Synthetic multigrade oils (light-moving)
The easy-running oil is a multigrade oil that has a special additive that reduces the coefficient of friction, which helps to reduce fuel consumption by up to 2%. Easy-stroke oil has a low viscosity (e.g. 10W-30). This oil is synthetic based. The use of the specified oil must be approved by TOYOTA.
Applications and oil viscosity grades
Gas engine
Diesel
From the graphs in Fig. G-1601. and G-1602, it can be seen that the areas of application of SAE oils of neighboring classes intersect. Therefore, a short-term change in the operating temperature of the oil that goes beyond the recommended temperature range should be considered acceptable. It is also allowed to mix oils of different viscosity classes with each other. If necessary, refuel the engine with oil of a different viscosity.
Lubricating additives of any kind must not be introduced into the fuel or oil.
Engine Oil Specifications
Modern engines use only HD oil. HD-oil is an alloyed oil, the lubricating properties of which are significantly improved due to the introduction of special alloyed additives. These additives improve the anti-corrosion properties of the oil, increase the resistance of the oil to oxidative processes and slagging in the oil pan, help stabilize the viscosity, increase its cleaning and dissolving properties. Cleaning and dissolving additives not only reduce the formation of deposits in the engine, but have the ability to dissolve deposits, crush and keep them in suspension, which makes it easier to remove them during the oil drain process.
The quality of engine oil is determined by the API system (American Petroleum Institut). European oil manufacturers are also guided by this system.
The designation according to the API system consists of two letters. The first letter indicates the field of application of the oil: S=Service, designed for carburetor engines, C=Commercial, designed for diesel engines. The second letter indicates the quality of the oil in alphabetical order.
Oils with the API designation SG for carburetor engines and CE for diesel engines have the highest quality. Attention: Engine oils intended for diesel engines should not be used for carbureted engines. There are oils that can be used for both carburetor engines and diesel engines. In this case, the oil contains the corresponding designation, (e.g. SF/CD).
API specification oils are used for gasoline engines. having the designations SE, SF and SG, oils with the designations CD and CE are used for diesel engines.
Oil consumption
Under the oil consumption in an internal combustion engine, one should understand its amount that burns during the operating cycle. Oil consumption should not be confused with oil losses due to leaks in the oil pan, cylinder head, etc.
Oil is consumed as a result of its combustion in the engine cylinders, entrainment with exhaust gases and friction products. This does not include oil losses due to high temperatures and pressures that occur during engine operation.
The oil consumption is also affected by the operating conditions of the car, driving style, and technological tolerances of engine elements. Oil consumption should not exceed 1 liter per 1000 kilometers.
Oil should be topped up when it reaches the mark "Nachfull" (Topping up).
Attention: Do not fill in a lot of oil at once. If too much oil is poured into a vehicle equipped with a catalytic converter, the excess oil must be drained as it can enter the exhaust system and destroy the catalytic converter.
