Every time we change oil in our class C they charge us extra

California requires people who sell oil to have a recycling tank. I buy from Oreilly's here in town and take my old oil back to them. I was lucky enough to get hold of a 5 gallon commercial vegetable oil bucket. I can change oil on at least two cars and the motorhome before I have to dump it. Makes life easier. I keep it by the gate and grab it/dump when I go get fresh oil.
