This and other domains that are used for the GWV are up for renewal.  Anyone who is interested in helping fund this work could donate to the GWV.

Oil loss has become half what it was the previous month, and the engine is running quietly more often.

This weekend I replaced the filter again.  After only a month of service I found the old filter heavy with gum and high melting point triglycerides.  So, installing a heat-sink on the oil filter is appearing to be a good idea.  The engine is still showing improvement.

The engine has been running better, with significantly lower oil loss.  So, regular engine flushes, and a heat sink on the oil filter seem to be working quite well.

Two weeks ago I had 3 gallons of WATF and 5 gallons (20L) of unused vegetable oil.  I first flushed the engine with the WATF, then I ran the unused vegetable oil through it.  Watching the draining fluid I could see globs of crud come out, but the engine did not seem to improve in performance.  Still I plan to flush the engine out every fall and spring from now on.

Blending How-to / Re: Degumming WVO

Another thing that I have implemented is a heat sink on the oil filter.  I simply rapped a piece of aluminum flashing around the filter, which was twice as long as the filter.  I changed it after a month and found the filter heavy with sludge, so I call it a success, and plan to keep changing the filter as needed.

Another experiment for de-gumming and removing high melting point triglycerides was to settle my blends for 2 weeks in a galvanized bucket.  It has turned out to also be very successful at removing high melting point triglycerides and gum.

Blending How-to / Re: Degumming WVO

This last weekend I tried several methods of water de-gumming WVO.  I was not really happy with the results.  The water came out light yellow, and there was a dark, amber, sludge floating on top of the water.  It might be gum.  If so, then it was very successful.  But, it looks like just emulsified oil.  So, I left it to settle out for a few weeks before I look at my samples again.

I have done a great number of de-gumming experiments in the last 3 years.  It seems like it will take a number of methods to reduce gum.

1] I now put about 4 gallons (16L) of WVO into a 5 gallon (20L) steel bucket, plus about 1 quart (1L) of tap water; then I put a band heater on the bucket, and the bucket on top of a hot plate, and set both heaters to 250F (120c).  I leave it over night.  The next morning I find the bucket is simmering nicely, so I turn off the heat, and pour out the translucent WVO into another steel bucket.  At the bottom I find about 1qt (1L) of yellowish water, and above that, and below the WVO is a dark red liquid.  I believe it is gum.

2]  It appears that gum precipitates out of solution with WVO proportional to how much petroleum distillate is added.  I find when the added petroleum distillate reaches 50%, then most of the gum has been removed.  However, it takes about 2 weeks for the gum to fully settle out at the bottom.

3] With the above practice now in place I have returned to blending WMO with an equal part of WVO plus diesel fuel at 20%.  Then I leave this for about 2 weeks to a month, and find black sludge at the bottom, and translucent fuel blend floating on top.  When I am ready to make fuel, then I pour this blend into gasoline at 5%, then I leave it to settle in a pressurized fuel settling tank for at least 2 days to 1 week.  At the end of the settling period I drain off any liquid that is dark.  At this time I find about 1 qt (1L) of dark liquid to be drained off.

We have almost reached our support goal for this forum.  We only need $50 more to pay for its web-hosting.
