Older cars needed more frequent oil changes with "turbo" oil (SF or SG rated for the probe, for instance). I always changed mine more frequently, and tried to let the turbo cool after a run. I also tried not so drive with my foot in the turbo. What "broke" on it is that the seal to the engine is going, so that's a problem. I've seen reports of some turbos going bad in Saabs, but I'm not sure which models, and which model years. >>>Since Saab seems to be the only manufacturer with turbos, the question >>>is why? >> >> They're not.

I can speak about the cars above, probe, eclipse, vw (no turbo), and mercedes diesel. Harvey > >Dave Hinz
