For ‘babyblue’ and others. Just talked with my old #1 technician at Penske. He handles (mainly) a fairly large beer distributor in Ohio. They still have year 2000 tractors& trailers, non-def after treatment crap on a lot of them;he uses ‘fluid film’ religiously on everything that needs it.Along with regular maintenance of course on everything. Probably 20-25 units in total. Just a heads up.
