I supercharged my car at 100k. Have you monitored your oil consumption? I was using about 1 quart every 3,000 using 5 or 10W 30 when I was NA (I don't know how the previous owner was with oil changes). Oil consumption after forced induction has increased so I switched to straight 30 weight except for the coldest months of the year. Now I still use about 1 quart every 3,000 which I'm guessing is good for another 50,000 reliable miles. In my case, the boost does cause some oil to blow by the rings and burn up in the exhaust but I think the consumption is at an acceptable level. In the end, the increase in performance on a MT and the good price I got for the car is worth the reliability risk.
