These days, there are all kinds of oils in the market and each seller offers you a specific oil, but motor oils that are suitable for motorcycles produced in Iran, respectively, SE and SD quality based on API standard and performance and price are different. Keep in mind that it is best to use 10w / 40w best motor engine oil in winter and 20 w / 50w in summer. Our company has the best motor oil, which sells this product at a wholesale price.
How long can you drive without oil?
Most drivers do not think about how many times to change the oil in the engine. They follow what is written in the manual (every ten to fifteen thousand kilometers).
However, you also need to consider how the vehicle is running and what lubrication is being poured into the engine. Drivers must be able to calculate the optimal frequency for oil change.
It is worth noting that changing the engine oil in the engine, considering only the mileage of the car, is not very logical. With the same distance traveled on the highway and in the city, the difference in engine hours will be more than 4 times. The degree of deterioration of the properties of the oily liquid will also vary. For example, at a typical 15,000-kilometer distance in traffic, oil runs seven hundred hours, and on the highway less than hundred.
This is a big difference, because even with a small load, the effect of temperature on consumption is enormous. In ICE today, the situation is exacerbated by rising temperatures, poor tire ventilation, and a lack of cooling in traffic vehicles. This leads to a rapid reduction in the operating period of the oily liquid.
Along the way, the load can also vary. When driving at a maximum speed of 100-130 km / h in most cars, the load per unit of power is below average \ u200b \ u200b. The temperature is low, and the crankshaft is normally ventilated. In high-powered engines, the load is minimal, so the breakdown of oil properties passes very slowly.
Also know that in designing an engine oil selector system (motorcycle engine, car, motor boat, electric motor, etc.) in which the lubrication operation is performed by engine oil, has very accurate calculations of the empty space between the parts (empty space between The piston and cylinder, the empty space between the gearbox gears, the empty space between the bearings under the connecting rod and the crankshaft, are filled with oil, which in addition to reducing friction, causes precise matching or so-called sealing. The amount of these voids is calculated and designed depending on the volumetric density of the oil.
Important Features of the best motor engine oil
Among the important features of the best engine oil
API factor (in terms of quality:
The American Petroleum Institute (API) index, as defined by the American Petroleum Association, represents the quality standard of engine oil. This indicator is marked with 2 English letters on the engine oil bottle. Most automakers use SN, SM, SL, SJ standards in their engines, among which SN, SM has the highest quality among engine oils. In fact, the car company a specific API standard for the engine according to the needs of the car, for example SM, which, of course, with the advancement of science and technology, especially in the field of engine oil, it is reasonable to use the higher SN standard.
Types of engine oil
Engine oils are divided into three main groups: mineral, synthetic and semi-synthetic, and their main difference is in the method of production and the elements used in their construction. Today, synthetic and semi-synthetic oils are more widely used. Engine oils are supplied with two numbers and one letter w. The other two numbers indicate the minimum and maximum viscosity of engine oil in different temperature conditions, and most importantly, whether engine oils are generally or suitable for gasoline engines, or diesel or turbocharged, which you choose depending on the type of car. . For example, engine oil is suitable for Pride and Nissan engine oil is different.
