Hi, everyone...noob here...been lurking for a month or so...
My company recently had installed a 250kW emergency generator, with a Cummins 6 cyl natural gas engine. Since I am one of the techs responsible for running it weekly to take readings, check the oil and coolant, etc, I read the maintenance manual fairly carefully. The only oil Cummins specifically recommends is Cummins Premium Blue (15W-40), which I believe is actually Valvoline Premium Blue. The problem is that neither of these is readily available locally. The local truck repair shop only sells Rotella (for that matter, so does Wally World). Is this an acceptable oil to use in this motor? If it fails, the cable TV goes out, and over 100,000 people will be mad at me...
Thanks
