Tips On Buying An Automobile Oil Filter

There needs to be more clarity among car owners concerning oil filters. Everyone from the manufacturer to the installer to the quick-lube guy to the technician at the dealership to the salesperson at the mall has a different take on how to best care for your vehicle. When it comes to changing oil and filters, there is no one-size-fits-all solution. Individuals vary greatly. The roads are in a different state. When it comes to an oil filter, one size does not fit all. Generally, engine dependability improves when solid contamination in diesel and gasoline crankcase oils is reduced. Particle pollution affects wear and dependability, fuel efficiency, lubricant life, and environmental concerns. Regarding filtration, drivers who adhere to the best procedures report longer service life and lower maintenance costs.

A Fine Dust Of Silica Is The Enemy Of Your Engine

Most pollutants that find their way into engine oil are harmful in some way. Among them are liquids and solids that might cause damage, such as water, glycol, gasoline, incorrect oil, dirt, wear debris, etc. Contaminants in the form of solids are often cited as the most dangerous. In terms of global abundance, silicon is second only to oxygen. Natural soils and dust from the landscape are mainly composed of crystalline silica and silicates (varieties of silicon dioxide). Dust (including silica and alumina) from the outside is the most common cause of engine damage. Compared to a hacksaw blade, each common substance is much more challenging. The surfaces of engine components are easier than, say, a hack saw blade.

Airborne sand and dust particles come in a wide range of sizes, shapes, and abrasiveness. The air intake is the primary route for dust particles from the environment to enter a motor. High-quality air filters may trap 99 percent or more dust that would otherwise enter the engine. Those left are the microscopic particles that get past the ventilation system. Up to and including 10 microns in size, they may be found.

Capacity To Retain Dirt

The dirt-holding capacity offers information about service life before going into bypass. At the same time, the particle capture efficiency provides significant hints about the size of particles the filter can collect (and the overall cleanliness of your engine oil). It is crucial if you’re trying a long oil drain without a scheduled filter replacement. It’s especially crucial if you often take your vehicle out on sandy roads, like dirt or gravel. Keep in mind that, unlike with larger diesel engines, there is no sign on a car’s filter to let you know whether oil is flowing through unfiltered. As with the oil change interval, determining when to swap out the filter is mostly a matter of guesswork, which is why a sufficient buffer zone is required.

Pressure And Flow

Concerns about the filter plugging up more easily are a common deterrent to upgrading from a 40-micron to a 10-micron filter for improved pollution management and longer engine life. The flow rate from the filter to a car’s engine is directly related to the engine’s speed since cars employ positive-displacement pumps. Ten to twelve pounds per square inch of diaphragm pressure is where most filters with bypass valves fail (pressure differential in pounds per square inch). At engine idle, the pressure drop through a brand-new filter may be as low as 1 psid (often much less).


There are now just a few high-performance oil filter for automobiles available. Remember that even though the filter’s packaging claims it is deluxe, high-performance, super-efficient, or darn good doesn’t imply it truly is.
