Do I need to change the engine oil if I don't use my car for a long time? What should I do if the oil dipstick turns black after a long time of not using the car?

Since the Spring Festival, many people have been staying at home due to the virus, and their cars have not been driven much. Some people have found that the oil dipstick has turned black and the vehicle cannot be driven out, but it does not mean that the vehicle cannot be started. So there are still ways to minimize the loss of the vehicle. Let's take a look at how to solve it!

Do I need to change the oil if I don't use my car for a long time?

If the vehicle is parked for a long time and the engine oil is dark in color, car owners do not need to worry too much. Regular engine oil does not mean that it will be completely ineffective after reaching a certain mileage. The engine oil used for a long time will only reduce its ability to clean the engine and lubricate, which does not affect our short-term use. The darkening of the vehicle's engine oil is mainly because the engine oil undergoes oxidation reaction under high temperature conditions, and the function of the engine oil is to clean the inside of the engine. The blackening of the engine oil indirectly reflects that the engine oil has good cleaning ability.

Practice: If the vehicle has been parked for a long time and prompts that the oil needs to be changed, we don’t need to be nervous at this time. Just check whether the vehicle’s oil level is in the middle of the oil dipstick scale line. If the oil level is normal, the vehicle can be started directly and driven to the auto repair shop to change the oil.

What to do if the oil dipstick turns black after long-term non-use

It is normal for the oil on the dipstick to turn black. Due to the impact of the epidemic, most 4S stores may not resume work until mid-February. So you can judge for yourself first. 1. Ordinary oil needs to be replaced within 5,000-7,000 kilometers and 6 months. Semi-synthetic oil needs to be replaced within 8,000 kilometers and 8 months. Fully synthetic oil needs to be replaced within 10,000 kilometers and 12 months. 2. Check the oil dipstick to ensure the right amount of oil.

When should I change the oil if I don't use my car for a long time?

Generally speaking, the engine oil will not be so clear and bright after being added to the engine for a period of time, especially for diesel engines. Just after changing the oil, the oil will turn black after you idle for a few minutes. Because the oil not only has a lubricating effect, but also has a cleaning and dispersing effect. The oil turns black because it dissolves and disperses the impurities in the engine. If the oil is still clear and bright when you change the oil, it will be troublesome. So don't worry.
