Evergreen did very right by me.

Had my car worked on a couple of days ago. They got me in on time. They changed my oil when it was HOT. That's the best time. They found out my rear bearings were bad and changed them at NO CHARGE. I still had a whopping 600mi on my warranty. They found things that needed to be done in the future and let me into the service area and talk to the man that actually did the work on my car. When they alined it they let me sit in the car so iy was loaded correctly. If road noise= tire wear then their alinement was spot on. This is the first time in a long time after having my car worked on that I didn't walk away with a bad taste in mt mouth and a pain in my a$$. If you live around Bangor, take the ride. You will really enjoy the ride back. savoo

 
haha, i love your last point. score one for evergreen. i'll be getting the inski special alignment when i get the summer wheels on.

 
It was a pleasure working on your car and working with you. Its definitely a keeper..H6 Outback with some nice diggers! Let us know if you need anything else.

When the oil is hot and the car has just been shut off there are more by-products of conbustion floating in the oil. If you let your car set for the night then change your oil the sluge and other contaminents settle too. At least this is what I believe. savoo

 
The viscosity difference at temperature also makes the job easier.

Analogy time: Take a glass of syrup and a glass of water, turn them upside down at the same time. It's going to take a lot longer get all the syrup out of the glass then water. Oil is more fluid at its intended operating temperature.

 
Here is my thinking... based solely off, well, nothing.

Using any modern multi-viscosity oil it will actually be more fluid when cold ie 5w40 is 5 weight cold and 40 weight hot. Also, letting the car sit allows all the old oil to get into the pan where it will actually drain rather than stuck to the cams, oil galleries, etc.

Hmmmm..... off to Google!

 
but then wouldn't you need to literally have it sit all night on the lift/jack? even driving it 10 feet would throw all that oil back into everything

Oil is more fluid at higher temperatures.

The oil weight in multi-viscosity has to do with ambient outside temperature after the motor has cooled vs operating temperature.

http://en.wikipedia.org/wiki/Motor_oil

The temperature range the oil is exposed to in most vehicles can be wide, ranging from cold temperatures in the winter before the vehicle is started up to hot operating temperatures when the vehicle is fully warmed up in hot summer weather. A specific oil will have high viscosity when cold and a lower viscosity at the engine's operating temperature. The difference in viscosities for most single-grade oil is too large between the extremes of temperature. To bring the difference in viscosities closer together, special polymer additives called viscosity index improvers, or VIIs are added to the oil. These additives are used to make the oil a multi-grade motor oil, however it is possible to have a multi-grade oil without the use of VIIs. The idea is to cause the multi-grade oil to have the viscosity of the base grade when cold and the viscosity of the second grade when hot. This enables one type of oil to be generally used all year. In fact, when multi-grades were initially developed, they were frequently described as all-season oil. The viscosity of a multi-grade oil still varies logarithmically with temperature, but the slope representing the change is lessened. This slope representing the change with temperature depends on the nature and amount of the additives to the base oil.

The SAE designation for multi-grade oils includes two viscosity grades; for example, 10W-30 designates a common multi-grade oil. The two numbers used are individually defined by SAE J300 for single-grade oils. Therefore, an oil labeled as 10W-30 must pass the SAE J300 viscosity grade requirement for both 10W and 30, and all limitations placed on the viscosity grades (for example, a 10W-30 oil must fail the J300 requirements at 5W). Also, if an oil does not contain any VIIs, and can pass as a multi-grade, that oil can be labeled with either of the two SAE viscosity grades. For example, a very simple multi-grade oil that can be easily made with modern baseoils without any VII is a 20W-20. This oil can be labeled as 20W-20, 20W, or 20. Note, if any VIIs are used however, then that oil cannot be labeled as a single grade.

The real-world ability of an oil to crank or pump when cold is potentially diminished soon after it is put into service. The motor oil grade and viscosity to be used in a given vehicle is specified by the manufacturer of the vehicle (although some modern European cars now have no viscosity requirement), but can vary from country to country when climatic or fuel efficiency constraints come into play.
