One of the benefits of oil analysis is that you can usually get more use out of your oil and go longer in between oil changes. But because all engines wear differently, the only way to tell for sure whether you can do so is to analyze the oil. If you don't want to change the oil in order to get a sample, then you need a hand-operated vacuum pump, which draws a sample up through the dipstick.
Please note: The pump does not automatically come with a sampling kit,
but we'll be happy to send you one if you make a note when you place your order.
