Over time this will thicken up and also get dirty. The user then has to replace their oil with a new one to keep their engine running. Considering this, if you have not refueled your vehicle’s engine oil then it probably requires a cleanup.

It is usually recommended that you check the state of your engine oil frequently by removing the long pin placed in the cartridge. This can show you the condition of your oil in case it requires a replacement.
