Most Japanese motorcycles are operated exclusively in the summer season, staying in a warm garage for the winter.
That after a long winter parking there were no problems with the engine, it is necessary to apply quality oils for the motorcycle.
There are many rules to help you chooseThe right oil to the motorcycle. One of the main - to fill only what is recommended by the manufacturer and is written in the operating instructions or in the service book.
Oils for old and modern motorcycles
If the motorcycle is old - the 80's of release orOlder - it can be "fed" and motor oil. The fact is that standards for lubricants for motorcycles began to be developed in the 80s, and many motorcycles of those years were designed to work with automotive oils. Moreover, many owners drive exclusively on mineral oils. For older, air-cooled motorcycle motors, SAE 50 mineral car oil is an ideal choice both in terms of product stability and in terms of benefits.
When switching from one oil to another, when refueling a motorcycle with low-quality gasoline, if the engine overheats or the oil change term is exceeded, the engine must be washed before refilling the new oil.
For a modern motorcycle, the oil must containCertain additives, have a certain viscosity and be calculated for operation at high temperatures and engine speeds. Motorcycle oil, unlike automobile, is less ashy, neutral with respect to acidity and alkalinity, does not have harmful effects on aluminum parts.
Japanese motorcycles have an engine, gearbox,Motor transmission, and sometimes the generator is lubricated by the same oil. Therefore, the use of low-quality oils is extremely harmful for all these units.
Most manufacturers of Japanese motorcyclesRecommend the use of synthetic oils, as they do not leave deposits and coke in the engine. In this case, synthetics can be made both on the basis of esters and on the basis of polyalphaolefins. Synthetic oils based on esters are used for racing motorcycles and require replacement after each race. Materials based on polyalphaolefins have weaker protective functions, but are well suited for everyday and long-term use.
Oil viscosity parameters
Also many Japanese motor-car manufacturersPrescribe in the instructions application of low viscosity oils, which protect the motor of the motorcycle well at peak loads. However, many experts recommend in Russia to use more viscous oils for Japanese motorcycles. The more severe road and climate conditions of our country are very different from European and Japanese. More dense lubricants better protect the motor from overheating and under high loads. This opinion is equally true for both low-rugged and highly-engineered Japanese motorcycles. When choosing a particular product, pay attention to the numbers in the designation of the viscosity standard. The first figure in parentheses is the viscosity of the oil when the engine is cold starting. This parameter is important for those who use a motorcycle in sub-zero temperatures. The second figure is the viscosity of the oil at high temperatures. The higher its value, the thicker the oil.
