Agreed but there is no doubt the quality and functionality of todays lubricants is light years ahead of that used in the day. I have run restored BMC engines in cars for 50000 miles with no engine work . My mechanic grandfather spoke of the same engine in the day regularly needing a valve job at 10000 miles and the bottom end at 30000 miles Something has changed and in this case it isn't the engine -Karl
