The small barrels hold 5 gallons each, I think bossman split the cost of the 55 with another shop, or maybe peak sell a 5 gallon container of this product.By "small plastic barrels" do you mean the 55 gallon drums? Also, nice to hear the experience with that 07 Sienna, sounds like PGL is living up to it's "lifetime" name quite well. How many miles have logged on that 8-9 year run?
That sienna has clocked 134k miles since that coolant install.
