Just saw an old ad on Google titled '1983 Castrol XLR Motorcycle Challenge'. It must have been an oil made for motorcycles. I'll use it for chain oil in my powersaw.

I also found 2 quarts of Castrol 'Motorcycle Oil' 30W in cardboard cans. I think our metric system appeared about the time cardboard cans disappeared. My uncle may have had an 'oil' museum.

I recently cleaned out my uncle's garage and found bottles of Castrol XLR, 10W-30. Is this a discontinued brand. If so, it must be quite old. Is there a shelf life for motor oil? Seems to me if there is, there should be a "best before date" on the container but I've never seen one.
