RE: Substitute for Ether
I'ed just like to post a warning/explanation on oils.
For those trying new oils as lubricants in there motors, be aware that
if the motor is run in/ well used then the running clearances have
been astablished on whatever oil you were useing.
Why is this important?
Well when new a motor may not have sufficient clearance in all
moveing/rotating places that need lubrication, dureing "running in"
these places suffer high rates of wear untill the clearance is
sufficient for the oil in use to fit the gap. At this point the wear
rate drops to allmost zero- ie: its run in.
Now changeing the lubricant to higher or lower viscosity will effect
the required clearances for propper opperation, if the new oil is
similar in viscosity to that used in running in there will be no probs,
BUT if the new oil is higher in viscosity the running in process is
restarted to establish the correct fits for the new oil.
If the new oil is lower in viscosity the clearances may be too great
and the surfaces will suffer more wear due to hammering or cyclic
movement-ie the crank rolls around the brg instead of just rotateing
within it.So increased wear and shorter motor life may result.
Now if we find after short trials that the modded vegi oil has the
desired traits we are after in our fuel its use in a new motor ie-
running in on this oil and continued use should give as good a life
as with castor.
So be aware that any motor used for testing fuels/oils is probably
going to suffer accelerated wear from higher compression settings and or
changed oil viscosity, BUT a new motor on the new fuel/oil should give
a normal life span.
