Last fall I replaced pistons, rod bearings, lifters, push rods and rocker assemblies. The higher numbers I figured would be there from break in, but
the flashpoint is a bit low, with just the trace of fuel in the oil concerns me, but you guys are much more knowledgeable then I, is that something to be concerned about?
I have searched out other 4.0l UOA's and seen a few with higher fuel but flashpoint was higher.
The rest of the engine has 245k miles, I changed the stuff because number 2 piston skirt broke and the lifters made it sound like a baby Cummins..
99% of the miles on this oil was highway.
