For those of you who like to maintain a stash of maintenance goodies, so that you don't have to go out and buy single part each time you need it, here are a few nice deals from Walmart:

A 6-pack of oil filters PremiumGuard Oil Filters for $50. I installed one of these at my most recent OCI and inspected it closely for quality. The filters are made in S. Korea and look very good, of sturdy construction and quality filter media.

These will work in all GLK250s, as well as E250, GLE300d, ML250, and Sprinters with the 2.1L OM651 engine (not sure what years those were).

I dunno about you, but $50 for 6 oil filters is a huge win in my book, considering the typical cost of things these days. Couple these with deals on great oils such as M1 ESP 0w30 in 5L jugs for $27 or Pennzoil Platinum Euro L 5w30 in 5L jugs for $26 and you've got quite the savings.

Happy motoring!

 

A lot of engineering goes into an oil filter to flow and filter to specific micron level, and filter cold. I use Hengst I believe it’s a synthetic Fleese. I wonder how it tests in comparison to approved brands

 

99% efficiency at 25 microns is pretty good to me. All of the reviews over on BITOG and other places are positive.

Mann Filters at Rock Auto are $8.40, same price for OEM

 

I occasionally buy from Rockauto (seems like 20+ years now) from time to time. Bought front pads and rotors for GLK.

For some items, like batteries and oil filters, I buy at a local parts store. Last GLK oil change, I bought a Mann filter ... with the VA discount , I paid about $8 USD.

Pretty much all local auto parts stores (plus many other retailers) give a discount for retired Vets. And some places offer dedicated parking spaces 👍

 

I've tried RockAuto over the years and it's been hit or miss. But if you find good deals on multipacks of things (like filters) it's convenient to only have to pay (and wait for) shipping once.

And I thought since many of the "trusted" OEM brands had recently moved operations out to China where labor is cheap, you don't always get the quality you're hoping for. It doesn't hurt to have another brand option, and a high-quality one at that.

 

Did they give a flow rate ? The media is different than what I have seen. I’ve had bad luck with other Chinese stuff , knowing how complex the motor is using a brand not well known scares me. You really need an independent test to know.

 

It's not unusual for various manufacturers to go to China for manufacturing. Been happening for many years

Even some of the German manufacturers are there. Mann, for example. And "Premium Guard" has a facility there.

It's all about manufacturing savings ... the big difference is IF THE brand manufacturer has dedicated staff to ensure final product quality. Some don't care - others ensure their products meets quality specifications.

Very odd side note: I was in a well known Texas-owned grocery store, looking at their brand Melatonin (a natural OTC sleep aid) ... I picked up and read the bottle: "manufacturered in China, bottled and packaged in USA".
