Anyone seen, used or have an opinion on this oil check device?

lubricheck The digital 'blood tester' for your car

Someone on the 6.5 forum posted a link to it. I've never run across it before.

My buddy has one of those and I've used it, it seems to work well.

Nifty gadget, and not expensive, $40.00. Maybe gets rid of the scheduled every 6 month oil change ... ?

Having just spent $90 on 2 gallons of oil, a filter and 5 quarts of transmission fluid for my wife's Land Cruiser I'm in the mood to buy one.

Wowza ... that's a bunch.

Overall, the little plastic device impressed us, and it appears to provide consumers the information they need to extend oil change intervals. Of course Lubricheck isn't as accurate as spectroscopy, flash point, viscosity and chemical-based oil testing we will still mail samples to Blackstone Labs for that.
What else should be noted is the lab result gives you a hint of what is wearing down and you don't need to do it every few miles. You do it once a year at best and they recommend what the OCI is. Also you can do different tests in case you like say a new brand of oil and see if it works.

Looks good but ....

What test is it actually running? Is it looking only for particulates?

Those of us , mainly dieselheads that like oil with an extra dose of zinc and/or AMSOIL fans may find erroneous readings as their website states.

For forty dollars it has to have limits. Find out what they are. I do not suspect a simple device like this can measure soot levels that are all important in the old indirect injection diesels though.

Look up the oil blotter test. It is an old test but does give you some important information. Also litmus strips may tell you when the oil is getting acid easily enough. Especially for cars where the vast majority of driving is on very short trips.

The litmus strips may also be good testing for your coolant as well using a meter at the same time to evaluate it.

How does the Lubricheck work?

The Lubricheck uses a patent pending technology that measures the capacitive and resistive properties of oil. Oil degrades due to mechanical friction, high temperature, high pressure, moisture, oxidation, and absorption of contaminants. These changes cause a change in capacitive and resistive properties. The Lubricheck compares the sample being tested with stored values of fresh oil and displays the results by lighting 1 of 10 LEDs.

e

So fundamentally you can do the same test with a meter. Just need a constant fixed separator of the probes. A meter that also has a capacitance function.

Possibly the simple blotter test is even better. Using cheap litmus paper strips with it as well may be still further advanced over this tester.

Neither tests will give us soot levels I believe and they are important on these old diesels.

This generic comparison is its weakness. I dont know how new dino compares with new fully syn.
its unlikely that its a test you would use for a very expensive motor.
Would be interesting to see data of how resistance & capacitance varies with soot level, other contaminants & oil breakdown.

Find the old engine oil blotter test. I always thought it was pretty good. Basically you read the spread of the drop of oil on the blotter and there is a wide range of things to observe.

I suspect it is useful on diesel engine base oils as well. It certainly is on the gas engines base oils.

I think it was back on 98.
