A few of my friends have done this in their trucks for many
years with no apparent problems. 10 gals of motor oil into
200 gal. of diesel. I've always felt the $10 you save wasn't
worth it. Of course, now it's $25.

This may have been covered in some distant past threads,
but if so, I
don't recall the outcome of what most likely was
conjecture rather than
petroleum engineering observation, in any event.

Thus...

My Perkins 4-154 has a sump drain which connects to a hose
with a
seacock inline. To do oil changes, one opens the seacock,
connects a
pump to the higher-than-the-engine end of the hose and
evacuates the
old oil, changes the filter and puts in new oil.

My fuel polishing setup is now complete, and is such
overkill in volume
(3.5 gpm, run for 24 hours, would recycle my entire tank
more than 50
times, at a cost of about 19AH) that I'm comfortable with
its ability
to clean my tank, regardless of what may come up the
common supply tube
(engine feeds from the same line). I've also now got a
dual Racor
setup to be able to change filters with the engine
running - both the
polishing system and the Racors have vacuum gauges to
monitor
appropriate change intervals - but that's not the point of
my post.
That big pump, recycling to that big tank, is...


Is there any scientific reason which would encourage, or
discourage,
utilizing a pump to do engine oil change waste oil
evacuations, putting
the waste oil into the diesel tank (circa 100 gallons;
i.e. ~1-2%
typical), for mixing and burning with the rest, thus
neatly not only
solving the disposal problem but also reclaiming the dead
dinos'
energy?

If there are engineering reasons against, due to the
nature of the
waste oil, are there any levels of change (more frequent)
which would
mitigate those, assuming that filter changes occurred at
the same
intervals?

I know it's useless to ask :{)) but it would be more
informative to
have sound engineering rather than conjecture in reply to
this topic...
