Use exactly what the manufacture of the diesel engine recommends and nothing else.
Yes. 15W diesel oil is something of a "default" for use in medium/heavy duty trucks and heavy equipment in most of the US.... unless you're in a place like Alaska, 15W is a good "all around" engine oil for diesel engines.
A diesel engine would use 15w40 a gas engine could use 15w40 or 10w40

There is not a whole lot of difference if you are using the oil in an older diesel engine. The diesel oil of today has special additives to combat the soot buildup in the oil from the EGR. The diesel oil will get dirty a lot sooner on the late model engines. A 15w40 for a gas engine can be used in a diesel.
5w30 or 10w30 for a gas engine, 15w40 for a diesel
