New twist on S2000 oil change...

Pulled the S into the garage after being on the road, to change the oil hot as always. Jacked up the driver's side rear a little bit to help with complete draining. I realized I could do the whole oil change from under the hood, just reach down with a ratchet and pull the plug. Remove the filter first to make it easier, let it drain and went to bed. Finished in the AM. Anyone else do their oil change from completely under the hood? (as opposed to under the car)

I don't mean to hijack your thread, but I thought I'd comment on letting your car drain overnight.
Maybe I'm a little anal about minimizing wear on my engine, but I prefer to drain the oil and fill it back up with the engine still warm. Here's my rationale:
The new filter doesn't have any oil in it and unless you fill the filter up with oil (as some people do), then you're starving the engine of oil the first few seconds after you start the car,
This temporary oil starvation is compounded by letting time pass, allowing more oil to drain from critical surfaces and bearings before you start the car back up again.
If you wait overnight, your engine is cold. When you first start your engine, bearing clearances and alignment are somewhat distorted due to stresses induced by differences in temperature in the engine. I'm not sure if you realize this, but the thermal expansion coefficient of aluminum is about twice that of steel. Even if the thermal expansion took place uniformly (which it doesn't), the relative position of the bearings shifts because the crank and camshafts are made of steel. In layman's terms, there's much less wear on your bearings if you start the engine back up when it is warm, knowing that it will be starved of oil.

If you want to be A.R., I also disable the injectors and crank it over for a few seconds to re-prime. The drain valve sound good, but seems to me it won't let as much oil drain out opposed to it being removed all together. I'm not sure, and I'm not lazy (no implications anyone who uses the valve is lazy).
