Run the engine before you take the sample to get the oil at operating temperature (driving about 15 minutes should do it). Getting the oil up to operating temperature should help cook out any normal moisture or fuel build-up.
Use a vacuum pump or Lubemonitrix syringe to take the sample through the dipstick opening. The Lubemonitrix test kit provides a syringe and tubing to help you take your oil sample. These items can be ordered from this website from the buy online section.
