I use the Rotella 15w40 in my Onan 5500 watt gas generator with no issues at all.

Same here. I change it same time as the Cummins. Although, I'm in the middle of 96 hrs straight use, running 3 AC's, in 103 degrees, for the 2nd time this summer. I may need to change it sooner.

Correction. I use Rotella 15W40 in my Onan Diesel 10K. I missed the reference to 5500W
