I changed the oil and Blackstone said to retest after 4000 miles. I've hit that mark, so I bought a little squeeze syphon hose, but can't seem to get it far enough down my dipstick tube.
There are basically 3 ways to take a sample:
1. While draining the oil for an oil change. Wait until the oil is about 1/2 drained & get a sample from the stream.
2. Down the dipstick tube with tubing and a vac pump. Both Blackstone & JG Lube Services sell kits. Reuse the pump but only use the tubing once.
3. Most diesels have a pressure port somewhere and a special valve assembly can be installed to pull a sample. This method can also be used on an Allison transmission. I installed one of these on my Allison because I test to see if fluid needs to be changed. The port assembly cost less than $30 and was a 10 minute job to install.
Since you have that bulb pump, take it to Lowes or HD and see if they have tubing you can get in a longer length to fit on the suction end of the bulb.
I commend you for doing the testing.
