Ah, there you are, Clyde65. I was hoping you'd make an appearance to help yourself out after your ridiculous statement of using xw-20 weight oil "at the expense of long term protection." Apparently you have not done your homework once again.
Auto-Union, I am doing exactly what you're saying on two Hondas now with no ill effects. No leaks, zero consumption on one and 1 quart over 10k on the other, and great fuel mileage. Been doing it in warranty too. I must be crazy, or I must believe in those that have come before me on planet BITOG.
