Sorry for another thread...Im new and Im unsure of how to delete other threads...After reading on here that group III synthetics dont cling to metal, but its the add packs that help it to cling, its got me a little concerned...I start my car many many times per day, and from what Im drawing about group III oils is that they just all leak down into the pan leaving your engine parts dry for the next start...This cant be good! especially with all the many starts I do per day. How well does the Castrol Edge w/ Titanium cling to parts? will there be sufficient oil film for morning starts and the multiple starts per day I put it through? Its 5W20 by the way, I dont want to move up to 5W30 and I dont want to put Lucas or anything in the oil. Is this a legitimate concern like Ive been told, or is it just bunk?
