Question Regarding Oil Test

[Bikeman315]

I am scheduled to get my oil changed in two days and wanted to pull a sample to send off after I got it warmed up today. The 1/4" tubing that comes with the Blackstone pump seems to hit an obstruction about 4 or 5 inches down the dipstick tube, so I was unable to draw a sample. Are you having oil tested as you drain from the drain plug, or do you have any hints as to the size of tubing I might be able to get down the dipstick tube on a 2019 Coyote?

Thanks for any suggestions.

I had the mechanic pull the sample when he did the oil change.

Just email or call Blackstone and they will send you a smaller diameter tube. They are very responsive and I had the smaller tube in just a few days. Now it works perfectly, no obstruction. Hard to find that smaller tube at local hardware stores.

Thanks for the responses. I did send a message to Blackstone, but I'm getting my oil changed on Tuesday, and wanted to pull a sample before then. Is what they sent you polyethylene? I went three places and everyone only had 1/4" and 3/8" OD polyethylene in stock.

However, at my local Menard's (mostly northern Midwest, I think) I found "Sioux Chief tomahawk Micro fuel line" right next to its limited selection of polyethylene tubing. This stuff is orange colored and is, apparently, for small-engine fuel lines, so it should be petroleum safe. It is 3/16" OD X 3/32" ID and came in a 5 ft. length. It is more flexible than polyethylene, but the dipstick tube acts as a guide, and it feeds down easily. I cut a 3 ft. length and it went right in past whatever the obstruction was. The Blackstone pump sealed perfectly around it, even though it is not as rigid as polyethylene. My oil was fully warmed up, so it pulled easily through the smaller diameter tubing. I highly recommend this stuff, if anyone else was having the issue that I was.

Good choice, what you found is basically the same OD as the one from Blackstone. As long as you are able to pump oil into the bottle, you are good to go. The Blackstone pump is very well made and worth every penny.
