My wife and I have been going to Mobil 1 for years - ever since we moved to Willow Grove in 2005. We have always had a great experience. The staff is friendly, courteous and professional in every way, taking the time to explain in detail what services they are providing and why, and always doing an excellent job. They are very knowledgeable and thorough. Having had less than stellar results from other service centers, including dealership service, these guys are a great find... trustworthy, honest and reliable... AND inexpensive. And you get a free carwash... it's a great deal.
