I searched the forums but didn't find a thread with this subject. What is the differences beteween these products? They seem like they are setup to do the same job. You can get the LC20 for 33.00 a gallon. My father and I currently use the Auto RX on a maintance dose (2001 M Roadster 2006 Mustang GT). I have learned a lot about oil, additives, and the true about oils. Sorry if this a repost, just wanted to get some advice. Thanks
