Top Side Oil Extractor
Would I have gotten a message indicating too much oil in the pan if it was indeed more than 8.5 qts in the pan?
I purchased the dipstick tool and took readings both before and after changing the oil. It was at 132mm.

What people forget to do, is create a vent during the siphoning process. I always crack the fill cap and remove the oil filter assembly during the siphoning. I drive the car for 10 minutes or so before as well, to thin the oil.
No problems here at all.

Unless someone has a better reason than to save maybe $30 bucks a year, I would be interested to know.


I use this handy tool from Harbor Freight for E320 oil changes and brake fluid flush, as well as brake fluid flushing on pickup and SUV.
It has a large tank capacity and creates a strong vacuum.

Mike,
Here is a page from M-B manual dated August 2007 showing approved engine oils.
My car is 2008 model and rolled off assembly line September 2007.
229.51 is DPF compatible oil.
I think 229.52 oil came later and is also approved for this engine.

This applies only to those models that have a dipstick. Most home mechanics using a vacuum oil extractor on a Benz are doing it wrong. The existing dipstick tube extends to the lowest point in the engine sump. The external suction unit should be attached to the top of the of that tube without sticking another tube into it.. This uses the full volume of the dipstick tube to extract the oil and is much faster and more complete. This is the way the dealers do it and so do I for many years and many Benzos. If you don't believe it I propose you conduct the following experiment. Suction your oil using the method I described above, then crawl under and remove the drain plug to see what you get. You may want to consider carpeting your garage with white **** after doing it this way.
Attaching to the top of the dipstick tube may require a little fiddling if you don't want to buy a purpose-made adaptor. In my case I used a drilled plastic cork.


I've heard some recommend checking the engine oil level with engine running - this would explain that!
How to know which engine models have this feature?
Anyone know who sells these adapters?
BTW, I also have a 2008 E320 Bluetec. It has a dipstick but I don't know if the gassers do. Don't know about a source for adaptors. My cork works fine. I use a MityVac canister, manually pumped.
To my knowledge all Benz are so configured. If you remove your lower oil pan in the future, look for the dipstick tube end.

Well, I tried both of these methods on my 2008 Bluetec V6 yesterday and my experience was quite different:
- At first I vacuum extracted all used motor-oil that would come out from top of the dipstick with only a tight rubber adapter. IE no small tube was pushed inside dipstick tube down to the bottom of pan as suggested above.
- Next I pushed a plastic tube inside a dipstick tube all the way to the bottom of the oil pan and continued vacuum extracting only to find out that about 4 more liters of oil came out!
Not sure what the differences in dipstick tube design in different model years are?
