It's the Genuine Part - Fits Large Selection of Mercedes Cars
Size: Pack of 1
There is no doubt that I like to take care of my vehicle. Therefore, with a car that calls for oil changes only every 10,000-13,000 miles, I want to be sure to use the approved oil filter that can survive that long.
First, let me put this early in the review. I had had the Mercedes Branded and Box part side by side with this one. They are identical besides the labeling (and part of the labeling is the same as the Mercedes branded one still has the Mann logo and part number too). They are identical because Mann makes this filter, their own brand, and the filter for Mercedes. They are truly one in the same.
These Mann HU 718/5 have a beautiful, strong construction, and indeed they are actually the OEM part. The OEM Mercedes-Genuine part has the Mann HU 718/5 part number right next to the Mercedes part number. The only thing missing on this filter is the Mercedes-Benz star logo, Mercedes part number, and the Mercedes-Benz box. Indeed, the filter is made in Germany as well for anyone wondering. Several of the other aftermarket brands actually use the OEM filter rebranded too, as of this writing, K&N oil, and Purolator oil. However, those products tend to be much more costly since those companies must buy the filters from Mann and resell them.
The Mann branded filter is the best value and easiest to procure since it is right here on Amazon! How could it be any easier? I will only say that the OEM dealer Mercedes labeled filter is not too much more money than this one. Therefore, if you ever happen to be at the dealer or know of a dealer that has good parts pricing, you shouldn't necessary run from the genuine filter. It's the same as this and depending on the dealer, might just be a couple dollars more, if you're in a pinch and can't wait.
Overall, extremely recommended filter. You can't argue with the original product! This OEM filter is designed to hold up for the extremely long oil change intervals recommended by Mercedes. Just be sure to use this filter along with an approved oil such as Mobil 1 0w40.

Good, inexpensive filter for Euro cars
Size: Pack of 1
I use these on my BMW, Mercedes, and Volvo cars ('02 and a '99, don't get any ideas) and they work great. Much nicer than the cheap STP / Fram crap at AutoZone or O'Reilly, and not that much more expensive.
The Merc and Volvo share the same filter model, and these come with 2 different sets of o-rings and washers in little baggies labeled "Mercedes" and "Volvo" which I thought was pretty cool.

Nice Filter Wrench for my Volvo V70XC!
Size: 86mm x 16
I was needing a filter wrench for my 2001 Volvo V70XC and couldn't find anything that fit from the local auto parts stores. Not knowing what to expect, I took a chance on this one since most of the reviews were 5 star and the price was exceptional.
When I received it, I was quite pleased with the construction and finish. I have a brand new oil filter housing for my Volvo (since the one currently on my car is chewed up from the former owner using slip-jaw pliers or something on it) and the fit is perfect! I have worked as a mechanic my whole life (aircraft & automotive), and spent a couple of years as a technician at an automotive dealership and I can say that the tool looks like it is designed for heavy-duty use.
The stamped steel housing is thicker than those found in local auto parts stores and the drive adapter has a thick arc welded bead along the inside of the tool. So, it appears to be made to hold up to some fairly heavy torque. Although the product description states that it is 1/2", the drive adapter is actually made for direct attachment to a 3/8" drive. Perhaps this error stems from the fact that they offer a much larger wrench (118-131mm) and this is a more accurate description of their other offerings.
The 3/8" drive adapter works perfectly and a 21mm socket fits nicely on the external hex. Fits with SAE sizes are a mixed bag, though. I was able to attach a 13/16" 12-pt. box-end wrench, but not the opposing open-end. A similarly sized 13/16" 6-pt. socket was extremely tight, so I wouldn't recommend this size and would just go with the 21mm if you had to use the external hex. Otherwise, just use the 3/8" drive adapter for easiest use of this tool. The adapter also incorporates ball detents on all four sides of the internal 3/8" drive, so your ratchet or extension won't easily fall off while in use.
Since this tool is made for oil filter removal & installation, I'm sure that it will deliver as promised. I'll post an update after my next oil change and I get a chance to use it and install the new filter housing I have.
