May 2013 Oil Change on the Z4
It was time for another oil change. This time on the wife’s Z4 Coupe. I performed several other maintenance tasks on that Saturday morning. Don’t you love weekends? This is a straight forward and relatively easy task.
The first thing is to get the vehicle safely up in the air. I drove the car onto a couple of pieces of cut 2×10 to raise it high enough to get my floor jack underneath. I stabilized the car with wheel chocks on the rear, pulled the emergency brake, and put the car in 1st gear to prevent the car from rolling back. I raised the front and lowered it onto some wooden ramps that I built. Then I went to the back of the car and raised the rear and lowered it onto a pair of jack stands. Next, I went back to the front and lifted it and then lowered it onto another pair of jack stands. Note: I put my wooden ramps under the car and my jack followed me back and forth underneath the car as I moved from front to back for an additional level of safety.
With the car completely off the ground, I could perform all of the maintenance issues. The oil change procedure follows:
1. Remove the oil filter from the top of the engine
2. Remove the oil drain plug with a breaker bar with socket and drain the oil into an oil catch pan.
3. Replace the oil drain plug with a new crush washer installed. Tighten using the right amount of torque with a torque wrench.
4. Install new oil filter with new O-Rings.
5. Fill engine with new oil.
I also performed a gearbox oil change, differential oil change, and brake fluid change on that day. Easily a $250 savings on labor. Probably more.
