How to treat the production date of Honda machine filter

Oil filters have a shelf life, usually one to two years. The following is an introduction to the shelf life of the oil filter:

Generally, the production date will be marked at the top. If you really can't find it, or you can't see it, I suggest looking for an insider. However, there are many such situations.

Expand:

1. The shelf life of unopened engine oil is generally 4-5 years. The pollution and deterioration of engine oil storage are mainly caused by the contact between engine oil and moisture, oxygen and impurities in the air, so the unsealed engine oil must be sealed and preserved. Screw on the fuel tank cap immediately after completing the maintenance in the 4S shop or repair shop. It should be noted that the original tin foil film has been damaged and the isolation effect of the remaining cover pad is limited. At this time, you can cover the bottle mouth with a clean plastic film. In order to avoid damage, it is best to fold it in half several times before screwing on the bottle cap, so that the sealing effect is better.

2. The mechanical oil filter has a shelf life, usually one to two years. Because the mechanical oil filter is a wearing part, the frequency of replacement is very high, so it generally does not care about this shelf life, but it will not expire under normal circumstances.
