I just had my oil & filter changed at an independant service centre. The car is less than 2 years old. I was assured that Fully Synthethic Oil and Original Manufacturer's filter were used. After collecting the car, I drove 2.5 miles home. I checked the dipstick and was surprised to see that it was still quite black. I rang the mechanic and he told me that that's the colour of the "Special Oil" that he used. I went back to the garage and demanded to see the old filter and the new oil that they were supposed to use. I could not determine 100% if my filter was changed because it's an internal one inside a casing, but the fresh oil they showed me was light brown in colour and clear to the touch after I dipped my finger in it, so the story about the Black coloured Special New Oil made no sense. I asked them how my oil managed to go black after only 2.5miles of driving. No reasonable explanation was given and the atmosphere started to get very tense. I suspect that they did not fully flush out the old oil and possibly did not clean the filter casing, so some old oil was still left behind. It's hard to determine, how much new oil they put into it. I was charged 80 Euro for oil change + filter. Nothing else done. I'm kicking myself I did not look over their shoulder while they did the job and also for not dipping it before driving home. Considering Small Claims but not sure if it's worth it. Comments ? Thanks
