| Rotella Synthetic Went to change oil (from the previous owner) Wanting to run Rotella Synthetic. Truck calls for 15-40 conventional oil. Only thing I could find,was Rotella 5-40 synthetic. My question is, Is that exceptable? Do they make a 15-40 synthetic? Live in the mid atlantic region,where it does not get too cold nor too hot. I'm thinking the 5-40 would be ok. What is the opinion here?. Thanks for the help
