Aircraft Oil Sampling Procedure
- Fly the aircraft before sampling. At minimum, fly the pattern a couple of times. That should help eliminate any normal moisture or fuel build-up. Then let the engine cool down a bit before sampling so you don’t to get burned.
- If you’re using a pump, thread the tubing down the dipstick to draw the sample into the bottle. The tubing can be cleaned with kerosene.
- We need 3 oz to complete all our tests. But even if you only have 1 oz, we can still do at least some of our tests. If you have questions, call us at 260/744-2380.
- Complete the oil sample information slip.
- For the Unit ID, use your N-number to identify the aircraft.
- For Make-Up Oil, put down the number of quarts added between oil changes.
- Wrap the sample in the gray material and put both in the plastic bag. Put that in the black mailer. Put the mailer and the form into the white envelope and drop it into a mailbox.
Some post offices mistake oil samples for hazardous material. Oil is not hazardous material. Blackstone Laboratories’ oil sample kit meets all postal requirements. To see a letter you can give the post office to help reassure them, please click here.
