Test results attached, note that XX indicates breakdown,
the load indicated has to be multiplied by 6.
We did the used cooking for a laugh!! Please don't
accuse me of recommending its use as an engine
lubricant, although it is a great diesel fuel.

We found it necessary to do our own tests as I
could not access any information giving an objective
comparison. I guess some hackles will be raised by
the relatively poor performance of Mobil 1, perhaps
it has some other highly desirable qualities.

I think we are missing something here. Probably oil
temperature. Used cooking oil looks as good as the
best synthetics :) Somehow I doubt that :)

John evans,  For the purpose of evaluating the test
data it would be nice to know how the time at each
load step was kept the same for each product since
it would affect the temperature rise of the oil and effect viscosity.
