I'm not ready to drain my oil but I want to get an oil sample. They say take the sample after you drain 1/2 the oil out. I have a Fumoto quick drain plug so can I just get the truck to operating temp & right after I turn it off get a sample before ALL the junk settles into the pan? TIA

 

Yes you can or you can get the sample pump from Blackstone that will allow you to take a sample through your dipstick. Yust keep in mind that the oil is probibally going to be HOT.

 

I just have the stock drain plug and all I do is warm the oil then drop the plug wait a few secs and catch the sample, its hot so I wear gloves

 

My AMSOIL and blackstone pumps never worked for the dipstick trick. LOL But I take mine after the truck is up to running temp when I pull the drain plug. I let it drain a few quarts and then stick just the edge of the collection bottle into the stream. THat way it fills slowly and does not splatter or burn my hands..

 

I won't get a drop of oil on my hands. I was just wondering if this is a good way of doing it.

 

This has worked for me. I have been trying to send a sample after 4k miles on the oil to keep the reports consistant. This is a post I did a while back.

I got the pump from Blackstone Labs. The pump comes with a 1/4" plastic tube. The 1/4" tubing is too large to fit down the oil dipstick tube. Right at the end of the tube is some sort of rib that stops a larger tube from going any farther. I bought some fittings & smaller tubing to get a sample thru the oil dipstick. With the new 3/16" tube, it went in smooth. I used the components from McMaster-Carr. Here are the items
(1) brass compression 1/4" od tubing 1/4" NPT female #50915K215 $1.87
(2) brass compression 3/16" od tubing 1/4" NPT male #50915K313 $1.87
(3) 3/16"od 1/8" id tubing with Teflon PTFE semi-clear $9.40 for 10 feet #5239K11.
Cut the 3/16" tubing to 60" If I remember right the dipstick was 46.5" long. I wrapped electrical tape around the 3/16 tube to mark insertion length and create a stop plug. Tube didn't crush down, it worked great. The tube was kind of pricey but wanted something stiff that coud take some heat. FYI

 

I do appreciate yall's advise but I bought the Fumoto drain plug for this exact reason. I don't need to pump it out to get a sample unless the Fumoto is not an effective way of getting a true reading. Do any of yall do it the way I'm describing & does it get you a 'proper' sample? TIA

 

I take my samples from the fumotovalve. Always turned out fine. But I have only done it at oil change time, which for me is at 5k intervals. I usually drain some off (maybe a gallon), stop the flow, get my blackstone sample bottle, then fill up the sample bottle with a slow trickle from the fv, then put on the lid, and reopen the fv for the rest of the oil drain. Hope that helps.

But I have never tried to get a sample in between changes. I guess it would work fine though.
