One of the main factors affecting engine life internal combustion is the quality of engine oil and the timing of its replacement. To understand which oil is better to pour into the engine tiller, you need to be well aware of the specifics of its device and operation.
Specific requirements.
Most modern tillers (tiller rating can be studied in this article) are equipped with four-stroke gasoline engines that do not have an oil pump in their design.
The lower head of the connecting rod, which is a sliding bearing, is lubricated by scooping up the oil with a particular protrusion on the lower cover of the connecting rod, the main crankshaft bearings, the gas distribution mechanism and the piston/piston group are lubricated by the splashes that occur.
Also these engines have an unstable temperature due to air cooling.
Thus, engine oil for 4-stroke tiller engines must meet the following requirements:
- Low kinematic viscosity in a large temperature range is necessary to avoid oil starvation when the engine is heated to operating temperature.
- The use of viscous oils in engines that do not have a lubricant under pressure, can lead to a bully on the surface of the connecting rod neck, followed by enveloping the metal in this place and jamming the engine.
- The stable package of anti-friction and extreme pressure additives allows the oil to retain its properties for a long time during regular heating-cooling cycles during tiller operation.
- The high strength of the oil film is necessary to protect the cylinder-piston group from scoring when the engine overheats during hard work in hot weather.
- The cleaning properties provided by the appropriate additive package must resist sludge deposition and lacquer formations in the engine pan and on surfaces wetted with oil.
- Low coking properties relevant for air-cooled engines, since the oil entering the zone of piston rings, is heated in this place to a temperature of 270-300 degrees.
- The formation of soot will lead to a loss of mobility of the piston rings and a reduction in compression with simultaneous oil over-consumption.
Based on these requirements, it is possible to describe the technical requirements that the oil must meet for 4-stroke tiller engines, so:
- SAE high-temperature viscosity class is not more than 30 in temperate climates, 40. in hot. Low viscosity index. no more than 10W. These requirements are met by common types of oils 10W30, 5W30, 0W30, 5W40, 10W40 (the last two. at temperatures of 30 degrees or more).
- Purely summer options. SAE 30, SAE 40. It is necessary to read the characteristics of the oils carefully: several specialized oils for garden equipment with a viscosity of 5W30 are designed exclusively for winter use.
- The basis of the oil: synthetic or semi-synthetic, as in these ranges of viscosities, mineral oils are practically not found. Also, they have significantly worse stability compared to synthetics and semi-synthetics.
- Some manufacturers of lubricants have a special line of oils for garden equipment on a mineral basis, in this case, cheapness has a downside in the form of the need for frequent replacement.
- API quality class (a complex parameter that determines the anti-friction, extreme pressure and detergent properties of motor oil, as well as many other parameters) is not lower than SG.
It is necessary to understand that all requirements for motor oils for tillers Cayman, Texas, Foreman, Viking, Sadko, Don, Profi, Carver and Husqvarna meet common automotive oils, the only difference may be its consumption and the amount of carbon generated during long-term operation in an air-cooled engine
For this reason, although this material considers specialized lubricants, in the absence of the possibility of purchasing them, it is always possible to use automotive motor oils that meet the requirements described.

Caliber Semi-synthetic SAE 5W30
Winter oil from the same manufacturer on a semi-synthetic basis. A more advanced base allowed the quality to reach an acceptable API SJ / CF standard. At the same time, the manufacturer indicated a rather low flash point. 228 ˚С, which means its high evaporation and, consequently, a considerable consumption for waste.
How much to fill?
Most tillers presented on the Russian market equipped with HondaGX engines, their Chinese clones or similar in design motors Subaru-Robin.
For a single full filling with oil of such a motor, no more than 0.6 litres of fuel will be required. that is why this amount of packaging is popular with manufacturers. powerful modifications of these engines can hold a litre or more of oil.
Some engines, the design of which includes an additional reduction gear, have a separate space for lubrication.
