than that of two-stroke ones.

Another feature of Outboard Tech 4T 10W30, which is so loved by users, is the complete safety of mixing oils of various kinds. This composition can be mixed with mineral or pure synthetic oil in any proportion, and this in no way affects the functioning of the motor.

In general, Outboard Tech 4T 10W30 can be considered the flagship of not only a single series, but also the entire motor oil market in the segment of special equipment, the benefit of all the prerequisites for this to face.
