I am in need of some chamber sealer oil for a VP215 and am having a heck of a time finding it online for a decent price and in the small quantity needed. Looking for just a quart. Anybody buy it locally around here? If so, where? Anywhere from Tacoma to Marysville would work. It doesn't have to be Vacmaster brand, just any 10W oil suited for these pumps. Thanks for any input.
