Thanks, Blackhand, I'm quite aware of the meaning of
ad hominem - it was a feeble attempt at humour regarding web advertisement policy.
I stick by my earlier comment that
if it was necessary to agitate the can's content, it would be endorsed on the container. Of interest, I searched the web regarding the subject and no turbine oil supplier stated that it was necessary to do so prior to replenishment.
I rather think that they're the experts on constituents in suspension.
I've no problem with being proved wrong but it's equally important to question dubious theories, hence my comment regarding vacuum pumps. So, where's the evidence from
lubrication manufacturers?
