I have a 2011 Acura TSX Wagon and, up until now, I’ve changed my oil and filter every 7,500mi using Honda branded filter and Mobil 1. I’m considering changing to a Fram Ultra filter and replacing it every other oil change. I plan to extract the oil via the dipstick tube using a vacuum pump for the oil only service. This will eliminate the need to drive the car onto ramps, remove the underbody shield, filter and drain plug to only once every 15,000 miles. The filter is pretty small and I'll check to see how much oil is left in the pan after the first extraction so I have an idea of how much extra used oil I am leaving in the engine.
