Another thing to stock up on - lubricating oil

Looks like availability is going to be tight - two headlines from industry websites:

• Lubricant Additives: Not Enough Supply to Satisfy Demand Creates Need for New Supply Chain Strategies
• Covid-19 and the shortage of raw materials for the lubricant industry

You are thinking: "Oh, that doesn't affect me - I go through a can of WD-40 maybe once/year"
How often do you change the oil in your vehicle?
How much does it cost to run the truck that brings groceries to your local store?
What about the oil-change for the Amazon truck?

Like ripples in a pond...
