Each of the five elements circulates through the engine like blood.
There is a question as to whether the sooner the replacement cycle, the better, but there is an issue of adaptability, and replacing it too soon can actually damage the engine.
It is a good idea to wait about halfway through the manufacturer's recommended replacement period before deciding when to replace the filter.
You may have seen people recommending you flush the oil because it's very dirty, or try some additives, showing you their blackened oil. However, as long as it hasn't been changed for a long time and there isn't any sludge buildup, there's no problem if you just change the oil normally.
When we say dirty, we mean that the oil is black, but this does not necessarily have a direct relationship to oil deterioration; in fact, it is normal and it is impossible to judge this by appearance.
If the oil smells like fuel, feels runny and not sticky when you run your finger through it, or is very sticky, has lots of booger-like residue stuck to it, or is cloudy, then something is wrong.
Draining alone will not remove all the oil, so while you're there, check to see if the strainer is clogged and clean it.
Drain gaskets are generally replaced, but metal gaskets rarely leak oil even if they are not replaced.
It is recommended that you replace the O-ring as soon as possible.
It takes time for the oil to drop, so adjusting the oil level by relying solely on the level gauge takes time.
We recommend an oil jug that can measure the amount of oil, but you can also use a funnel and measuring device from Daiso.
While we were doing that, the customer returned, so we quickly cleaned up and handed the item over to him.
Since I've stopped using a compressor and switched to an electric impact driver, I have to go to the stand opposite to adjust the air pressure, so I'll prepare a simple electric compressor for next time.
We look forward to seeing you again.
