Maybe! The one I drive in the spring is set up similar, it’s a 600 Quad. It was very stingy on oil when it was brand new but did seem to increase its oil consumption and make it darker as the engine seasoned. It was two or three years old when it got the power module, so I can’t say one caused the other. We have shortened the oil change interval down to 200-250 hours. I would consider its oil usage very modest and normal for 4000 hours of mostly hard work.
The interesting thing about Steinbauer power modules (if?) that’s what you are using, is they in no circumstance increase fuel rail pressure or initial injection timing, instead they add duration time to each one of the micro injection pulses of the electronic injectors during the power stroke. This leaves the engine with an almost identical operating personality.
For what it’s worth I know people that had one of those engines on extended oil change intervals in a combine at standard power and it blew up.
