DIY oil testing using a fairly simple technique, Oil Spy http://www.oil-spy.com/

If you remember doing Chromatography in your high school high class using blotting paper you will latch on to how it works.


As an experiment I tried putting a drip of oil from my tintop on some kitchen roll but as the oil was changed just 1,000 miles ago, and the car runs on lpg so it didn't really show up anything. However a spot of old ATF drained from the power steering showed up metallic particles.

looks intesting, in comercial world we use to have diesel oil tested on large 1.5Mw static generators with 1000litres oil and it was amazing what they could tell, we had one report saying aluminium in the oil and the type as piston ring land adjoining material, when we stripped it down there was one pisting failing

Good find. A few coffee filter papers will do nicely.. I guess the real ones on that site use a proper analytical paper (no idea if this exists) to get repeatable results.

Quite like the real thing mind as you could keep them to record what is happening over many years... Not expensive anyhow (50p each)...
