Lol! Largest stash I had,was way back like 2006? Walmart had clearance havoline dino. Mostly 5w30,some 10w30..it was like mad cheap I don't remember price it was under $2 I think...I made 2 trips buying it all up. I had like 79 quarts. Kept them in milk crates.
The local AutoZone had Pennzoil Ultra Platinum clearance, like 2013. Bought up what they have left .was like $3.24 quart that area,5w30. Had I don't remember, like 7 quarts. Used the Pennzoil Ultra Platinum up over year half.
Used the havoline in-between,mostly 2017-2020.
Won't whored no more. It's too much.
And time frame,additive fallout,oil expiration ..no more
Interesting enough this past year,local gukf station stationed just before I95 south here Stamford CT ..I found old containers mobile drive Inback!
But for $10 containers near...believe it was copyrighted 2005 or earlier like 2002..that's alot for that.prob still their inback
