If I add the suggested two stroke oil to the diesel tank will it have any effect on the Eber heater that draws from the same tank ?
The original 40 year old perkins 4107 (8) is still running fine, will it have had any mods in recent years that will protect against these problems, I suspect it had a full overhaul 5 years ago, Hydraulics and most other things look new and the heating is from 5 years ago. Hopefully if money was spent , they would have started with the engine and gone onto the hydraulic drive and heating.
