My '47 MD is my snow plow and it sits outside in the cold under a tarp, so it has to start reliably. I buy ATI 5W-30 for my vehicles in bulk from the local big truck supply place. It says "meets or exceeds manufacturer's specifications for all new cars, trucks, SUVs, etc." I've heard the stories about flat tappet damage when using oil meant for modern day engines in older engines due to the low zinc issue. I've been using this for the last ten years or so and it doesn't seem to have hurt it any. Should I be using something else instead? I don't want to use 15W-40 diesel oil since it is a lot heavier than what I'm using now. The book says to run 10W oil thinned with diesel fuel in subzero temps, but that would have to be changed annually since the summers are 90 degrees plus here. I'd been running the 5W-30 all year round and it always carries good oil pressure and starts easily. Any recommendations? Maybe use this stuff with a zinc additive?
