The suction pump is used by most garages now as it saves removing all the panels under the car and replacing the drain plug gasket. Many car makers expect a whole new plug to be fitted.
There is one customer that takes passengers to London airports in a Mercedes luxury mini bus. He would be driving around 1200 miles a week minimum so looks in often for new oil and filter. He always brings his own preferred oil and filter and watches during the oil change. His last vehicle engine had done well over 300,000 miles but it had a lot of other mechanical failures of steering and suspension as it was about 2.5 tons in weight. Eventually, that car began to look tatty for a luxury car hire so changed for the Mercedes bus. Vehicles used for many passengers and luggage are hard to keep in good nick. Good customer who knows how to keep his vehicle running. He is aged quite a bit over 60.
