Oil Filter Question

[ClassicVW_imp]

I usually buy what supplies I need all at once for my winter lay up or spring opening up services. Sometimes I buy a bulk order of oil filters for my two or three bikes off the internet. If you used a charge card or debit card, there will be a record of purchases you could access and then see if the oil or filters are still on your garage shelf to compare what was bought and what is still there.

Alternatively, do you still have the used oil in a container or can you recall disposing of it?
