    Q:
    Have used Quicksilver Gear Lube SAE 90 #92-858064Q01, does the Sierra SAE 30 #18-9410-2 provide same protection and quality?? Thanks, Roger Bell 8/08/15?
    A:
    The technicians at Sierra say that this oil will perform just as well, if not better than the Quicksilver gear lube. It provides excellent corrosion resistance, and lubrication. If you have any other questions, please contact the number at the top of the webpage.
