Your Complete Guide to Buying an Oil Filter for a Hyundai

Changing an oil filter often falls to the bottom of the to-do list, but those who want to keep their Hyundai running smoothly have to buckle down and find a good oil filter for their vehicle. Even through oil filters are low cost, disposable items, they are an essential part of the automobile. While driving, the oil flows through the moving parts of the engine to keep everything well lubricated and minimise friction. As time passes, the oil gets dirty and it is the filter's job to rid the oil of as much contaminants as possible. If the oil is dirty, the engine has to work harder. Not only does this require more petrol, but it wears the engine down faster. Failure to replace the filter could result in the motor seizing up. If this happens, a new engine is needed.

It is true that shopping for an oil filter can be confusing, especially for those who are not familiar with the mechanics of an automobile. Pretty much all oil filters look the same. However, each engine requires a specific size of filter, otherwise it is not going to fit. In addition to this, there are many brands to choose from as well as different qualities to select. The cheaply-made oil filters can work, but they do not last long and they certainly do not keep the oil as clean. They also run a higher chance of leaking. If the vehicle is dripping a dark substance in the garage, it is possible that the filter is no good.

The many kinds of oil filters for Hyundais are available to meet the different needs of individuals. The important steps to finding the right one include selecting the proper size, choosing the quality of filter, and deciding on the brand to purchase.

How Oil Filters Work

The very first combustion engines did not use filters and had to have their oil changed frequently. Although the filter systems are still not perfect, they allow vehicle owners to go for a longer time period without changing their oil.

The oil in the engine passes into the filter through small holes at the base. It is then pushed through the filter and back into the engine through another hole at the end. The trouble with filters is that they can get clogged or they may prevent the oil from passing through at times when the oil has become too thick. To prevent this problem, most engines have a system that directs the oil around the filter when the pressure builds up. This prevents the engine from seizing, but also permits dirty oil to circulate through the motor. There are certain oil filter features that can help reduce this problem, but even the best filters must be checked regularly in order to protect the engine.

The Important Parts of an Oil Filter

To best understand how an oil filter works and which features are important, one must first have a basic knowledge about each of the main parts. Different brands construct parts differently which determines how reliable the filter is.

Filter Element

The pore size and the material used determine how effective the filter is in capturing the particles in the oil. If the pores in the filter are small, they can effectively capture the contaminants, but they clog up easily and slow down the flow of the oil. Larger pores do not inhibit the flow or clog as easily. However, they also do not prevent as many particles from getting into the engine. The majority of the filters block particles that are .005 cm in size. However, look at the manufacturer's website to see what they have to say about their filter elements and what situations they are best used in. For example, those who live in colder climates should opt for filters that have larger pores because oil becomes thicker as it gets colder.

End Caps and Core

The filter is held within the core and sealed in by the end caps. Originally, the core and end caps were surrounded by steel. These days, however, the manufacturers are beginning to use plastic and paper end caps. They claim that by laminating the end caps, they last as long as they need to at a lower cost. However, studies have shown that the paper end caps are disintegrating and then getting caught in the oil system.

Pressure Relief Valve

The pressure relief valve, also called the bypass valve, has a spring on it that pushes in when the pressure builds up. If the spring is pushed all the way in, the opening to the filter is closed off. The oil flow is then directed around the filter and back into the engine. This is an important feature to have in the event that the filter clogs or the oil is too thick to pass through the filter fast enough. However, if this goes on for too long, the engine could be damaged.

Anti-Drainback Valve

The anti-drainback valves keep all of the grime extracted from the oil within the filter. If this piece is not included, the filtered product can flow back into the oil line when the vehicle is shut off. The silicone valves tend to last the longest.

Oil Filter Brands Comparison

Without a doubt, there are far too many options to choose from when shopping for an oil filter. After looking up the model number needed for the Hyundai, there are multiple brands to choose from in a wide range of prices. The following brands are listed in order of best choice and were selected as some of the best due to their value, valves, and construction.

Oil Filter Brand and Model


Purolator PureONE Oil Filter

The PureOne filter gets the top placement because its quality construction and affordable price. However, high performance vehicles should avoid this one because the filter is made out of denser material that could restrict oil flow in high pressure situations

Mobil 1 Extended Performance Oil Filter

While Mobil 1's filter costs a little more than others, it is priced high for a reason. Their filters are quality made, capture a good amount of debris, and they do not restrict oil flow

Purolator Classic Oil Filter

The Classic Purolator is a better-than-average filter with a paper element that does a decent job at blocking out particles and keeping the oil flowing at the same time

WIX Spin-On Oil Filter

WIX filters are priced the same as the low-end filters, but they offer a better quality

In general, vehicles should have their oil replaced every 3,000 miles. When the oil change is done, the filter also needs to be replaced. If a good filter along with quality oil is used every time, the Hyundai lasts alot longer and requires less maintenance throughout the years.

Shop For Hyundai Oil Filters on eBay

Most general automotive shops have several oil filters to choose from. However, they tend to only carry the most popular brands, which are not necessarily the best brands to select. Rather than trying to read and understand the product description on each box, shop online at eBay where you can look through all of the brands and choose the ones that are most trusted.

There are several ways that you can search for an oil filter on eBay. The first option is to search by the vehicle model such as "Hyundai Accent oil filter". This brings up specific filters designed for your automobile. The other way is to be more general and search for "oil filter" instead. Sometimes the car's make and model is not listed in the product title, so the more general searches show you more options to browse through. If there is a particular brand you want, go ahead and search for it by including it in the title. For example, you can look for a "WIX oil filter".

As you shop, check to see what the postage costs are because that increases the overall cost of the filter. It is also important to make sure that the seller accepts returns for any defective products.


As most people already know, the oil is what keeps an internal combustion engine running. Without it, the engine would literally melt itself together due to the heat from the friction. In order to keep any automobile running for as long as possible, the oil needs to be replaced often and so does the oil filter. The quality of both products has a huge impact on the vehicle's performance and its lifespan. Since oil filters cost very little in comparison to the price of a new engine, there is no reason not to spend a few extra pounds to get a quality product with less chance of destroying the motor. Buyers can research the materials and methods that manufactures use to produce their filters, or they can just shop from trusted brands that they already know make quality filters.
