【Meiruier Filter】Does it matter if the oil grid is not changed?

2022-06-28 View:

Not changing the oil level at one time has an impact. If you only change the oil without changing the oil grid, the effect of filtering the oil will not be achieved, and there will be more and more impurities in the oil, which will affect the power and life of the engine. Because the old oil compartment contains a lot of iron filings and colloidal debris, and there will be more and more, it will block the filter holes of the filter paper, seriously affect the oil passing ability, and inhibit the oil lubrication, cooling and other functions. There is no problem in the short term, but it will damage the engine for a long time.

The effects of not changing are:
1. Because the old oil boom contains a lot of iron filings and colloidal debris, and there will be more and more, it will block the filter holes of the filter paper, seriously affect the oil passing ability, and inhibit the oil lubrication and cooling functions. There will be no obvious problems in a short time, and the engine will be damaged in a long time

2. If the old oil chamber is not replaced after the oil change, the old oil containing impurities will be added to the circulation of the new oil, polluting the new oil and reducing the quality and effect of the new oil.

Maintenance routine:
1. Change the oil filter every 100~200 hours (5000~10000 km).
2. When installing a new spin-on oil filter, first apply a thin layer of oil on the surface of the sealing ring, and then tighten the filter by hand but not more than 3/4 turn. If you are not sure, you can also start the engine and run it for 2 to 3 minutes to see if there is any oil leakage.
3. The oil grade is as specified in the instructions. If there is no information, use 40CD engine oil for diesel engine and 30SC or SD, SE grade engine oil for gasoline engine.
4. Check the oil dipstick (oil level) every week. Check the oil color and thickening and thinning.
5. When the engine is running, always pay attention to the oil pressure. If the oil pressure is too low, you can replace a new oil filter and start the inspection. If it is still too low, check the engine, and the filtration efficiency of the oil filter must be guaranteed to reach 70%.
