Oil testing and capturing sample.

[joecool911]

I've got 20k on my oil change since the Frantz bypass filter install with paper change every 1,500. Wanting to have a sample tested.

What's the procedure for obtaining a sample? I've seen recommendations in the past for testing facilities. But maybe for the discussion of taking a sample and sending it off for testing it would be best to combine them here.

There are so many ways , midstream sample (as i's changed)  Thru a pre -installed sampling valve , suction line into sample cup .

Hey, my bypass filter sends filtered oil back to the oil fill on the valve cover. Anything wrong with taking the sample from that discharge? That'd be simple to get a sample! Leave engine running and remove the fill plug and fill the sample container. I don't think it'd get much cleaner than that.

Clean the plug and the pan around the plug with a regular paper towel. Dont use any cleaners. Drop the plug then get three different samples of the draining oil into your sample bottle

My friend had to install a T where the oil line goes into the bypass filter head and capped it. When he takes a sample, he removes the cap, installs a valve, runs the engine and draws a sample. Then kills the engine, removes the valve and replaces the cap. Takes a few minutes and still has minimal weight on the line. And no mess. Just a thought.
