Oil rationing is officially here:
https://www.jalopnik.com/.../costco-rationing-oil.../
US Strategic Petroleum Reserves hit 285.3 million barrels last week. The minimum level allowed is 252.4 million barrels. The US consumes approximately 20 million barrels per DAY. Do the math.
We are already seeing dire consequences of oil shortages in other countries. Vietnam, Thailand, and the Philippines have been experiencing disruptions in services and national emergencies. Other Southeast Asia countries are being impacted at various levels of severity. They are our canary.
I don't know how long it will be before US gasoline supplies are affected, but diesel is already above $6/gallon and US oil refineries are already at 98% capacity. So even bringing in new oil supplies will not correct the problem quickly.
My recommendations:
1: Schedule oil changes for your vehicles, even if they're not due.
2: Stockpile the type of oil and filters your vehicles so you have the capability to change your own oil if necessary.
3: Stockpile gasoline before prices start to follow diesel's trends. Make sure you add fuel stabilizer for long-term storage.
You should have all of this done by the end of this week.
4: Prepare for the possibility of a cascading failure of the supply chain if it gets to the point that trucks can't run due to the high cost or lack of diesel fuel. I don't know if this crisis will become so bad that it starts to impact residential electricity prices, but the potential is there. I strongly suggest preparing for an unprecedented long-term energy crisis.
