I know the requirement for my 2016 etec 200 HO is xd 100. Thats all I ever used. I order 3 gallons at a time and it was taking abnormally long for it to come in this time. I really needed to pre fish today and thought what the heck a little quicksilver would be ok just for today and about half way through my trip the alarm went off and went into idle mode because the oil level was too low. Is it because the quicksilver was so thin and not thick like the xd100? It was still showing 30% on my gauge but it could be off.
