A. Follow the oil analysis provider’s oil sampling guidelines. The best way to obtain an oil sample is to use an oil valve directly attached to the engine port. This sampling method reduces human error as well as the tendency for contamination and promotes oil sample consistency.

If using the more common methods of sampling, via the drain plug or with a suction gun, it is very important to adhere to housekeeping rules, otherwise oil sample data can be negatively impacted.
