Diesel Engines and Lifetime Oil Filters – What You Need To Know

Having a diesel engine means maintenance can get pretty expensive. One of the best and easiest ways to save money on diesel engine maintenance is to get a lifetime oil filter.

What is a Lifetime Oil Filter?


A lifetime oil filter is basically a permanent oil filter made of high quality materials. At Pure Power!, we make the best lifetime oil filters on the market. Our lifetime oil filters have:

  • Double woven 304 stainless steel filter media that traps a lot more dirt and debris than the filter material found in disposable oil filters
  • Powerful neodymium magnets to trap metal particles in the oil – even the particles that are too small for disposable oil filters to catch
  • Viton o-rings that can withstand high heat, oxidation, and years of use
  • Stainless steel emergency relief valve internals
  • Durable and corrosion-resistant 6061-T6 aluminum filter and emergency relief valve housing

Pure Power! lifetime oil filters are made to serve your engine over the course of its life.

How Does a Lifetime Oil Filter Save You Money?

Diesel engine

Depending on your diesel engine, a disposable oil filter can cost you up to $75. A diesel engine can easily last up to 300K miles. If you change your oil every 5K miles, that’s 60 disposable oil filters. That means you could spend up to $4,500 on oil filters alone over the lifetime of your diesel engine. Even the cheapest diesel oil filters, which are about $7, will run you up about $420 over the lifetime of your diesel engine.

And that doesn’t count the time and fuel you use just going to get the oil filter. Even if you only spend 15 minutes getting each filters, that adds up to over 15 hours of your time over 60 oil changes.

That also does not include labor. Even though it takes about 15 minutes to change an oil filter on a diesel engine, shops will charge you a minimum of an hour’s worth of labor to get the job done. Since shops charge about $100 per hour, you’d be paying about $6K in labor alone over the life of the engine. It’s just best to get a lifetime oil filter and then clean it on your own in regular intervals.

A Pure Power! lifetime oil filter costs between $200 and $700, which is a fraction of the amount you’d pay for disposable oil filters over the life of your engine.

Do Lifetime Oil Filters Really Last a Lifetime?

Yes, lifetime oil filters can last the life of the engine (and more) if you choose the right brand. You want a lifetime oil filter that’s designed well, built with great workmanship, and made with high quality materials. Pure Power! lifetime oil filters meet all of the criteria for a durable and reliable lifetime oil filter for diesel engines. Even better, all Pure Power! lifetime oil filters have a limited lifetime warranty. In the rare occurrence that a component within your Pure Power! filter fails during normal use, you can have it replaced for free.

Cleaning Your Lifetime Oil Filter

Clean oil is crucial for long term engine health. It not only keeps the engine components in good shape, but it also improves the engine’s overall performance and fuel economy. Lifetime oil filters need to be cleaned about 3 to 4 times a year, depending on how much you drive your diesel vehicle. The cleaning process is simple:

  • Remove and disassemble the filter
  • Soak the components inside & out in PurePower! ECO Sudz
  • Blow the filter & bypass relief valve dry from the inside out
  • Reassemble the oil filter

We also offer the new PurePower! ECO Shower, which streamlines the entire cleaning process in one easy to use package!
