This is just me, but I would think twice about using an oil with a TBN of just 1.6 in an application that’s known to add fuel to the oil… plus there’s essentially zero detergents to keep things from ending up as deposits in your new genset. JMHO, there are much better oils for the task you seek. Amsoil Small Engine would seem to be better suited unless you’re changing that Driven oil every 10 hours or less…
