Nope, I sure can't compete with some of the oil stashes around here. Still, I have too much- and bought over a case total in the past 2 wks for the new lawn tractor!
It's a Craftsman with a 48" deck & a 24 hp B&S V-twin with 2-qt oil capacity.
For the cars:
Havoline SM Dino(all bought on sale last year for ~$1.50/qt):
5w30: 32 qts
10w30: 9
5w20: ~1.33
TropArtic Syn Blend SM:
5w30: 9.33 qts
Formula Shell Dino SL,GF-4(all on sale @ Walgreens ~$1.30/qt):
5w30: 14 qts
10w30: 18.5 qts
Total for cars: 84 qts
For the mowers:
Valvoline SAE 40 Racing Oil SJ:
~0.4 qts(lotta zinc, good for top-ups, had it for years!)
Formula Shell SAE 30 Dino SM:
2 qts(bought just before new lawn tractor delivered)
Havoline Full Syn 10w30 SM(from Big Lots)
3 qts
And I couldn't decide between Rotella T 15w40 at $8.88/gal or Delo 400 15w40 at $10.57/gal- so yesterday I bought one of each!
Both are the newer CJ-rated stuff. (mebbe I shoulda bought a gallon of Delvac 1300 too- oh well, next time
)
Total for mowers: ~13.4 qts
Total motor oil: 97 qts, minus the pesky fractions.
Oh yeah- I counted 5 bottles of SLOB too. May use a little in the mower's oil changes.
Lotta oil- but still a real amateur stockpile compared to some!
