Do-it-yourself Oil Extractor

I have both 12 volt electric pump ALSO a vacumm extractor!I find
both savers excelent tools! I change my daughters 05 jetta TDI What
a god send I dont have to mess with engine shield screws !! want to
save time ? Hook both of these items up IN SERIES . NOW TELL ME
they are NG!!TOM the retired DIESEL MECHANIC PS both items
purchased NORTHERN TOOL CATALOGHAPPY DRAINING !!

This sounds like a dandy thing for draining out the gass tanks
on riding mowers etc. that you put away for storage .

ATTN: JOSBORN and GMeekWe contacted PELA with your questions.
Here is what their representative, Allan Hum, had to say:Thanks for
bringing this to our attention. We totally disagree with the
comments posted by JOSBORN. Small engines use the same oil as
automobiles (API service classification SJ or higher). All
crankcase oil will suspend contaminates. In fact, it is a very
desirable quality. By pre-warming the oil, this will stir up and
suspend debris which will allow a greater quantity to be removed
during the oil change regardless of the method used.The whole
purpose of oil changing is to prevent sludge. If the engine is well
maintained, there will not be a buildup of sludge in the
crankcase.If sludge is present due to poor maintenance, then the
crankcase would need to be flushed out with a solvent or the oil
pan would need to be removed and cleaned. (It is doubtful that by
removing the drain plug, the less than half quart of oil would
generate sufficient velocity to flush out the build up of
sludge.)If you or your readers ever have any questions, we are
always available. We can be reached by email at:

The oil extractor will leave sludge in the crankcase. Most
mowers do not have a drain plug anymore as they were so hard to
remove and reinstall reliably. If you can immagine the plug
dropping out - if not a missle in the blade, the oil drains and the
engine burns up.george meek

I have concerns about the "Do-it-yourself Oil Extractor" method
of changing engine oil in small engines. The engine oil used in
today’s small engines is formulated NOT to keep debris and other
sediment suspended in the oil. A vehicles engine oil does keep
debris suspended so that it can be extracted via the oil filter,
however in small engines most have no oil filter. The contaminants
which settle are flushed out of the engine by all the oil draining
when the oil drain plug is removed. That, and to remove ALL the
oil, is the reason the drain plug is located at the lowest point.
However, by using the "oil extractor" instead of properly removing
the drain plug; settled debris, sediment, and other impurities will
not be adequately removed from the oil reservoir. Since these
impurities are not removed, putting fresh oil back into this
reservoir will pre-maturely contaminate the fresh oil. My
assumption is that this devise was developed by someone not
understanding the full picture of engine protection. Too many times
we try too hard to find the easy road, however much like this
devise, easier is not always better. Oz
