Does anyone have experience with the 5 gallon valvoline box? I'm wanting to switch both of my vehicles over to R&P. The 20qts of the 5 gal box is almost perfect for 3 changes in my vehicles vs buying 3-5qt jugs for 2 changes and having a qt left over. I'm looking for feedback on the 5 gallon box since I've never handled one in person. I'm familiar with the 12qt garage box but wanted to make sure the 5 gallon version didn't make it unwieldly. I'll probably use an old/clean 5qt jug to dispense. Or open to suggestions on a new dispensing container if I'm switching over to the box full time. With subscribe and save from Valvoline's website the 5 gallon is under $100 with free shipping. Saves about $1/qt over the jugs and is hopefully easier to manage. I was hoping for a good black friday deal but they only threw in a free hat which doesn't really change things for me.
