With a company that started the game of filtering engine oil to the spin-on filters they have today, Purolator boss oil filters have become one of America’s top oil filter suppliers.

A good flow rate is essential for an oil filter because an engine needs oil pressure to run. The oil getting to the necessary parts on time is crucial. With the Purolator boss oil filter, it gets the job done. However, this filter uses synthetic media for the filter. Although synthetic media has been proven to be quite good at catching particles it may be better than paper media in some instances. This is why it’s important to pay attention to your oil filter change intervals according to the manufacturer’s recommendations.

The Purolator boss oil filter has a synthetic media with its smart fusion technology, taking filtering to another level. Synthetic media can catch particles from a range of 20-70 microns. We can only see particles 40 and above, so rest assured this filter cleans your oil well. As you can see in the image below the filters are usually folded for more surface area, which is how Purolator is designed. This contributes to a longer lifespan. The purolator boss oil filter protects your engine for up to 20,000 miles. Although this filter is very capable it is important to practice changing your oil and filters between 3,000 – 5,000 miles for synthetic oil filters.

Hello! My name is Javaughn Barrow, a young car enthusiast who writes all the articles for Karcandy.com. I’ve written over 50 articles about automobiles. With each article, I deepen my understanding and expertise in writing and the automotive world. Ever since childhood, I’ve always had a strong passion for cars. All types shapes and sizes were interesting to me. I’d spend most of my time after school researching cars and the more I found out about them the more exciting it was. In my teens, I created a fan page about corvettes posting content at least ten times a day! Yes, I was crazy about it. The page ended up garnering over 40k followers! After a while, I wanted more than a fan page. I wanted to express my passion differently. I wanted to create more helpful content, higher-quality content. My first car was a 2013 VW CC Sport. Learned very quickly car ownership wasn’t as expected. I spent a lot of time replacing control arms, cam position sensors, brake rotors, brake pads, etc. Walking away with more information than I knew before. As I was growing in my automotive journey I was learning about writing. Starting by writing a detailed outline about 300 words long then I would pay a professional to write a full 1000-word article and learn from them getting familiar with the process of writing. The moment I realized I could use my writing skills to express my passion for cars and help people simultaneously, I started Karcandy.com. I realized with my unique perspective coupled with my hard work discipline and work ethic I can create a space online to help bridge the gap between the complicated and simple in the automotive world. I’m motivated by the challenges and work it will take to create such a space. My work ethic is something I choose to refine and make better each day. I think it’s important to push myself and stay committed to my evolution as a human and this website is only one of the results of that.
