Oil Filter Buying Guide

There are many things to consider when shopping for an oil filter. You need to make sure you are getting a filter that is going to work well with your car’s system and prevent damage to your engine. The best oil filter will actually minimize the need to change your oil as frequently as you would with a cheap filter.

Oil filters come as a spin on canister or cartridge type and it is important that you get the correct filter for your engine. Below we have produced a detailed buying guide to help you make an informed decision regarding an oil filter for your car.

Oil Filter For Synthetic Oil

Compatibility With Your Car

The first thing you need to look at when shopping for an oil filter is whether or not it is compatible with your car’s system. The size of the oil filter in each car is different, so you will need to make sure the replacement filter you purchase actually fits into the correct placement in your engine.

If you are purchasing your filter on Amazon, you can enter in your car’s make, model, and year to find out if the filter is compatible. You can also search online to find this information, or you can ask your mechanic.

Cartridge vs Spin On

The two main types of oil filters are cartridge and spin on where both have their benefits. The cartridge filter uses a cellulose filter media along with other materials such as plastic. They have been used in vehicles for over 50 years but from the 1990’s, many manufactures moved toward the spin-on type of filter.

This type of filter uses a steel outer canister and provide more convenience when performing the replacement. However, according to EcoGard, manufacturers are starting to go back to the cartridge type due to government regulations and environmental factors.

Replacing the Filter

It is recommended that you change your oil filter every time you change your motor oil. Therefore, if you plan on doing a large amount of driving, the ease of replacing the filter needs to be easy. If you have the correct wrench, replacing the filter is fairly straightforward.

Simply remove the filter with the wrench and then clean up the area where it was located as some oil will spill. One thing that is important is that you change the gaskets and these will be included with the oil filters recommended. As you can see below, use a small ply tool to drag the gasket down in place.

Oil Filter Gasket

Depending upon whether you have a metal canister or cartridge oil filter, the steps you take may differ. Before reinstalling the oil filter, we highly recommend lubricating it with some oil on the seals and then put it back in place.

Once installed, you will want to start the engine and then check for any leaks. You may also want to recheck the oil level and top it up if required.

Exterior Durability

The outer casing of the filter is what protects it from damage while your car is running. Rocks and other debris can get into the engine, and they could puncture the filter and damage it. Therefore, it’s helpful to purchase a filter that has a durable exterior that is resistant to impact, pressure, and punctures. A durable exterior is safer for your engine and will prevent leaks.

Media Material and Size

The media is the part of the filter that catches the dirt and debris as it runs through. Generally, the more media that is included in the filter, the more likely it will be to catch all of the necessary debris. Therefore, you will generally want to look for a filter that has a higher density of media.

You should also look into what the media is made from and how it is constructed. A finer filter design is generally best, because it keeps out stubborn smaller particles of dirt and debris.

Filtration Efficiency

The filtration efficiency level is another important factor to consider when shopping for an oil filter. Your filter should be able to process at least 99 percent of dirt and debris that comes through it, so that your car runs on the cleanest oil.

The more efficient your filter is, the smoother your car will run, and the less often you will need to replace the filter.

Spin On Oil Filter

Silicone Anti-Drainback Valve

Dry starts are very dangerous for your car, and they can happen when oil accidentally drains back into the filter instead of out into the proper channels. A silicone anti-drainback valve is a must on any filter that you purchase. These valves ensure that the oil goes where it is supposed to, preventing dry starts and other damage. These valves are also helpful for preventing leaks.

Filter Capacity

The filter capacity is how much dirt and debris the filter can hold. It’s important to look for a filter with a large capacity, because it will last longer and require less maintenance. Many premium filters are specifically designed to maximize their space to hold more filtered material for your convenience.

Replacing Car Oil Filter

Compatible with All Oil Types

Today there are multiple types of oil that car mechanics use. In addition to traditional oil, there are also many types of synthetic oils. A good filter will be compatible with any type of oil. This not only protects your engine more effectively, but it also makes your car easier to service. If your filter is only compatible with one type of oil, it will make maintaining your engine much more inconvenient.

There are so many choices out there when it comes to oil filter replacements for your car. It’s helpful to invest in a high quality one, because it will mean fewer oil changes and less hassle. Use this guide to help you choose the best oil filter for your needs. If you still aren’t sure which filters are compatible with your car, consult your mechanic or another car expert for more personal guidance.

Conclusion

Spending the small amount extra for a quality filter than has been developed by a reputable brand is highly recommended. The purpose of the filter is to keep the motor oil clean and free of contaminates.
