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!
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.
is it ok to run 5w in the summer (ie 100 degrees F) ??
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.
02 Stroker..................Im in South Florida and even in the winter, well not this year, it doesn't fall under 70* and you know how hot it get here in the summer, plus the humidity............Use it, excellent oil, year round. I think it's about 19.99 / gal at Wally World.........
