Truck is my trusty ford ranger 4.0 v6. I normally run 5w30 FS @ 5,000km OCI.
I'll be changing it next week sometime, with the next one being due probably sometime around mid-late november.
Now, i live on the canadian prairies where winters are long and cold. Temperatures usually sit around -15 or -20 celsius from november to march with the occasional cold-snap where it can get down to -40 for a week or two.
I do use a block heater, but I want to know if I am wise to switch to a 0w30 for the winter stretch.
I am still of the opinion to not veer too far away from factory spec, but if the 0w30 buys me even half a second to get oil pressure per cold start, then that seems like a good idea to me.
