this is NOT a cost saving stunt, nor is it about a "new super premium syn"
this is about using a slightly "worn" oil which may (or may not) assist in breaking in. think "not so slippery", lower additive pack (because of previous use) etc etc instead of using a low spec running in oil
think outside the sarcasm square, i didn't post this lightly, unlike some of the replies
btw, prolly 1/2 - 1 hour on lst fill, 20w60 HDEO used for about 2,000 kms in my gently driven fatboy. i'll be using it to break-in my BSA ROCKET 3 on the stand and a couple of times around the block
ah, and lets not forget the number of race engines that used to blow when given free sponser oil. the beezer IS an ol skool race engine 3 cylinders, alloy block and rods, hi comp. pistons ( 9:1, then 9.5:1 in 1970 ), twin cams, triple carbs, individually adjustable points and timing settings for each cylinder, factory fitted oil cooler, internal paper oil filter, dry single plate diaphram clutch, triplex primary chain, DUNLOP TRIGONIC tires developed ESPECIALLY FOR IT - TT100's blah blah blah ...
and all this in 1968-69
