Exhaust gas is inert. It does not burn a second time. It is also not dirty air. It is CO2, CO, HC, & NOx. The O2 content is minimal to nil. Exhaust gas, while hot, is cooler than the combustion chamber. The inert EGR gas cools the combustion chamber to reduce NOx.
Great info on which synthetic oil to use, especially on non-working diesels.

why not use a catch can to get more of the oil coming in?
