Theres also an Oil Time about 2 mins from my house that uses valvoline and pennzoil products. I dont know about Dobbs, Tire Plaza, etc though.
JL is owned by Pennzoil, so they use their oil exclusively even though the stores are franchised.
When I worked at a JL about 6 years ago, we had what was assumed to be regular Pennzoil in the bulk tanks for 5W30 and 10W30. At the time 5W20 was in barrels, though it may be in tanks by now. Semi-syn and PP were in boxes (think Franzia wine, but bigger), and we had a fair amount of stuff in 1 quart bottles, mostly more obscure weights for diesels and such.
