This guide will come in handy for anyone who’s looking to accurately evaluate all of the lifetime oil filter options out there. When you’re done with this guide, you’ll be armed with the knowledge of what to look for and how to select a lifetime oil filter that will serve your Harley well. Below, you’ll find 6 factors to consider when looking for a lifetime oil filter.

The Problem With Online Reviews

A lot of customers base their purchasing decisions on online reviews. It’s understandable why people do this (even we do this sometimes). It’s only human nature to trust other people’s recommendations more than advertisements. However, online reviews aren’t always accurate. The internet is rampant with fake reviews. Even though some brands (like us) only post real reviews from genuine customers, a lot of brands post fake reviews in order to make themselves look better. If you see a questionable brand with loads of 5-star reviews, proceed with caution.

Facts about the products themselves should always be considered along with online reviews. You will have a better chance of finding a quality lifetime oil filter by thoroughly researching your options instead of just relying on reviews.

As long as you take into consideration the following factors, you’ll be bound to make a good choice when deciding on a lifetime oil filter.

1. Type of Magnets


Quality lifetime oil filters come with magnets that create a magnetic field within the filter. This is to capture all the tiny metal particles the oil has picked up while running through the engine. Neodymium magnets are among the strongest magnets in the world, they’re resistant to corrosion, and they last well over 100 years.

Simply having generic neodymium magnets inside the oil filter isn’t enough, though. Hardware store grade neodymium magnets lose effectiveness in temperatures over 180 degrees. Motor oil commonly operates at temperatures up to 220 degrees. So we use higher grade neodymium magnets that are certified to not begin losing magnetism until their operating temperature is over 250 degrees.

2. Fitment

Fitment is always important when it comes to oil filters. Your lifetime oil filter has to have the correct capacity for your engine. Avoid lifetime oil filters that are designed with universal specs. Instead, go with a lifetime oil filter that’s designed for your specific application.

3. Quality Metal

Metal mesh

Since your oil filter needs to handle high temperatures and oil pressures for a long time, the quality of the housing and the filter itself matters a lot. The housing has to be corrosion-resistant because it’ll be exposed to external conditions. The filter has to be able to handle extremely hot oil indefinitely without warping or corroding. And it needs to handle extreme oil pressures.

Aluminum and stainless steel are great materials to look for in a lifetime oil filter.

4. Quality O-Rings

O-rings are another component that should last a long time. It’s common for o-rings in oil filters to break down over time from constant exposure to heat and pressure. A good lifetime oil filter comes with durable o-rings. Viton (a synthetic rubber and fluoropolymer elastomer) is a great material to look for in o-rings because it can withstand heavy exposure to heat over a long period of time.

5. Quality Manufacturing

Our filter housings are CNC machined from 6061-T6 billet aluminum stock. They are designed and machined to the tightest possible tolerances. PurePower! is an ISO 13485:2016 Certified company.
