Antiseize got nothing to do with BMW drivers, it is just good practice when dealing with alu on alu thread fasteners or plain stainless fasteners for preventing seizures. Clear oil or grease will not work longtime on hot parts as it will smoke off and then same risk of dry seizures will set in. I was just curious about your statement of regular, annual lubrication in BMW business for ex pipe nuts. I´d believe once well-brushed with some antiseize would last decades, be it copper antiseize, MoS2 my preferred paste, or other antiseize, some ceramic types, no matter. Dow Corning Molykote once was quite familiar with MoS2 pastes, seems they switched to graphite instead, allright for threads as well I think. But in some BMW gearboxes I add MoS2 finest powder for extra protection of gears, would not want graphite in there.
Lubricating spark plugs is an intersting discussion, minimum copper grease on spark plugs is a must in aero engines ! But in more common vehicles Helicoil has earned their billions from owners who follow that religion of torquing the plugs in dry. Certainly the argument that with antiseize on threads torque numbers will not be suitable when ordinary oil was used in screw torque tests. I do have a torque wrench but it is rarely used on our fleet, you can never be so wrong by hand feel than by getting a torque wrench setting wrong. I say a lot more threads were fu***d up by using a torque wrench than by brute hand force .
