Are Oil Filters Universal?

Oil filters are not universal, but they can be shared within the same vehicle series. Below is a detailed introduction to oil filters: 1. The oil filter element is the oil filter itself. 2. The function of the oil filter is to remove impurities, gums, and moisture from the oil, delivering clean oil to various lubrication points. 3. There are three levels of oil filters: the oil strainer, the primary oil filter, and the secondary oil filter. (1) The strainer is installed in the oil pan before the oil pump and uses a metal mesh design. (2) The primary oil filter is installed after the oil pump and is connected in series with the main oil passage. It mainly includes metal scraper type, sawdust filter element type, and microporous filter paper type. (3) The secondary oil filter is installed after the oil pump and is connected in parallel with the main oil passage. It mainly includes microporous filter paper type and rotor type.
I've been driving for decades, and oil filters are definitely not universal. Each car has different designs, with variations in size, thread interface, and filtration efficiency. I remember once trying to save money by buying a so-called universal one, and after installation, the engine sounded strange. When I took it apart, I found oil leaking out. Turns out the size wasn't a proper match, and the seal was leaking. This component is responsible for filtering impurities to protect the engine. If it doesn't allow proper flow, the oil can't circulate smoothly, leading to wear on pistons and bearings over time. I recommend owners check their manual for the correct part number or input their car's make and year for an online match before changing it—don't learn the hard way like I did. Even older cars need the right filter to run smoothly.
