Little known fact from my pyro mate.

0.5% of all fuel injected****, IN A GOOD DIESEL ENGINE, ends up in the sump, these light dilution loads are easily dispersed by the hot engine oil, so you don't get sump dilution.

with VO, you get a carbon dump in the lube oil and the alkali loading of the lube oil falls off a cliff, and puts the lube oil properties on a par with particulate metal contamination... in his words "it ****ing kills lube oil stone dead"

**** EVERY engine has some blowby, stands to reason, since all blowby comes from the cylinder, that it is not atmospheric air, but contains a little of everything found in the cylinder, from unburnt fuel to combustion by products.
