Warnings & tips

  • Your sample bottle uses a vacuum to pull oil from your engine. Do NOT move sample bottle valve until one end of the sample tube is connected to the bottle and the other is submerged in oil. Otherwise the bottle will lose its suction and you won’t be able to draw a full sample If this does happen, use Syringe instructions to complete your sample.
  • Engine must be turned OFF before you draw your oil sample. You don’t want the sample tube to get pulled into the rotating components of your engine as this will cause significant damage.
  • Wear protective gloves as engine oil is VERY HOT at operating temperature.
  • Make sure the sample tube is completely submerged in oil. Otherwise you will lose suction and won’t be able to get a complete sample.
    If this does happen, use Syringe instructions to complete your sample.
  • Clean any spilled oil immediately.
