Ultra-low sulfur diesel fuel affects lubrication

[Al]

Hi Jim,
Yes I believe you are talking about Steve with a BMC. The
technology of using straight vegie oil is really not a proven one.
The vilosity of the oil is much thicker than biodiesel or
petrodiesel. He succussfully coverted his bus to run on straight
used oil but only time will tell. I am sure he believes in the
technology and from what I saw in his pictures, he knows what he is
talking about. A very nice professional conversion for sure.
Certainly straight vegie oil will have even higher freeze temp than
biodiesel or petro diesel. But people running those systems usually
have some form of heating mechanism to get the oil upto engine temp.
Then they swap off of petro diesel to staight cooking oil. Before
they shut down they swap back to petro diesel to clense out the
system so it will start again next time.
