I have a turbo'd '94 GS-R. Anyway, today I checked the oil and noticed it was pretty low (just bought the car last week, so this is the 1st time I've checked it). Low being the first dot. I added a tiny bit (maybe 1.5 quart) to get me to Wal-Mart then bought a 5-quart jug of Mobil 1 fully syn. I added maybe 3.75-4 quarts. Right after doing this, as soon as I pulled out of the driveway, I look in my rearview mirror to see a huge cloud of billowing smoke coming from my tailpipe. It was a whitish smoke, and increases as I press the gas. I am thinking I may have overfilled it with oil, as when I checked the dipstick it was well (maybe 1/4 inch) over the full dot. I took it easy getting it 2 miles home. Just wondering if too much oil is my problem here, guessing that it is the oil burning off. Wondering if this has any harmful effects on the turbo or engine itself. In the morning I'm just gonna drain the oil out and change the filter and fill it up again. Any suggestions, comments?
Thanks

 

too much oil can be disatrous, as in bending/breaking rods etc..as soon as you can, drain it to the proper amount. But yes, its mst likely smoking because there is too much oil.
