First we can be divided into two parts to discuss, one is just bought a new car, is still in the running-in period, we should change the oil how often, the other is after the run-in period of how often to change the oil!

The running-in period

Motorcycle and car oil is roughly the same, are divided into mineral oil, or synthetic oil. No matter what kind of oil? The final purpose is to ensure the engine lubrication, and play a role in heat dissipation, so the oil is the same as the engine blood, to pay attention to its quality. For the car still in the running-in period, the proposal still wants according to the standard, the details can refer to his motorcycle instruction manual.

At present, the motorcycle oil change standards are more generally recognized in the new car before 1000 km run-in period standards are 300, 600, 1000 km incremental replacement

When the new car changes oil for the first time, it is best to clean the oil filter, because the motorcycle wears down more iron filings

Outside the period

Running-in period generally arrives 1000 -- 1500 kilometers almost gave running-in period, gave running-in period according to normal driving condition the cycle of change oil is every 2000 kilometers change, but the performance of each car is different, what two flusher is gasoline and oil mix burn. Four strokes are lubricated and do not participate in combustion. A typical motorcycle should be a four - punch.

If burning oil, it is recommended to go to the repair shop immediately to check: cylinder block, piston, piston ring, valve and oil seal. The oil is very dangerous to dry, easy to explode cylinder, if the cylinder, your engine is almost scrapped more than half, must frequently check.

A special case

The performance of each car is not the same, driving environment is not the same, different circumstances under the change of oil frequency is not the same!

1, the car driving environment is better, do not need to climb regularly. The road is smooth, not heavy, not frequent shift start and stop, the driving operation specification of the rider (not often hit the throttle) can be changed according to the normal cycle or extended a little cycle replacement.

2, the vehicle driving environment is bad, often need to climb the slope, driving the road is more rugged, or frequent short distance start, load belt people driving, so that it belongs to the working condition of the bad category, the need to change the oil in advance, of course, the oil change point is certainly good for the vehicle!

3, the viscosity of oil at high temperature has a big change, it is generally believed that 100℃ kinematic viscosity value deviation more than 20%, must be replaced!

Reason for oil change

The main reason why we have to change the oil per certain mileage is:

1, the oil's dispersion performance decline, can not dissolve the engine work process produced by the carbon!

2, the oil is acidic, contains a lot of acid oxide, easy to corrosion parts!

3. There are metal particles in the oil, which aggravate the wear of the parts in operation (the filtering effect of the filter structure is not complete enough)!

4. The oil flash point decreases, which affects the safety. This is because frequent cold starts may cause the gasoline to cascade through the ring gap into the crankcase. National standards, gasoline oil flash point value must not be lower than 210℃!
