I went to get my oil changed today I scheduled an appointment for 10 I got there a half hour early which wasn t an issue. I asked how long the wait would be they said roughly hour or hour and a half I said ok I will wait . So after about an hour goes by I get a call saying they couldn t change my oil the drain plug was to tight and whoever did it last may owe you and oil pan which is funny because I did it myself and I know it wasn t cross threaded or over tightened down. So I go home a little frustrated I climb under my truck and they had changed the oil filter before they even drained the oil which isn t usually how it s done and the oil filter appears to be leaking. So I checked the drain plug and it was just snug not super tight from what they were saying. So I called and asked if I could just get the oil and do it myself at this point I m wondering what was going on and why they didn t want to change my oil. So they gave me the 8 quarts of oil they were going to use to change the oil in my truck with free of charge and it s not even the right kind of oil my truck calls for. So now I guess I ll just go buy the dextos 0w20 fully synthetic my truck calls for instead of the cheap synthetic blend they were going to use that wasn t dextos rated . I m just wondering what s going on in the shop over there unbelievable
