Operating a two-stroke outboard motor on water requires special attention to the quality of lubricants, since the engine life and its reliability directly depend on this.
Choice Ravenol 2T oil It is often the best solution for owners of Mercury, Tohatsu, Yamaha and other popular brands looking for a balance between price and protection.
In this article, we will discuss in detail why German chemistry is trustworthy, how to mix the fuel mixture correctly and what mistakes should be avoided when servicing your home. outboard motor.
Why the TC-W3 specification is critical for outboard motors
Two-stroke engines installed on boats operate in fundamentally different conditions compared to chainsaws or motorized blocks.
The main difference is in the lubrication system: the oil burns with the fuel, so it should not only reduce friction, but also completely burn, leaving no sticky deposits on the piston group.
Standard TC-W3 Two Cycle Water cooled, developed by the National Marine Industry Association (NMMA), is a strict certification to ensure that the product has passed tests for corrosion, scalding and lubricating capacity in an aquatic environment.
The use of oils that do not have the TC-W3 marking, for example, intended for motor vehicles (JASO FC / FD), can lead to rapid occurrence of piston rings and overheating.
Products RAVENOL fully complies with these stringent requirements, providing reliable protection for crankshaft bearings and rod fingers even with prolonged operation at high revs.
In addition, special additives prevent rusting of parts when a simple boat in the off-season, which is especially important for freshwater reservoirs.
⚠️ Warning: Never use car oils or oils for four-stroke engines in a two-stroke engine tank, as they won’t burn out completely and will cause the exhaust system to coking up in one season.
Technological advantages of RAVENOL Marine 2-Takt Oil
German engineers have developed a formula RAVENOL Marine 2-Takt Oil taking into account the specifics of work on ethanol-containing fuels, which are becoming more common.
One of the key features is the high thermal stability, which allows the oil to maintain its properties at combustion temperatures above 300 degrees Celsius.
This prevents the formation of so-called "varnish" on the bottom of the piston, which is the main cause of potassium ignition and detonation.
Another important aspect is the low exhaust smoke.
When working RAVENOL 2T The smoke becomes almost transparent, which reduces water and air pollution, and minimizes the formation of soot on spark plugs and a silencer.
The composition includes high-quality base oils and a package of additives that provide excellent mixability with gasoline of any octaneity.
When storing a boat for more than a month, be sure to add a fuel stabilizer to the fuel tank, since modern gasoline with ethanol can layer and accumulate moisture.
It is worth noting that the oil has excellent anti-corrosion properties, creating on metal surfaces the thinnest protective film.
This is especially important for boat owners who store equipment in water or in high humidity conditions.
Regular use of high-quality lubricant prolongs the life of obble oils and seals, preventing their drying and the appearance of compression leaks.
Proper proportions of mixing of fuel mixture
One of the most common questions owners are the ratio of gasoline and oil.
For most modern two-stroke engines produced after 1990, the standard is 1:50 (2% oil per volume of gasoline).
However, for older models or engines with higher power (over 50 hp), manufacturers may recommend a 1:40 or even 1:33 break-in mixture.
Accurate adherence to the dosage is critical: excess oil will lead to soaking and a decrease in power, and the lack of it will lead to bullies in the cylinder and engine wedge.
Oil RAVENOL Due to its high concentration of active substances, it allows you to comply with the proportions recommended by the manufacturer of the motor without the risk of underlubrication.
For convenience of calculation always use measuring capacity with risks, and do not pour "by eye".
Mixing should be done in a separate clean canister, and not pour components directly into the engine tank.
First pour half the required volume of gasoline, then add the entire portion of oil, shake thoroughly and add the remaining gasoline.
The thawing sequence ensures homogeneity of the mixture and uniform distribution of lubricating components throughout the fuel volume.

Comparative table of oil specifications for 2T engines
To better understand the place RAVENOL 2T In the lubricants market, it is worth comparing its key parameters with competitors and industry standards.
This comparison will help you make an informed choice when buying a canister before you start navigation.
| Parameter | RAVENOL Marine 2-Takt | Mineral (mineral) | Synthetic (Synthetics) | NMMA TC-W3 Standard |
|---|---|---|---|---|
| Basis | Semi-intelligent | Mineral | Synthetic | Anything. |
| Flash temperature | High (>200°C) | Medium | Very high. | Normalized |
| Nagara education | Minimum | High. | Missing. | Permissible. |
| Storage period of the mixture | Up to 6 months. | 1-2 months | Up to 12 months. | Depends on the base. |
| Price/Quality | Optimal. | Low. | High. | Basic |
As you can see from the table, a semi-synthetic base RAVENOL It is the middle ground.
It provides protection close to synthetics, but is cheaper, while significantly superior to mineral oils in the purity of combustion.
For amateur fishing and cruising skating, this is the most rational choice.
Semi-synthetic oils such as RAVENOL provide better protection against corrosion and soot compared to mineral counterparts, while remaining affordable for most boat owners.
The effect of oil on the operation of the cooling system and candles
Many people forget that in a two-stroke engine, oil is involved not only in lubricating the KSM, but also affects the state of the exhaust and cooling system.
The combustion products of poor quality oil can clog the water channels of the cooling shirt, especially in the area of the exhaust windows of the cylinder.
This leads to local overheating and deformation of the cylinder head.
Use of use RAVENOL 2T Minimizes this risk by completely burning the oil base.
The spark plugs stay clean much longer, keeping the correct spark gap and nagar color (brick brown).
If you notice a black oily coating on the electrodes, this is a signal of an incorrect proportion of the mixture or a low quality of lubricant.
⚠️ Warning: If the candles become whitish after changing the oil to a better quality, this may indicate a too poor mixture or the need to adjust the carburetor, rather than an oil problem.
The cleanliness of the exhaust system also affects environmental friendliness and comfort.
Oils with poor evaporability create thick blue smoke that settles on the transom of the boat and the clothes of fishermen.
RAVENOL This is a disadvantage, making the water more pleasant.
Seasonal Storage and Conservation of the Motor
The winter storage period is a critical time for the outboard motor.
The mixture left in the carburetor and fuel system loses its properties during the winter: gasoline evaporates, and oil precipitates.
For proper preservation, you need to develop the residues of fuel or drain them, then start the engine with a new portion of fresh mixture.
It is recommended to use a mixture with a slightly higher oil content (e.g. 1:40 instead of 1:50) for the last run to create a protective layer inside the cylinder.
Oil RAVENOL 2T Due to its anticorrosive additives, it perfectly copes with the task of preserving internal surfaces.
Don’t forget to also blow out the carburetor and fuel hoses to prevent moisture from getting in.
Do I need to drain the oil from the gearbox for the winter?
Yes, it's a mandatory procedure. Even if the gearbox has a branded oil, it could get moisture through the glands during the season, water will expand when it freezes and can damage the body or the glands, and replace the oil with fresh oil before wintering.
Store a canister with oil residues in a warm room, avoiding direct sunlight and sharp temperature changes.
The density of the package should be ideal to exclude moisture and oxidation of the product.
If you follow these simple rules, your engine will start easily in the spring and last for many years.
Frequently Asked Questions (FAQ)
Can I mix Ravenol 2T oil with other brands?
Technically, oils on a similar basis (mineral with mineral, synthetic with synthetics) are mixed, but manufacturers do not recommend this.
Other packs of additives can enter into a chemical reaction, which will reduce the protective properties of the mixture.
It is better to completely develop the old oil before switching to a new brand.
What is the shelf life of an open canister with RAVENOL oil?
In a sealed factory container, the storage period is up to 5 years.
After opening, it is recommended to use oil for 2-3 years, subject to tight closure of the lid and storage in a dry place.
If the oil is clouded or there is a sediment, it can not be used.
Will this oil be suitable for outboard motors of Chinese production?
Yeah, RAVENOL Marine 2-Takt Oil It is universally suitable for any two-stroke water-cooled engines, including Chinese brands (Hidea, Sea-Pro, Parsun).
Chinese engines often have less accurate tolerances, so the quality of lubrication is even more important for them than for Japanese counterparts.
Why can’t you use a regular two-stroke oil for chainsaws in a outboard motor?
Oils for air cooling (chainsaws, trimmers) have a different composition of additives and are not designed to work in an aqueous environment.
They are worse at protecting against corrosion and may form more scoop at low revs typical of trolling.
Using the wrong oil can lead to a quick failure of an expensive outboard motor.
