Our oil change place (a reputable transmission shop) told us that during an oil change on our 2012 Honda CR-V the threads in the aluminum oil pan had stripped due to electrolysis with the steel drain plug, and that our oil pan would need to be replaced for $1,100. However, everything I have checked online and with another mechanic indicates this is nonsense, that the only way this can occur is because of overtightening. Can electrolysis between the plug and pan actually destroy the oil pan threads?
