What do you mean by bulk?
Mobil 5000 (or any oil) is the same in a quart or a jug. But if you buy a 55 gallon drum of Mobil motor oil, it's not the same. Per the Mobil website, 5000 contains 16% more detergents than their bulk oil. By bulk, they mean an oil truck, or the barrel.
I'm not sure if Formula shell is the same in quart as it is by the truckload.
Honda oil by the quart is made by Mobil and is like Exxon Superflo or Mobil bulk.
Honda oil from the bulk tank could be the same, but it could be any other bulk oil like Chevron or Formula Shell or whatever else the dealer feels like buying.
I guess the only answer is that it depends, and you'd have to ask at a dealer.
Anyone with jiffylube/vioc experience?
Same formulations same batches just different packaging. Castrol Syntec Bulk and bottle is the same. So is Pennzoil and the other major brands. Mobile offers a different product but it is not advertised nor labeled the same as the bottle shelf product Mobile 5000(yes I spelled it like a coastal alabama city ).
