Know Oil Filters Inside Out – Auto Service World | CarTailz

All vehicles are equipped with various filters to keep fluids and air in optimal condition for the driver.

The typical vehicle has at least a pollen/cabin filter, a fuel filter, an air filter, and an oil filter.

A good automotive service and repair facility will instruct the vehicle owner to replace the filters when the time comes.

But explain why? And give them the information they need to understand that not all filters are created equal – the value can vary significantly. Not to mention that it can be difficult to spot an inferior filter with the naked eye.

The COVID-19 pandemic is shedding light on the importance of air quality in vehicles. Consumers are now more wary of slipping a clogged filter. With the growing awareness of filters and their maintenance, analysis reports from Market Research Future suggest that the global market will register a robust CAGR of around 4 percent.

Sales will increase as consumers demand better care in this area. Here are some insights into educating your customers specifically about oil filters.

definition and function

An oil filter is made from a metal can along with a closure gasket, which allows it to be airtight and tight to the engine surface. The base plate of the gasket has several small holes across the space that is just inside the gasket. The central hole is looped through to the oil filter system on the engine block.

Inside the can is the filter material, mostly made of synthetic fiber. There are two main types of oil filters: the cartridge/element type and the spin-on type. They both do the same thing right, but in slightly different ways.

The purpose of the oil filter is to constantly clean the engine oil of small pieces of carbon and metal. Soot particles naturally detach from the moving engine elements as the driver uses the vehicle. Unfiltered, the vehicle’s engine oil would become ineffective incredibly quickly, causing catastrophic damage to the engine.

The particles wear out moving parts in the engine, especially bearings. Sooner or later the wear will be too great and the engine will stall. In this case, the owner is looking for either a new engine or a repair bill well into the thousands of dollars.

As the name suggests, an oil filter refers to the part responsible for keeping the engine oil clean. Because of the filters in the component, engine oil can pass through while it goes through a filtration process that allows it to be clean as soon as it exits the filter. The part filters out any external pollutants, contaminants or particles, guaranteeing that only clean oil flows through the engine.


The engine is perhaps the most important part of any vehicle. The reliability and movement of the vehicle depends on the health of its engine. It’s easy to see why engine oil is vital to maintaining a vehicle – it’s responsible for keeping the engine running efficiently.

It lubricates the engine’s internal moving components and reduces friction-related problems. It also provides protection for the engine from any kind of damage, corrosion, rust and any external pollutants. On the other hand, engine oil can also accumulate pollutants over time that can affect the protection of the engine. This can endanger the entire internal system of the vehicle.

As previously mentioned, engine oil is vital to the health of the engine. Over time, if left alone, engine oil can become inundated with small, hard particles that accumulate and wear out the engine. In addition, dirty oil can also damage oil pump components and damage engine bearing surfaces. Therefore, engine oil must remain clean. This is where the idea of ​​the oil filter comes in.

The right filter

Because oil filters perform an important job of keeping engine oil clean and protecting the engine from contaminants, choosing the right filter is paramount. Because most filters have identical parts and function in an identical manner, there are some minor variations in design and size that are important to be aware of.

It is the ideal choice to follow the instruction manual that comes with the vehicle to find out the specific characteristics of the model. An ill-fitting oil filter can rupture, leak or wear out other components – and give the vehicle owner a whole new headache. As a technician, you make a significant contribution to ensuring that the customer gets the right and best filter for their vehicle.

There are a significant number of components that go into making a quality oil filter. Original equipment manufacturers describe what their vehicles need. It is the engineer’s responsibility to ensure that the end customer receives the part made for their specific vehicle.

This ensures a trusting relationship.
