- Well, I do my own oil changes on three cars and each time the oil is clear for
- weeks/months afterwards. I do use a flushing oil every other change (not
- additive, real flushing oil) on the two with hydraulic tappets however, but the
- other is just as clean. The cars are all high mileage, one is >120k miles.
-
- I'd be wondering whether they didn't change the filter too.... Try smelling
- the oil ! Used oil has a very distinctive 'burnt' odour compared to new oil
- IMHO, due to dissolved carbon and petrol.

- Hope this helps,
