Once everything gets converted, the maintenance savings would be astronomical.
Fuel Savings alone will me Billons of dollars per year.
I’m assuming that the conversion is of a diesel engine from straight diesel fuel to lean-mixture natural gas ignited by pilot charge of diesel oil. While that’s highly economical based on the low price of natural gas, it also is a very efficient process thermodynamically. And since the combustion of carbureted air is smoother than the combustion of injected fuel oil, I suppose there is the potential for maintenance savings because of the lack of “diesel knock”. Are there other maintenance savings?
