How to Identify the Model of an Oil Filter?
2 Answers
The model of an oil filter can typically be found on the outer casing of the filter, which usually includes the manufacturer's part number, or you can refer to the vehicle's maintenance manual. The functions of an oil filter include the following points: 1. During engine operation, metal shavings, dust, carbon deposits oxidized at high temperatures, colloidal deposits, water, and other contaminants continuously mix with the lubricating oil. The oil filter's role is to remove these mechanical impurities and colloids, ensuring the cleanliness of the lubricating oil and extending its service life. 2. The oil filter, also known as an oil element, comes in two types: full-flow and bypass. A full-flow filter is connected in series between the oil pump and the main oil gallery, filtering all the lubricating oil entering the main gallery. A bypass filter is connected in parallel with the main oil gallery and only filters a portion of the oil delivered by the pump.
As an experienced driver who has changed many oil filters, I usually determine the model by checking the label on the old filter. It's typically located on the side or top and consists of a combination of numbers and letters, like PH4967. I once bought one without checking, only to find it didn’t fit, wasting my time. Now I’ve learned to take a photo of the label and save it on my phone. The car manual also lists recommended models in the maintenance section—handy for backup. When shopping online, entering the car’s make and year can auto-match the correct model, which is quite reliable. But remember, using the wrong model can restrict oil flow and damage the engine, so always double-check before each replacement to ensure smooth oil circulation.
