BMW Z4 Roadster Maintenance Day

Today was a Bimmer maintenance kind of day… after taking the car out yesterday to get new rear tires installed I had to talk the owner into doing oil and all the filters change… after all it’s been nearly a year since the last oil change I did on this car.

Interestingly enough the Bridgestone Potenza’s the car had fitted only 20k miles ago were bald. So she went with a newer Bridgestone run-flat that seems to be a much softer tire, drives smoother.

…and it was significantly cheaper price wise than the Potentza’s.

Driving the car to the tire place I noticed the TPMS was illuminated on the dash… turns out someone tried to patch the run flat…

I liked the idea of two jacks lifting the whole car up, I went and ordered a second jack for my garage. Lucky for me Sears had one deeply discounted. I picked up a Craftsman low profile 2 1/2 ton jack for $23 dollars out the door!

Driving the Bimmer I also realized that as similar as this car is to my Miata, it’s significantly different also. Besides the obvious 6 cyliner vs. my 4 cylinder, it has a bigger fuel tank too.

When I got home I also went shopping for some Air Filters. I had already ordered the oil and oil filter from Walmart previously, by far the best place to buy oil at only $26 bux a jug for 5QT and $8 bux each additional QT… and another $10 for the oil filter. I went with Castrol EDGE 0W40 Euro Formula like last time.

Walmart didn’t have the air filters. So I shopped around and it’s amazing how arbitrary the pricing is. Both online and in store. Advance Auto had it the cheapest, the Wyckoff store had both the Air Filter and the Cabin Air Filter for $23 total. (*$4 off per filter), I had some gift cards I wanted to use up so I went to the store and the price there was not discounted showing up at $33 total. So I stood at the counter and placed the order on the Internet. It showed up in their system 5 minutes later and I walked out with the same product for $10 bux less than what they sell ins tore. I didn’t get a chance to use my gift cards though… Touche!

I did some more research for the identical filters online and Pep Boys had the air filter two bux cheaper, but cabin filter was nearly double the price… and I’m talking the same exact Purolator stuff.

Anyway…

I love this Bimmer. I got to drive it long before I bought my Miata and in many ways this car inspired me to ditch a big four door sedan and start looking for a little red convertible, my very own roadster.

Much like last year the weather was kind of iffy… but the rain held off

I tackled the Air Filter first… as expected there was a lot of debris…

I don’t believe it was changed in a long time… comparison of old vs. new below:

The Cabin Air Filter was next, and it wasn’t much better. A ton of leaves came falling down out of the cabin filter slot:

So I made sure to vacuum everything in there to make it nice & clean

And the final job was to do the actual oil… first time using my new Craftsman jack, fresh after being picked up in store just minutes ago

Using two jacks makes life so much easier!

It’s amazing that this little car uses almost 7 QT’s of oil… it seemed like it was pouring out there forever:

I left the thing unplugged for a good half hour so all the oil dripped out, but when I went to button it up it was still dripping!

While waiting for the oil to drain I did the filter change on top of the engine which is very convenient!

I don’t know how these mechanics do it… it wasn’t particularly hot day, maybe in the upper 70’s F and I was sweating bullets!

Had to go take a shower when the job was done…

Filling up with oil took no time, and unlike last time when I poured 6QTs in and bought another one of which only half was used, I went ahead and poured in 6.9QT like the forums recommended. The car has no dip stick so I relied on the onboard computer for the read out. The level went up when I went for a drive. And I was more comfortable with it being over half on the read out than on the first mark like in the previous time I did the same oil change. Car felt super smooth after the oil change. I’m really pleased with the way everything worked out.

And it’s time to return the car to it’s owner… What a joy it is to drive!
