Just a simple visual. The lower the numbers, the cleaner the oil. The Oahu Clean Oil Filter does just that: it keeps your oil clean. Literally as clean or cleaner than new oil. It's that good. And clean oil doesn't need changing. Oil analysis is where a sample of oil is taken and tested. The results are sent to you.

In the images below, we can see typical oil analysis results done on new oil from the barrel, and oil from a Reefer engine with the EXTREME filter. Ultra-fine filtration kept the engine oil 2 steps of the ISO cleanliness code cleaner than new oil. Each step is a 2X increment, so that means the engine oil is technically 4 times cleaner than the new oil put in it. EXTREME is that good. And that's GREAT for your engine.

Once you get an analysis, you can use this pamphlet to explore the cause/solution for any warnings. Or, call !
***If you use a Gearhead analysis kit from the online store, fill out the information form, and then simply fill the provided bottle half way with your oil sample, seal it in the prepaid envelope, and drop it in the mail box. Results will be emailed in about a week.***

Oil color doesn't always mean oil is clean or dirty. But clear oil on a diesel usually means the oil is clean! The truck on the left has a delete and the EXTREME oil filter. The oil will likely be more clear. Lynn of Gearhead oil analysis explains another way you can tell if diesel oil is in better shape. But never depend on the clues alone, be sure to get your oil analyzed regularly. A blind oil change means you don't know what the oil analysis could have told you. The oil may have been still good if you have the EXTREME oil filter, or it may look good but be full of fuel and be causing damage to the engine. The only way to know for sure is to do the oil analysis. If the oil is good, keep on going! If the oil shows a warning, fix the engine problem, change the oil, and off you go again. This is smart maintenance! EXTREME bypass filters combined with oil analysis can save you thousands in wasteful oil changes and catch engine problems before you have to buy a new engine. It simply is smarter than just blind, expensive, wasteful oil changes.
