Its a good read but id add one thing , an worry about one mentioned .
The wear in period for a motor of 10,000 miles or so is pretty acurate except if you use chrome molly rings . Id stick with the old school oil as you mention like 10-30 for about 30,000 miles . chrome molly dont wear in ( seat ) the rings for shit .
Wall mart oil , you say it is from pennizoil ? that worries me , iv never seen a more sludge making oil then pennzoil . having rebuilt 100,s of engines that has been a clear observation . For the record pennzoil lubricates find its just a sludge maker for some reason .
