I just finished changing the oil on my Solstice this weekend. At the previous oil change I replaced the stock oil drain plug with the Quick Oil Drain Valve. For those of you who do not know what this is, you can go to their web site and read about it, as well as order one --
http://www.quickoildrainvalve.com/In a nutshell, this valve, which is solid brass ball valve is very solidly constructed. They are made to match your engine. There are 2 types to choose from for most models. The normal type and a Nipple type. I purchased the one with the nipple for the Solstice, and in fact have that type on my 300C and my Durango. It comes in handy on the Durango as the nipple allows me to attach a short rubber tube to it, and drain directly into the oil pan without removing a 20lb skid plate. The valve is operated by pulling down on the lever, giving it a turn, and the oil is released. When the oil is done draining, turn back and it locks into position with a perfect seal.
This will allow you to drain the oil without using ramps as now you can just slide your arm in there, give the lever a twist, and you're draining! Personally, I still put the car up on ramps so I can crawl around and look for leaks or bent things, but it's not needed with this valve.
My 300C has had one for 2 1/2 years, 75,000 kms, no leaks no issues no problems.
If you're interested, here are direct links to the 2 types that will fit the 2.0 or the 2.4 engines. Note, you DO need to order the adapter, as the angle on the oil pan is too tight to use the non-adapter ones.
Plain (no Nipple) with adapter - $28.95 -

The total cost to me in Canada with shipping and exchange rate ended up being about $40. Well worth the price.
