I am not sure how many years worth of oil I have. Maybe 3-4 years if I had to guess.
I do know I have 40 gallons.
I have quit buying oil, but will still get it if it is free after rebate.
I recently sold about 10 gallons of oil for over $100, making about $70 profit.
My current stash has an average cost of $0.28/qt (16 qts of syn blend, 36 qts is synthetic).
The 12 car's that I'm doing for friends and relatives and mine oil change q 4-6 months interval,about 140 quarts assorted weights mostly 0w-20.Those oil bought with rebates,sales. Mostly QS of menards.
Zippo. With generally good availability and online shipping & tracking, no need to hoard anymore. Unless a refinery blows up, but most would be S.O.L. anyway.
One to two oil changes on hand per vehicle. After I change the oil, I have about 5 months before the next oil change and I should get to Walmart in that time to buy oil.
2-3 years in reality. I drive very little; already worked from home so a stash of 2-3 filters and a couple 5 quart jugs will see me through my yearly oil changes for a couple of years. Typically I buy filters 5-6 at a time if something is on sale at rock auto. Sometimes this leaves me with a stash of them I can't use but my last 2 vehicles have used the same filter even though they were 19 years apart in mfg so I got lucky. Wiper blades not so much
Here in So Cal we go through wiper blades because they dry rot from lack of use.
I have about 12 years worth of HDEO for the Subarus, and about 2 years worth for the Ford. Because if anything goes down, everyone knows you want to sneak out, and:
