As I decided to switch to running 15w-50 Mobil-1 fully synthetic in my Merc 3.0L, the guy at the Marina shop was telling me I should buy the Quicksilver 25w-40 he sells, because they found everyone who runs fully synthetic was getting rust and other corrosion in their engines after winterizing them. After a few years, they start losing HP because the rings and everything erode, and don't seal properly, and the cams and lifters wear out, because it doesn't stick to the surfaces inside like it should. He also said there isn't enough Zinc in the Mobil 1 like Quicksilver, so rust will also occur. I thought Mobil-1 has plenty of Zinc compared to the OEM oil. Something seems very fishy about this.
Is this just a BS sales pitch, to get me to buy oil from him?
