In a 2000 7.3l powerstroke, what engine oil should I be using in the winter. Here in the Toronto area it usually hovers between 0 - minus 10 celcius. But it can get colder. My manual says I should use 10W/30. can I use any 10/30 or does it have to be a certain type?
The reason I ask this is I changed my oil last week and put in some Castrol 10W/30, and this week my truck started knocking and ended up stalling on the road. The temp at the time was -15 celcius. The only thing that I've done differently is change the oil to the 10/30.
