what kind of oil should i use?
so im due for a oil change for the past 2 times i been using synthetic mobil 1 turbo diesel 5W-40 i herd from people that work on big rigs that synthetic oil is not good for diesel motor's reason 1 is cuz its to thin not sure if its completely true i don't see any leaks on my motor. people also say that i should be using 15W-40 not 5W-40? would ROTELLA non synthetic be a good choice? would me changing from Synthetic oil to regular hurt my engine?
