Are you thinking about maybe a quick redneck rinse of the engine oiling system?
Drain the oil, add a 40-60 mix of deezil/15W40, let her run unloaded for a bit?
The old timers used to do stuff like that when I was a young'un.
Problem is, everything has changed since I was younger. The oil is different, the diesel fuel is different too.
If I was going to do it, for the fuel portion of the recipe I'd use the off hwy fuel or look for "Bio diesel, or I'd use the regular crappy ass ULS pump diesel and add a bit of 2 stroke oil to make up for the low lubricity of the ULS fuel.
I plan on doing this with an old 223 ford 6 banger this summer.
