Hi all, I'm a first time diesel owner and have a few questions for those of you with 5th gen Cummins trucks. What is considering normal operating temp for oil when driving around not towing? I'm usually sitting at about 199-201 on highway without towing. Also when cooling down after driving what temp do you let the coolant and oil temp reach before shutting down? I’ve heard that 135 degrees Fahrenheit is the temp to let the oil warm up to before driving, is this true? Any guidance is greatly appreciated.
Thanks,
Pat
