I ended up going to ebay and buying every 25 dollar bottle of 5w-20 VRP I could find (5 - 5 quart jugs) I bought the next years worth for me (5 jugs or 20k miles worth of driving.
edit: went and looked just now and all the ebay sellers have jacked prices now or removed their listings.
Honestly, Amazon and Costco are becoming the go-to places to buy oil, in the case of Costco it's a different label of Warren slop as to Kirkland vs Supertech. I already enjoy the slightly lower price of Costco gasoline.
I've got a stash that has me stretching my oil change intervals to the longer side of things, I thank the Deals thread sometime about a month ago for some to stock up on. If the price increases are finally here, maybe the floor has been reset. Ask the old-timers about the permanent price adjustment of antifreeze.
Who said that? Have you shopped online on Walmart.com?
Walmart has better and faster (same day) free delivery than Amazon. I have a friend and we were stocking up on oil he said that while he waited for an Amazon oil order, he placed and received two Walmart oil orders and he canceled the Amazon one.
Then why do 3 to 5 year old oils produce terrible oxidation test results compared to new oil?
The bottles collapsed? Well there's your hint...
You're so close.
