    No, I'm not a saleman for Mobil. I have been very happy with this product and wanted to share with OSO members. I used it in my Merc 502 and loved it! Will use it again in my 496 HOs when I get my new boat!

    I'm buying Royal Purple SAE 40 for $5.99 a quart (when I buy it by the case) from my local speed shop. I am getting less oil seepage/leaks with the Royal Purple compared to the Mobil One.

    I hope u mean 17.95 per 5 quart jug
    cause its 17.88 a jug for 15w-50 or 10w-30 here in NY
