Tips / how to change oil?

[A26B]

The LT5 has a LOT of nooks & crannies that take a long time to drain back to the pan. The longer you let it drain the better....within reason of course. What this also means, is that you do not get an accurate oil level as soon as the engine is turned off, or even a minute later.

A simple, good procedure.
(1) Put the Zee on a lift, stands, ramps or whatever method you use.
(2) A. Hot drain: Pull the plug, let it drain overnight,
OR
B. Cold drain: Let it sit overnight, then drain.
(3) Replace the filter, no worries about the oil cooler.
(4) Fill with 9-1/2 qts.
(5) Drive it, park it, check the oil level the next day or whenever, add what is shown low on the dipstick. Do not expect all of the added oil to show up immediately on the dipstick. Remember the slow drain-down characteristic.

Correct oil level is observed on a cold engine. A hot LT5 will not show an accurate oil level due to the long drain-down characteristic. Always check oil level on a cold engine.

Would it not be best to drain the oil while hot, then if you wish let it seep overnight?
For some reason I am averse to draining the crankcase while oil is cold. I have it in my head that the cold thick oil, would not transport carbons and other contaminants as well as hotter/warmer oil.

Maybe my methodology is flawed?

I am used to changing my own oil on my vehicles. Don't know much about this beast - so hoping u guys can tell me. I have the AC PF970C filter already, and I use Mobil 1 10w30 in my other vehicles anyway so good there. How many drain plugs are there, will I need to do anything special with the cooler or filter, how many quarts does it take? Any other hints regarding the oil change process? Thanks....

There is as many ways to change the oil as there are owners.
Mine is performed this way every 3000mi using full synthetic 10w40 Ultra Pennzoil.
1. jack up car (cold or hot)
2. drain whatever comes out in 5min
3. replace filter and add equal oil to what was drained.
4. start car and check for leaks.
5. check level the next day and do the needful.
