My 05 Super V/8 just turned 100,000 miles. Is the oil captive in the blower and if so, should I change it and with what?

 

I did mine the otherday just because i was changing out the leaking coolant overflow tank and i already had stuff taken apart. Youll need to take the air intake loose and move it out of the way. The oil plug is on the front of the SC.the dark circle in the pic. Take your time removing it because if it falls it would probably be lost forever. Lol. I used a length of flexible vacume line attached to a squeeze ball suction thing to get the old stuff out. (It is the stinkyest substance on earth). It took quite a bit of manuevering to get the suction line to the oil, i think there are baffels in there or something. My suction device wasnt very good so it took a few attempts but i managed to pull out around 3 oz. I think about 1 oz ran out of the hole while i was trying to get the tube in. They say it holds 6-8oz but i got as much as i could out and put the same amount back in and it runs fine. They sell the SC oil at the GM parts department at any dealership. I think they got me for $10 per 4oz bottle. I got 2 just incase.
The old stuff looked bad and smelled even worse, but i didnt notice any change in sound or operation with the new stuff. im sure its a good thing to do, but its probably not that vital.
