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 :)
