Yesterday I called Pep Boys, because I saw that they had a bunch of Castrol Startup on their discontinued rack along with Havoline 40HD, Valvoline 5w40 etc, All the oil was still priced at its shelf price, so I called and asked if they could work me a price and Id buy all the Castrol they had for one price, I talked to the assistant manager, to my surprise this is what he said, NO, we never do that we will leave the oil there and if it doent sell then we will give it to our service dept to use in the cars that come in for oil changes, but I said dont you all advertise "specialty Pennzoil" changes. He said we can exchange for "comparable " brands, and I said what about the straight 40HD, you got cases of that, and no cars really call for that. He said We'll mix it in or use it for top off, our customers dont care. We never put the oil on discount, our service dept can always find some way to get rid of it. I know th qiuckie oil change places are evil, but this guy was straight up with it. The dealerships are no better, from experience. My wifes car was under service agreement to 40,000 m and when I took it in for the 30000 m service which was trans. fluid change when I got it back it was still dark red and still smelt used, I called them and said you guys didnt change this, no way. They told me they did, fluid and filter and they had records so dont worry if you have any trouble come see us, will back you up, gee thanks. I changed it in 50000 and the filter was black, there is no way they did it. One more story, A good friend of mine works at a Chevy dealer in Pennsylvania, he told me they use 10w30 in all their oil changes, regardless. He also said When he worked for Ford they did record work they never did, and he laughed when I asked him if they ever check oil anlysis over a blown engine for correct vis. when its under warranty, he said why. Ford pays them big bucks for warranty work. Tell the customer its not covered they go someplace cheaper.
