9 Best Oil Filters for Synthetic Oil

(Updated on July 28, 2022)

The purpose of an oil filter should be self-explanatory. When oil circulates through your internal combustion engine, it needs to be as clean as possible. There are all sorts of harmful substances and dirt particles which can exist in oil if it is not filtered and cleaned properly.

This is especially true if the oil were to ever become contaminated by some outside debris. If contaminated oil were to circulate in your engine, it would weaken the engine’s performance or possibly cause it to malfunction altogether. There is even a chance of overheating too.

An oil filter basically consists of a retainer, steel tube, pleats, tapping plate, and a filter medium. However, there are different types of oil filters which are made specifically for certain types of oils.

Since many car owners use fully synthetic oils these days, this means a high-quality filter is needed. After all, the benefit of synthetic oil is that it’s specially formulated to do a better lubricating job on the engine’s components under many conditions.

If the oil were contaminated, then its special properties would not be apparent. As a result, your engine will suffer for it.

Top 9 Synthetic Oil Filters

1) Purolator Boss Oil Filter

Purolator Boss oil filter reviewPurolator is an oil filter brand which has been used in vehicles for more than 9 decades. It is the top brand as far as oil filters go. Their Purolator Boss oil filter works wonderfully with synthetic engine oil.

It will give you up to 15,000 miles of oil filtering before you need to replace it with a new filter. That’s not bad, considering that most experts will recommend you change your oil filter after every 5,000 miles.

The Purolator Boss oil filter contains premium components and materials, such as a metal bypass valve, metal center tube, end caps, and silicone anti-drain back valve. It is designed to withstand a lot of heavy driving and demands on the engine.

The filter is described as having a “high density synthetic blend media,” which gives it a 99% efficiency rate.



The components of the Purolator Boss oil filter are made from silicone and metal. These materials give the oil filter the most durability possible. In fact, you can get as much as 15,000 miles on this oil filter before it needs replacement.

Comparable oil filters on the market will barely last between 5,000 to 10,000 miles. This means you’re getting good value for your money here. That said, it’s recommended that you replace your oil filter at the same time as your engine oil.

Trusted Brand

Purolator is a trusted and reputable oil filter brand. You can rest assured that you’re getting a top-quality product whenever you purchase a filter from Purolator. Their Boss version of the filter is one of the very best they sell. It has great customer reviews and continues to be a top seller.

99% Efficiency

The Purolator Boss has more than a 99% efficiency rate in this filtering job it does. In other words, at least 99% of all the contaminants and debris will be filtered out of your engine oil if you’re using this oil filter. Other comparable oil filters only give you around 96.5% efficiency. The Boss helps keep your engine running clean for as long as possible.



If you were using the Purolator Classic oil filter, you could get it for an affordable price. But the Purolator Boss is a premium version of this oil filter, which means it costs more money.

Even though the Boss version is more durable, you might not care if you’re someone on a tight budget who wants to save money. In that case, the Boss might be something you’d rather not spend the money on. But for something that you probably only replace once or twice a year, a few dollars more is worth it.

Not Suitable for High Performance Vehicles

As previously stated, this oil filter has a high-density media. This slows down the oil flow rate of the engine oil. If you’re driving a high-performance vehicle, such as a race car, you need to have a fast oil flow rate. Therefore, it’s not recommended to use the Purolator Boss oil filter with it.

2) FRAM Ultra Synthetic Oil Filter

8 thoughts on “9 Best Oil Filters for Synthetic Oil”

  1. Why pros/cons on only the most expensive filter? Especially considering that the Boss has a pro of the most durability possible at 15K miles but the Fram to has protection for 20K.

  2. I have used castrol edge 5w-30 synthetic oil in My 1999 Lexus 3.0 L non-turbo v-6 engine. I chance the oil every 2500 miles and when I do it (oil) looks like the day I first filled it. amber) I have 247,000 miles on it and still running silky-smooth and strong. I also use a Purolator BOSS filter w/great results.

    • Sounds like your Lexus is in good shape, especially for the mileage. You could probably even stretch that oil change interval out a little more. The reason the oil comes out looking new is because 2500 miles is hardly anything for a synthetic oil. Many of those oils can last from 5-10k miles depending on the vehicle and the oil.

      You may be interested in a used oil analysis (UOA) from a company like Blackstone Labs to see how your engine is holding up after all these years, and how long you can safely go without changing the oil.

    • They have great ratings, too. It’s just important to use a Quality Filter and Quality Oil. I use the WIX Premium XP, but K&N has great ratings, too.

  3. I have been using the WIX XP for many years and I leave my synthetic oil in the car for up to 10,000 miles. I had it in my “01 Suburban for an entire year, but have not been driving it much since I didn’t travel through Mexico that year. I figure my last change was at 6,000 miles of usage and the oil still looked clean. With over 300,000 miles on this car and this engine, it does not use a drop of oil between oil changes unless I let the car sit and the gaskets start to shrink – keep in mind in a hot climate you have to use the car to keep the gaskets from drying out. I use Castrol Synthetic. Once a mechanic put in regular oil and it sounded like a bucket of bolts and nuts until I drained it and put the synthetic back in it – it got quiet immediately thereafter. I highly recommend synthetic oil and a quality oil filter that can hold up for 10,000 miles.
