Why are some oil filters bigger than others?

All things being equal, a larger filter has two key benefits – 1) more oil capacity in the system, which helps extend useful life, and keep temperatures down, 2) more filter area means greater dirt holding capacity and therefore greater filtered flow for longer, before filter media saturation and bypass valve actuation …

Are all oil filters the same fit?

You will want to check with your vehicle’s manufacturer to make sure, but typically any automotive filters that are made for modern vehicles can be used with any type of oil. Every major motor oil manufacturer says you do not need a special or different oil filter when using synthetic oil.

Will the wrong oil filter fit my car?

Using the wrong oil filter can negatively impact oil pressure. If the relief valve is damaged, or the wrong filter is used, too much or too little oil can pass into the engine. Using the wrong oil filter may prevent the filter from sealing properly, leading to problems with oil pressure or leaks.

How do I know my oil filter size?

How to Find an Oil Filter by Sizing

1. Remove the oil filter and drain the oil into a catch pan. Use a ruler to measure the diameter of the screw hole on the old filter.
2. Measure the diameter of the filter. This will include the sealing area of the filter.
3. Measure the height of the filter.

Why are oil filters small?

Obviously, a small micron-size oil filter is associated with lower wear rates and prolonged engine life (more on this later). The filter must also be able to remove particles fast enough to keep up with the rate new particles arrive into the oil (ingression rate).

Do oil filter sizes matter?

Are low-quality oil filters bad for your car engine?

While the benefits of clean oil are significant, low-quality filters are frequently specified for automobile engines. Consider this, according to a study by one engine builder, particles smaller than 10 microns generated about 3.6 times more wear (rods, rings and main bearings) than particles greater than 20 microns.

Are oil filters all the same?

To many people, oil filters are a generic product. Price is the only factor considered when they choose a filter. They do look pretty much the same on the outside, but what’s inside can make a big difference. Filter manufacturers use a variety of different filter media to keep the oil clean.

How many microns is too small for an oil filter?

Consider this, according to a study by one engine builder, particles smaller than 10 microns generated about 3.6 times more wear (rods, rings and main bearings) than particles greater than 20 microns. Typical automotive oil filters remove particles 40 microns and larger.

Why do different engine sizes have different oil types?

Different manufacturers have different standards for flow capacity, filtration, backflow valves, etc. A large engine will need more flow capacity than a small engine. They also don’t all use the same viscosity oil. Joe-Guy
