This will be my first time changing oil using an oil extractor, the result was impressive and better than what I expected. The following will be the step by step procedures, please feel free to correct me if anything wrong!
Oil Container (optional, can hold more than 8.5qt)
Mobil 1 Synthetic 0W-40
Find the location of oil dipstick and filter element
Using 12mm Allen wrench to remove filter cap
Clean oil filter and put the "O-Ring" on place indicated
Extract oil from oil dipstick
The oil extractor I have is a 6 liter, in this case I'll need to remove some of the oil in the middle.
While doing the tube removal be careful the oil will leak on the car or floor, use microfiber towel cover the fender so the tube won't scratch the paint.
Replace oil filter element
I'm not sure which side is correct but both end are identical besides the line marked inside, I placed it in with AMG(or part number) label facing out. (The other side is "blank" just so you know) ---> correct me here if wrong!
Place it back in here!
Refill new/clean synthetic oil 0W-40
After all these steps, start the engine and let it run for 5-10 minutes (or drive around your choice)
* It will be better to warm up the engine before getting the oil change, I let it run for about 5 minutes, once the temperature reach around 90C I continue the job.
* Put a towel or something soft on the fender where the oil extractor tube lay, the tube does scratch the clear cost and might cause light swirl (from my previous experience)
* While removing the oil filter make sure you don't touch the metal part surround, it's hot, don't burn yourself.
* When finished, check if you put the oil dipstick (red Cap for AMG) back.
* Using a transparent oil container so you know how much oil already extracted, then you'll know how much new oil to put back in(might not be possible to extract 100% of the old oil, that's why you need to know how much to put in so you won't overfill)
* For non-AMG models, it is pretty much the same procedures as above besides you will need to remove front
engine cover to get access to oil filter, also use different filter element, and dipstick instead of a red cap!
It's a 30 minutes job, using oil extractor will make life a lot easier. It won't save you tons of money but will give you a piece of mind since you know what oil and filter you put in.
At the end, I extracted about 7.7 liter (8.13 qt) of old oil out of 8 liter (8.5 qt), result is good, no issue so far. You won't have a complete oil drain by extracting it, but sacrificing the 0.4qt will save you a lot of time, pick your favorite way to do an oil change!!
