which doesn't match the benefits of UOA:

my wife's 325i was sampled at 20K and 15K on the last 2 oil changes - in both cases the dealer told us to wait for the sensor to tell us to change the Oil. (which was showing up to 9 months left on the oil)

my UOA results showed elevated wear metals like alluminum and copper, and more importantly the viscosity was elevated indicating that the oil had begun to oxidize.

if making this kind of analysis was that easy there would be an app for that!

I like it.

I was a backer too, still waiting on mine in the mail, I will report back on how it works when I get it...

I just saw this online. I thought to myself "I wonder what the guys over al bobistheoilguy will think of this". Looks like I was too late.

any reviews?

Dangerous postings cost engines, this device has been around the snake oil circuit under different names for years. All it can do is measure acidity and conductivity in a fairly inaccurate manner. That can only warn you that you have a seriously high level of anti freeze in your oil or the oil is so full of wear metals its electrical resistance has changed.
Stick to the old blotting paper tests as they are cheaper and can even spot fuel contamination which this device can't.
If you are worried about your old oil try Blackstones or just change it more often.

VERY TRUE! Although the oil service computer in a BMW uses a much more expensive test unit and it does give a rough guide when to change the oil based on wear metal conductivity and dielectric changes, but it is not triggered until they are fairly high. Most of the change oil warning systems just watch engine RPM and count the stop starts along with average temperature.
Anti freeze will set if off fairly quickly, but the thing people forget about the dealers, is that they are not interested in the real long term life expectancy of your engine, they just don't want it to fail whilst the car is under warrenty. The fact it blows up the year after is not their problem, which is why they are pushing so hard for extended oil change intervals without doing individual detailed UOA or consulting with a real oil analysis expert.

I stumbled on to this thread while searching for something else and coincidentally saw this device listed in the Parker/Racor Bypass Filtration Catalog:

Here on pg. 11

I'm going to inquire with Parker/Racor on their Bypass systems and ask them about it ect......
