| Motor Vehicles Service How to choose the right motor oil for motorcycles? A variety of abbreviations for banks with oils are not tempted to put the owner of the iron horse to a standstill.
Moto-oil does not have a special classification. Therefore, the scope of their application in the manner indicated by car.
 So there are two parameters that determine the merits of an oil producer. This level of quality and strength. For four-stroke engines are most suitable SAE, which developed the technology of American engineers.
viscosity motor oils and temperature
There motorcycle engine oils that are used to run the engine in just a cold, or only in the hot season of the year. But now it is more common to find all-season oils with double tagging. It is clear that the use of the motorcycle in sub-zero temperature of the air will be the exception rather than the rule. But for many, and this information will be of interest.
Winter series of oils - SAE 0w, 5w, 10w, 15w, 20w, 25w. Not the fact that manage to find it on sale.
oils that are designed for use in the warmer months, is also on sale can be found with great difficulty. They are designated marking: SAE 20, SAE 30, SAE 40. Oils which have a SAE viscosity of more than 60 belong to the class of transmission. In the motors do not use them.
multigrade oil is obtained by adding a simple little thing, which is the foundation, special additives, after which the oil is pretty thin. With such a small engine will be easy to start even if the air temperature drops below zero degrees Celsius. Additives excellent protection friction parts of the engine, at a time when it is heated.
-season types of oils indicate so: SAE 10W40, 10W60, 10W50, that is, those combinations of numbers that define the temperature ranges of a particular type of oil. The number which is preceded by the letter W is a negative temperature at which the oil thickens. The number that comes after this letter, is the highest temperature at which the oil will work well.
approximate range of temperatures and labeling of oils:
SAE 0W-30 -30 to +20 degrees Celsius
SAE 0W-40 -30 to +35 degrees Celsius
SAE 5W-30 -25 to +20 degrees Celsius
SAE 5W-40 -25 to +35 degrees Celsius
SAE 10W-30 -20 to +30 degrees Celsius
SAE 10W-40 -20 to +35 degrees Celsius
SAE 15W-40 -15 to +45 degrees Celsius
SAE 20W-40 -10 to +45 degrees Celsius
level of the oil.
In viscosity engine oil for motorcycle must have different properties. So it's okay to stick to the running gear (do not dry friction), to be quite liquid at cold start (in order to avoid jamming of the engine), to prevent overheating and warping of parts (cool them), have detergent properties for the motor (to remove carbon deposits and debris ), to protect the engine from wear and tear, do not let escape into the environment of a large Number of harmful emissions. Virtually all the oil in the combined classification of API (American Petroleum Institute).
There are two categories of classification API:
- S for petrol engines (SE, SF, SG, SH, SJ, SL)
- C for diesel engines (CC, CD, CD, CF, CG, CH, CI)
The first letter stands for the labeling of oil. The second - a level of quality (performance characteristics). An older character (after the start of the alphabet) points to a more modern oil.
SE - petrol engines 1972-1980 years
SF - petrol engines 1981-1988 period. Cleaning and anti quality of the oil is higher.
SG - for most gasoline engines from 1989. Detergents and anti-wear properties of the oil are even higher. The oil was noticeably prolong the life of the engine.
SH - class is similar to the SG. Introduced in 1993. Different - the more demanding tests of oil.
SJ - introduced in 1996, with stricter requirements for emissions of harmful substances into the atmosphere.
SL - class introduced in 2001. The most demanding of fuel efficiency, anti-wear properties and kollichestvu vrednh vybosov class. Also introduced strict requirements for the duration of the oil. More stringent test requirements and oils.
classification of oils ACEA
In evroppe has its own classification quality oils - ACEA. In this classification, the oils more demanding than in the API. This classification is very similar to the car classification in the euro area.
All oil in this category is divided into three types:
- A - petrol engines (A1, A2, A3 and A5)
In - - low power diesel engines fitted to cars and trucks low power (B1, B2, OT, B4 and B5)
- E - diesel engines for heavy vehicles (E1, E2, EZ, E4, E5 and E7).
Chemical type oils
The chemical origin oils differ, so as to road and third type:
- Mineral - obtained by the distillation of crude oil. Physical and chemical properties of these oils are highly dependent on the quality of the oil from which they are made. Therefore, different parties oils of the same manufacturer may be slightly different in their characteristics.
- semi-synthetic - a mixture of mineral and synthetic oils. Specifications well as directly dependent on the quality of the components. Under the rules, a semi-synthetic oil can be called only if its composition contains at least 25% synthetic base. Unscrupulous manufacturers can cheat, posing for a "semi-synthetics" oil containing synthetic base only 5% -10%. Be careful when buying a semi-synthetic oil, and always read the label.
- Synthetic - produced entirely by chemical means. They include glycol ethers or poly-alpha olefins. It is believed that they are better Mineral oils as heating are better, more resist oxidation and have a higher viscosity index. The performance characteristics of synthetic oil is better in all respects, except for aggression to rubber parts.
