If it drops the price of a gallon of oil, bring it on. My wine tastes just fine coming out of a box.
Yep.
It's not clear to me how big these containers are -- or do they come in different sizes? Will they be available to the "home gamer"?
It looks like these are intended for the "perfeshunal" market, but honestly I'd love to be able to buy in bulk for my home shop if it saves a few pfennigs here and there.
As far as product left in the bag, I'd say it's definitely going to be a LOT less than with bottles. Anyone who's worked in a kitchen is familiar with milk, oil, syrup, ketchup, etc. packaged in bags -- they're very efficient in terms of the amount of usable product dispensed.
EDIT:
Looks like these come in 6 gallon containers. Sounds perfect for home use, honestly. My van takes 6.4 quarts at every oil change, so a box would almost cover four oil changes.
Unfortunately, it doesn't look like these are widely available to consumers yet. I found some Castrol in "Enviro Pack" packaging on Amazon, but the pricing works out about the same or more than buying in quart bottles.
It's been here for some time now. I have Pennzoil and Kendall in stock, well had Pennzoil until their base stock plants went out several months back. Virtually nothing with the pure base synthetic stock is available from them now. The common size for these are 24 quart capacity, the taps hold up well and don't drip other than just after use. Have not had problems with any leakers. The boxes for these are typically a double wall unit with extra reinforcement in the corners.
