- ]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.

- As a counter-data point, and one which I venture to guess
- is much closer to reality.....
-
- I've done countless oil changes on cars and I have YET to see
- one that has clear oil after the change. This even includes
- changing the filter and using engine flushes.
