My son's SF uses a Mahle oil filter. Over Christmas I did an oil change with a Mityvac 7201 fluid extractor, worked like a charm and got just under 6 quarts out. I may never crawl underneath again. I did not change the oil filter b/c of time constraints. I typically run 5k mile oil changes using a top tier synthetic 5w-20. My question is would there be any harm running the Mahle oil filter for 10k miles (2X oil changes). Would be particularly interested to hear from the master technicians and others in this forum that have pulled oil cartridges out of the 3.5 engines at all mileage intervals. TIA.
