welcome
too me... its nice you can buy that. when i was changing my oil and doing my PMs on my car, i would have jumped on it.
at work they buy some of teh 1 qt bottles and some of the equipment will use 3~5 its, but to me, the bottles are more garbage/plastic to deal with. Getting a 5 qt jug would be better or 55 Gal drum. we have pumps both hand and pnumatic to transfer and empty the tanks, but no one wants to use them other than for the big quality work.
