The best oils for two-stroke outboard motors

Motul Outboard Synth 2T

Rating: 4.9

Motul Outboard Synth 2T

A product developed by the French company Motul, in which special attention has been paid to ensuring the maximum environmental friendliness available for two-stroke engines. Outboard Synth 2T is a pure, ester-based synthetic with a complex of detergents and restorative additives with low surfactants. Actually, in order to silence environmentalists, manufacturers have brought the composition to a rather rigid framework prescribed by the international certificate of quality and safety TC-W3.

An obvious advantage of this synthetic composition is the ability to perform its functions when using fuel mixture in proportions of 1: 100 (1 portion of oil to 100 portions of gasoline). And, if necessary (in the case of high-power motors), work out with mixtures of 1:50. The exhaust associated with combustion is characterized by low smoke, which indicates complete combustion of the oil in the working chamber. And the composition itself, even when oil is thrown out (which is typical for old outboard motors), does not greatly harm the environment – it consists of 85% of biodegradable components. As a result, owners of boats with two-stroke engines have the opportunity to purchase, if not the cheapest, but very high-quality oil, since there is plenty of it on the domestic market.

Advantages

  • very low consumption;
  • high resistance to carbon formation, low smoke;
  • optimal level of protection for outboard motors of increased power and speed;
  • excellent lubricating and cooling properties;
  • 85% of the components are biodegradable.

disadvantages

  • high price.

LIQUI MOLY Marine 2T (5 L)

Rating: 4.8

LIQUI MOLY Marine 2T (5 L)

A quality German semi-synthetic product that got into the rating due to its applicability for lubrication and cooling of high-speed and old two-stroke engines. Despite the truncated set of filler elements, it takes its toll due to extremely thorough cleaning of the oil base, which contains a minimum of impurity fractions and has a homogeneous structure. It is reliably known that the freezing point of LIQUI MOLY Marine 2T is -39 degrees Celsius – this is the best result in the segment, which even looks very excessive.

Due to the stability of the oil film and a large number of neutralizers, this composition perfectly fights against the ingress of foreign components into the engine, such as salt water, condensate, acid-containing gases and other negative environmental factors. It is also worth noting the outstanding cleaning ability, combined with negligible formation of carbon deposits and exhaust smoke. Perhaps the only negative aspect of LIQUI MOLY Marine 2T is the high price, which is leveled out during the use of the oil due to its long working life.

Advantages

  • a large number of neutralizers of harmful environmental factors introduced into the product;
  • low consumption;
  • good cleansing functions;
  • the possibility of mixing with synthetics and mineral oil.

disadvantages

  • quite high price per liter.

Yamalube 2-M TC-W3 RL Super 2-Stroke

Rating: 4.8

Yamalube 2-M TC-W3 RL Super 2-Stroke

Motor oil from Yamaha, the 'golden' age of which is gradually leaving due to the obsolescence of the composition. Yamalube 2-M TC-W3 RL Super 2-Stroke is a typical 'mineral water' with high consumption and good protective properties, not prone to soot and giving minimal smoke. Despite the low cost of acquisition, when applied, it gives costs comparable to the acquisition of real synthetics. This is due, first of all, to the need for increased consumption for the formation of a fuel mixture: despite the assurances of manufacturers that a ratio of 1: 100 will be quite sufficient, users note that the engine is not very stable even at low speeds. In this regard, in practice, the mixture can reach a ratio of 1:50 or 1:25, depending on the power of the unit and the number of working revolutions.

What really pleases consumers about the Yamalube 2-M TC-W3 RL Super 2-Stroke is the shelf life. According to their assurances, the oil does an excellent job with the test of time, without losing its properties from prolonged languishing in a crankcase or canister. Most often, the uneven operation of the outboard motor is associated with a deterioration in the state of gasoline, while the least complaints are presented to the oil.

Advantages

  • low cost;
  • low smoke;
  • low carbon deposits;
  • good stability of work at the required concentration;
  • durability of the composition due to the use of high quality raw materials.

disadvantages

  • gradual withdrawal from the market and the possibility of purchasing only in the networks of an authorized dealer.

PATRIOT Super Active 2T

Rating: 4.7

PATRIOT Super Active 2T

The fourth place in the rating goes to semi-synthetics from the Chinese company Patriot, the main feature of which is its low price. The same feature determines the high demand for the composition in the network of retail stores, mainly among those who have more than a decade of experience in using outboard motors. Jokingly comparing Super Active 2T with autol (mainly for cost), users note the good quality of the oil in the engine cleanliness component after use. Not the most technologically advanced formula with a small amount of additives provides low carbon deposits, but at the same time it is distinguished by high smokeiness, which is why the manufacturer often receives complaints from environmentalists.

According to experts, the key advantage of PATRIOT Super Active 2T is a high degree of versatility: the composition can be poured not only into outboard motors, but also into two-stroke engines of snowmobiles, motor vehicles and other garden equipment, in which it works surprisingly smoothly. Users like this, and therefore the shelves of stores with this oil are emptied quite quickly.

Advantages

  • very low price;
  • low level of carbon deposits on pistons during use;
  • low consumption for the fuel mixture;
  • versatility in terms of serviced equipment.

disadvantages

  • high smokiness due to the combustion of a number of components that make up the oil.

The best oils for 4-stroke outboard motors

MOTUL OUTBOARD TECH 4T 10W30

Rating: 4.9

MOTUL OUTBOARD TECH 4T 10W30

Another representative of the Motul company, developed as a universal compound for outboard and outboard motors. Its creation is based on the unique Technosynthese technology, which takes into account the subtleties of work and design of absolutely all four-strokes on the modern market. The proof of this is the internal tests of developers, as well as independent experiments of experts, which have shown amazing results in terms of preserving the working resource. The second important advantage of OUTBOARD TECH 4T 10W30 is the high resistance of the oil film to tearing under the influence of high temperatures. At 40 degrees Celsius, the viscosity of semisynthetics is 77.8 mm2 / s, while at 100 degrees the indicator does not drop below 10 mm2 / s.

The pour point of the oil is -33 degrees Celsius, and therefore it is not worth worrying about the deterioration of engine performance (except for snowmobiles, but it is not advisable to use them at such a temperature). Ultimately, consumers get not the most expensive semi-synthetics, which have the parameters of a full-fledged synthetic oil, the working conditions of which are more than enough for the season's rollback.

Advantages

  • absolute versatility in terms of serviced four-stroke engines;
  • acceptable price;
  • high stability of the oil film even at elevated operating temperatures;
  • low level of the freezing point of the composition.

disadvantages

  • not found.

MOTUL SUZUKI MARINE 4T SAE 10W40

Rating: 4.8

MOTUL SUZUKI MARINE 4T SAE 10W40

One of the striking examples of semi-synthetic oil for outboard motors, developed in close cooperation with the Japanese concern Suzuki. Accordingly, it works perfectly with the products of this brand, but, as experts say, it shows itself well in other models of four-stroke engines. French manufacturers do not put any restrictions on the use.

From a technical point of view Suzuki Marine 4T SAE 10W40 is the same product in the standard Motul range with slightly improved combustion, emissions and economy. For all this, a special package of additives is responsible, designed to eliminate the characteristic vulnerabilities of engines Suzuki. For the rest, neither in terms of viscosity, nor in retention of the oil film, and even more so in the component of the pour point, there is no particular difference. All this unequivocally leads to the opinion that behind a specialized label lies more of a delicate commercial move than a breakthrough development for the products of a particular manufacturer.

Advantages

  • the completeness of combustion of a portion of oil in the process of fuel ignition is increased;
  • small savings in terms of oil consumption;
  • low carbon deposits;
  • technical characteristics at a high level.

disadvantages

  • practically the same basic indicators as for semi-synthetic oils of the standard series;
  • high price.

QUICKSILVER 4-STROKE MARINE 10W-30

Rating: 4.8

QUICKSILVER 4-STROKE MARINE 10W-30

Mineral motor oil of American production, which first received recognition among consumers in its country, and then conquered an already saturated segment of the Russian market. The beauty of Quicksilver 4-Stroke Marine 10W-30 is that it has a high viscosity, but is easily sprayed around the chamber by means of the immersion ring on the crankshaft. Moreover, spraying is ensured even at low rotational speeds, which makes the oil especially valuable when used in orderly worn out motors with a high percentage of the exhausted resource.

According to the experts, Quicksilver 4-Stroke Marine 10W-30 perfectly matches the outboard motors from Mercury, taking into account every nuance of their work and trying to influence it from the outside. However, all this is purely advisory in nature. The oil itself is quite cheap, which causes high demand among consumers. But, a problem of a different kind comes to the surface: due to the current situation in the world and the limited nature of the product, it is not possible to find it on the market. The only exceptions are dealerships and shops of the company's official distributors.

Advantages

  • good performance in the component of work with worn out engines;
  • optimal formula for good oil dispersion while maintaining high viscosity;
  • low price.

disadvantages

  • low prevalence in retail.
