M6 oil change in the C5

[Fire22]

Changed the fluid in the M6, the car has about 60 000 km on it but I wanted to change out all the fluids since I bought it last year. I read good things about AMSOIL, so I decided to try it.

First get her up in the air. I used ramps up front and blocks in the back to lift the car about 7" off the floor.

The car should be level so I put a level on the sill plate to check, I am not sure if this is a good way to check or not.

Next, get everything ready first. The manual states that an overhaul uses just over 4 quarts, I drained out 3 and put in 3. That pump in the box is the best tool for this job

I like to remove the fill plug before draining to make sure I can get oil back in.

Here is the drain plug

I let it drain completely, then wiped everything up and replace the drain plug, torque to the specified amount. Then start filling until oil runs out of the fill hole.

Here is that pump

When full, put the plug in and torque it. By the way, raising the car 7" is barely enough for me to work comfortably under it. I really need a lift.

Awesome DIY article. Good pics and details. I am looking to replace the fluid in my M6 as well. Thank goodness I should have a lift available to use.
