Engine Break-in

[jimnance]

Run 'em hard. I had about 500 "normal" miles on mine when I hooked up my big fifth wheel and hammered down. Pulled the hills at 3,000 RPM and did everything but lug the engine.



I now have just shy of 4,000 miles on the engine and have used about 1/2 quart. Most of that was in the first 1,000 miles. Since then oil use is almost undetectable.



If you baby the engine the first 500 miles you may have oil consumption problems later on. You need the high combustion pressures to help with the ring seating.



I think it's pretty hard to screw up the break in. Steel liners and hard rings are a pretty good combination seating wise.



Low compression engines have more problems with ring seating to to low cylinder pressures. I'm talking gas engines. With diesels the cylinder pressures are already high.

Can't complain about that (runnin' 'em hard). However, the word I am getting from "inside" sources is that Edge and competitive products are not close to getting it right when they try up the common rail power. Seems the problem has to do with fuel pressures.
