After the wall marts around here ran out of Synthetic rotella for like 3 months I all ways try to have at least 3-4 gallons on hand.
I have a little bit of Mobil 1 left form my super hord I built up in 1999. I still have about 2 gallons of SJ,SH rated mobil 1 5w-30 weight and about 1 gallon of SJ rated 15w-50 weight M1 left.
1999 was when you could get 5 cases of mobil 1 when it was on sale for $100 and have change left over to fill up your car with gas.
I have about 2 gallons of Mobil 1 synthetic AFT that I won't use because my transmissions leak.
I stalked up on advance auto brand AFT, got a few gallons.
Advance auto parts brand AFT should be repackaged valvoline.
I still have 3 gallons of SM rated mobil 1 I'm trying to cut in with my good oil and about 3 Qt's of MX4T.
A modest stash of about 60Qt's (just motor oil, not counting ATF) mostly in gallon jugs.
My next oil haul, I will be buying gallon jugs of 5w-40 weight Synthetic Shell Rotella T.
And maybe some MX4T.
I buy every thing possible in gallon or 5Qt jugs, cause when there empty they make great diesel fuel jugs.
The oil is cheaper in the big jugs, plus when its done I get a free fuel jug. win/win for me.
Plus I have a nice diesel fuel and gasoline stash.
