Apologies if not allowed. I am on the path to become a first time small business owner. I am a certified mechanic, but never operated on my own without an easy and environmentally safe way to get rid of fluids. I am aware autozone and other places will get rid of them, but i'm concerned with like... the amount of fluids id be bringing them? and more importantly im wondering what i should get to put fluids in.

right now i have two 16 quart drain pans with caps that work awesome but with me doing this many oil changes and fluid flushes and the like i don't think it's enough. basically, do you think 30 quarts of sealable drain pans are enough? Since the capacity is my main concern, should i just buy more of those?
