Thanks for the advise. I bought the Quick Silver Premium Plus. I hope this doesn't sound like a dumb question, but does it hurt anything to pour it in my oil tank that is half full with Yamalube 2M.
Run your oil resevoir down as low as you feel comfortable, then add that Quick Silver.
I did this years ago when I switched from using regular Pennzoil to 100% Pennzoil Syn, did't hurt a thing!
Ran the tank down to about a 1/4 and poured a gallon of Pennzoil Syn on top, that was in 2003.
