My vote is for Schaeffers 5w40 synthetic. I can get it for $12.75/gallon.

No......don't think so, but why go back, Rotella is an excellent oil. Do a google search and read on..you will see for yourself. Many places offer it including Walmart, well some Walmarts. Also if you have a Menards in your State, the oil is on sale.

why are you guys running 5w instead of 15w which is what the owners manual says? I don't know much about the diesel motor, just looking for some info. thanks for the responses beforehand!

Much thiner when it is cold. Such as here in Michigan it was 1.3 degrees F the other day. 15 is like tar and 5 is like honey at that tempature.

Mobil1 5W-30 isn't a good choice for your 7.3 IMO. The weight isn't ideal and neither are the additives. You want to stick with a 5W-40 diesel rated oil. I use the Rotella myself.

It depends on what the second number is. The first number stands for winter viscosity and the second number is the hot viscosity. You want to have a 40 for hot viscosity for a 7.3.
