Guys seriously? I been changing oil for better part of 30 yrs, on vettes, my crossfire, grand national, iroc-Z just to name a few, the topsider thing is for dealers to save time PERIOD...if your too lazy to get under your car. Go to jiffy lube and let them rape you. Personally, I like it under my car, you can inspect other things that might not look right. Something you will definitly miss topsideing it. And, they make oil plugs with magnets... Wanna guess why? Geez. Get your a$$ under the car and scope thing out, change the oil while your there...
