MG421-8 microGreen Oil Filter

I can’t believe these are the first filters of their type. There simply amazing. You can deffinetly feel that they use heavier gauge steel on the casing of these filters than an average filter. And the filtering job they do is unbelievable. I put one on at 4K miles, drive for 20 miles and my oil was two shades lighter when I got home. Crazy. I’ll continue to buy these. Their filtering is far superior to anything I’ve seen.

filters are 3 years old so must be old stock. not impressed.

I wanted to say that I was happy at first with the filter,however ever since I have installed it I have had a oil leak coming from the gasket area. I have had to even use a filter wrench to tighten it in a attempt to stop the leaking. When I installed the filter there was no remaining gasket from the old filter and I had cleaned the surface area as well. New oil was used to lube the filter gasket prior to the install as well.Thank-you

It's a oil filter that's kinda pricey and rated of very high quality from the Co. that makes them. I put it on a friends car and everything seems to good so far. Their claims seem to be far fetched as I see it. I've seen a couple of pictures of one after it was cut open and it looks like most of the oil goes a standard type element and a portion goes thru a finer looking piece of felt at the end where the bypass spring is. My own cars and motorcycle get the oil changed way often so I think these will be good for someone that leaves their oil in for longer change intervals then me. But hey what do I know Right? They are not priced so high that I wouldn't recommend trying one or a pair as their website sells em. With all of that being said Merry Christmas to all!!

Because of doubts on the filters claimed 99% efficiency and claimed unbeatable extraordinary filter performance far beyond the capabilities of traditional filters, the filter has now been tested again after SOMS refused since 2013 to prove its assertions with results of carried out tests. In fact the filter does not meet the promised expectations. The filters real efficiency is 99.65% @ 40 microns and 81.78% @ 20 microns (ISO 4548-12 multiple pass) and is thus merely an average filter. With claiming 99% efficiency and without disclose also the rating number, the customer is deliberately misled and deceived. The filter purchaser believe and trust that the filter would capture 99% of all harmful particles. However, it is also true, until 2012 the oil cleanliness performance of all SOMS spin-on filter models was unrivaled. Then SOMS altered the original licensed design because of economic reasons, and the filter performance collapsed since then. The filters full-flow media as well as its micro filter media were evaluated as Absolute Rating 20µm. Usually a 20 micron rated filter makes it impossible to capture large numbers of particles substantially smaller than 20 microns. Consequently a lot of these harmful particles remain in the oil. Undoubtedly roughly the same is happen with the spin-on filters of below listed brands:Bosch: 99.0% @ 20μm, Pennzoil: 97.0% @ 20μm, Purolator: 99.0% @ 20μm, Mobil-1: 99.6% @ 25μm, Royal Purple: 99.0% @ 25μm, WIX: 99.0% @ 25μm. (Source: Providers documents) And for comparing: The efficiency of SOMS Spin-on filter models before 2013 was 99% @ 5µm after 10,000 road miles additional testing and not only after some 45 minutes labor testing at ISO 4548-12 multiple pass.Questions?
