I've come back to this thread after a couple of deep freeze cycles here in Calgary. I have no block heater of any kind installed. The X is garaged at night, but sits outside all day. At temps above 0 F (-18 C), I experience nothing different than starting on a warm day. It is when it drops below 0 F that it struggles. Well, it always fires right up, but I hear a quick ZING! sound that makes me cringe. In my mind, that sound is metal on metal due to the thick, cold oil being delayed in initial delivery to the top of the engine. Has anyone else heard the ZING?

I found a site that sells the stick on pads and am thinking of adding one for use only on the coldest days. Does anyone have a recommendation on a product from this company?

I don't know what wattage is best of the oil capacity of the 4.8.

Thanks for any suggestions. Stay warm!
