[May 3, 2024]

Over the last few oil changes I have had an increased amount of iron in my oil. In my oil filter there has certainly been an increase of ferrous metal - very fine, almost a dust - no large chunks of steel.

I decided to put all of my oil change results into a spreadsheet to understand the trends.

I broke down the Iron ppm measurement to ppm/hour and then charted it to see what the trends were. Certainly between May 2021 and August 22 there was a large increase of metal. However, between April 2023 and April 2024 there has been a 25% decrease. Just something to keep an eye on.
