Well, after two weeks of waiting, my free samples of lubricant arrived from Shell Canada. We asked for samples of 4 different lubricant products.
These lubricants are candidates for films on small moving parts in a small part of a very sensitive seismometer. One drop of oil will be applied, and the excess wiped off.
The shipment weight (mass, technically) was 79.3 kg: they sent 5-gallon buckets of three products, and a box of 24 1-liter cans of the fourth.
I think we've got enough of these for now.
Moral: If you feel you're paying too much for gas at the pump, take a hint, and ask for some free product samples next time.
