Has modern technology surrounding the oil pan bolts gone suddenly backwards? ... Why didn't I need a washer for 50 years and now I do?
Because they hadn't yet thought of that trivial gimmick to increase parts-department sales? Or because careless people mangle plugs and washers, causing leaks? My OE plug washer, which Toyota claims must be replaced every time, actually works fine for multiple uses (up to 7 oil changes, so far) with no leaks. I don't abuse it.
