Practical – A big boy toy?

Several years ago Bonnie and I splurged on a vehicle most would consider having very little practical value. We were looking for something which in a few moments of free time could give us a sense of freedom, a conduit for quickly and momentarily releasing daily stress…a mini-mental vacation if you will. This sounds like a tall order for an automobile and it no doubt says more about us and the American lifestyle then it does an actual vehicle.  Still, either through our selection process or luck we found such a vehicle in the form of a used Mercedes Benz SLK sports convertible.  An hours drive on a beautiful sunny day soon results in smiles and forgotten stress.  If it doesn’t happen quickly enough I simply press a little harder with my right foot.

Passengers follow the star

As transportation this SLK has been more practical then we expected. We’ve taken a number of trips in it and it’s small luggage capacity is a blessing, simplifying packing to the essentials.

SLK – The trunk, with top folded in, is not very large.

Back in the days, before working on an automobile required an engineering degree, I use to do the majority of my own vehicle maintenance — I enjoyed that process and still do.  Going through the careful mental and physical process required to complete a job fixing or prolonging a precision piece of equipment can be much like meditation if your mind is in the right place.  These days I limit most of my tinkering to preventive maintenance on the SLK and our lawn equipment.

Note: If I had my career path choices to make over again I’d enjoy design in some way vs. IT. I find beauty in well designed things, be it systems, machines or architecture.

For my annual pre-spring maintenance routine this past weekend I grabbed a camera to take a few shots during the process.  Now I can bore you with the results. :-)

Spring – 3.5L V6 due for oil and filter change and air filter check

Beneath this pretty plastic lies the SLK’s heart – a 3.5L V6 engine. The metallic finned piece in the center is the Engine Control Unit (ECU) placed in this position for cooling purposes.

Draining the old oil out using a fluid evacuator.

Not your standard drain the oil via the plug in the bottom of the oil pan. The recommended Mercedes Benz method is to extract the old oil through the dip-stick tube using a fluid evacuator.  A few pumps on the evacuator gets the oil started and then it’s just a matter of waiting. No fuss, no muss.

Placing a wrench on the oil filter for removal.

With a well designed engine compartment the oil filter can be access from above while the engine oil is being removed.

While the oil filter drains a new one is ready to be put into place.

Out with the old oil filter and then in with the new one. They look different because they’re different brands. New rubber gaskets and O-rings are also added.

Once all 7.5qts of old oil is in the evacuator chamber a valve is switched and the oil is transferred to an used oil container to be recycled.

A single value flip allow the used oil to be transferred to a container where it can then be taken to a oil recycling center — a local auto-parts store.

New oil is added through the engine oil fill cap – 7.5 quarts.

New motor oil is added — Mercedes recommends Mobil 1 synthetic oil so that’s what I use. With the limited milage this vehicle gets (3000-5000 miles per year) I usually only change the oil in the spring.  I do however make sure and run the car regularly to evaporate water/moisture which may condense over time.

Removing the plastic cowl which houses the two air filters.

Next comes an air filter check which requires removing the plastic air filter cowling.

Checking the “Green” air filters.

The air filters (2) are “Green” both in color and brand name. They are life time filters so only require cleaning and re-oiling as required.

Spring engine maintenance all finished.

Putting everything back together, with still lots of sunny day left, it’s time to find some where to ride for lunch — perferably a place at least an hour away! :-)

Wow, sure is a beautiful car Earl. And that fluid evacuator – how cool of a thing is that! I have never heard of those before. My experience and knowledge of oil changes is crawling underneath the car to try to find some oddly placed plug that you wrench out to have oil pour all over your hand, and hopefully into a readily placed pan and not on the driveway. Hence, all of my self oil changes have stopped! :-)

Leave it to an elegant car to have an elegant way of having its oil changed!

There’s something about having a “special” car that does a soul good. Although that feeling is most likely engrained by years of marketing exposure I think there is some validity to it. I’ve got a 1989 Mustang GT that I bought brand new, and I keep promising myself that I’ll drive it more. Hopefully as soon as I’m done living in a construction zone I’ll be comfortable keeping it at home again. Right now it is safely tucked away in a storage unit, which I try to visit a few times a month.

I think we’ll need to plan a road trip for one of these upcoming weekends and give our machines a workout!

I’ve never been a huge car fan but I can well appreciate the allure. That’s a nice looking car you have there Earl. I have no doubt it gets the adrenalin flowing. Perhaps I too would become hooked if I was to drive something like that though I suspect a Kombi is more my style.

May I say, as someone who is totally useless when it comes to mechanical things, that I am impressed that you self-service such a vehicle. And your photos are worthy of being in some top class motor vehicle magazine.

Neither photos nor stories are boring. Keep them coming Earl.

This post and the images made me smile. I’ve never had a fine car like your but I did have one of BMW’s finest sport-touring motorcycles, the BMW1100RT. I took good care of that motorcycle. And, I can relate to the adrenaline rush something like this gives. My ride to work in the morning would take about 25 minutes but it sometimes took me 2 hours to get home. Great way to clear out the head.
