Keeping My Porsche Healthy: Oil Change Journey

It has been a year since I took delivery of my Porsche Cayenne Coupe. I thought the mileage would be low since I have two cars, but it has already surpassed 8,700 miles. Recently, a warning message popped up on the dashboard cluster indicating that an "oil service is needed."

I thought it was nice that the car, being a newer model, kindly reminded me about the engine oil change. However, I later realized this was just another one of Porsche's clever marketing tactics. I plan to address this topic in a separate post when I get the chance.

As you may know, purchasing a new car no longer comes with a service coupon for an oil change. Instead, you either have to buy a warranty service package that includes oil changes or pay for the oil change at an official Porsche service center, which can be quite costly. However, is the genuine oil significantly more expensive?

Not really. I use a popular Mobil 1 product. Given that, is there really a reason to spend extra money getting the oil changed at the official service center?

Instead, I decided to choose a product that aligns well with my driving patterns: high-quality synthetic XADO engine oil. I visited Motor Labs in Ilsan, a well-known business among car enthusiasts that primarily deals with "XADO" engine oil.

It seems I really neglected maintenance; the engine bay is quite dirty. When I used to wash my car myself and take maintenance seriously, there wasn’t a speck of dust in the engine bay. Seeing it like this is a bit embarrassing.
I immediately applied a full PPF (paint protection film) and have only been using the local gas station’s automatic car wash, so I haven’t had many opportunities to check under the hood. I realized I need to pay more attention moving forward.

So, I chose the best engine oil available. XADO, recognized as a top-tier synthetic oil, not only offers great basic performance and long-lasting viscosity but also contains a metal treatment restorative agent that receives good reviews for engine protection.

Now, let’s see how the process goes. First, I’ll remove the engine cover... then I’ll take out the still clean air filter. The air filter size for the Porsche Cayenne Coupe is quite large, and I need to replace the oil filter, which is a bit tricky.

To remove the oil filter, I need to take off the strut bar visible at the front of the engine bay. Now, let’s begin the main work. By the way, Motor Labs not only removes the existing engine oil but also opens the oil drain plug and injects flushing engine oil to clean the inside of the engine.

Since my car is new and this is the first oil change, I asked to skip the internal flushing. However, if the car is older or if it has exceeded the oil change period significantly, I recommend doing the flushing.

To ensure all residual oil is removed, they use an air injector during the process. This seemingly simple task is crucial because mixing old oil with new engine oil feels a bit unsettling.

I also get to see the Cayenne Coupe's undercarriage for the first time, and the undercovers are quite thorough. However, is that cover under the engine bay made of carbon? The pattern is unique, right? Anyway, I’m not sure about that.

I don’t see any oil leaks; it looks very healthy.

However, the oil is pitch black. I usually don’t let the first oil change after taking delivery of a new car exceed 6,200 miles.
This time, I really delayed it.

The last drops of oil are being pushed out using the air injector I installed earlier.

The new oil filter gets installed, and since I cleaned the filter cap beforehand, there won’t be any residual oil mixing here.

After removing all residual oil, they take off the washer used on the existing drain bolt and replace it with a new one. I didn’t know this, but it turns out it’s a one-time use. It’s a slightly bulging ring that gets compressed when the bolt is tightened to prevent oil leaks. You definitely shouldn’t reuse this.

Finally, they tighten it using a specialized torque wrench at the specified torque value. This step is important; if you tighten it too much, it could lead to oil leaks. Be sure to check this carefully.

They also replace the air filter with a new one; it’s huge, right? The price difference between the genuine Porsche filter and compatible products is noticeable, but using compatible products is fine.

Just make sure it’s from "Mahle," and check the manufacturing date. After all, it’s the same product that Mahle supplies to Volkswagen as OEM.

Now, let’s start pouring in the XADO engine oil. Before replacing it, I turn the can upside down to ensure the metal treatment restorative agent mixes well. According to the XADO Korea manual, I should shake it well before pouring.

These detailed processes happen at Motor Labs in Goyang, which specializes in XADO engine oil. They perform the work professionally and according to the manual. As a result, they can't complete many jobs in a day; it takes twice as long compared to other products.

They also topped off the washer fluid and added the engine oil additive provided as a service when replacing with XADO’s premium engine oil.

After completing all the work...

The last step is cleaning the engine bay, which now looks as clean as a new car. From now on, I will take care of it myself... I’m reflecting on my past neglect.

The exterior looks shiny, but honestly, my car wash routine has been limited to quick machine washes that just remove moisture without any waxing. However, the PPF does offer good protection.

On my way home, even though I didn’t switch to sport mode, the accelerator response feels a bit quicker. Is it just a placebo effect? Anyway, I replaced the engine oil with the premium XADO oil, and added the engine additive, so my Porsche Cayenne Coupe should be healthier now.

I’ll drive it more and provide an update later. After about 3,100 miles, I should be able to tell if the viscosity remains consistent or if it has thinned out.
