They claim great benefits, but I have no idea if it is anything of value-Note filter listed is same as for 6cyl gas http://www.microgreenfilter.com/ |

It basically contains a bypass filter element in the same housing as a standard filter. My Mercedes has an element similar to this. Bypass filtration can extend oil change intervals, but you should ALWAYS do oil analysis before going beyond the factory intervals. |

"filtration system allows your vehicle to operate up to 30,000 miles without changing the engine oil" yeah, I think i'll stick to 3000 miles and keep my engine longer than 50000 |

2 micron filtration is not particularly good filtration (although much better than the OE style paper filter). Good bypass filters will go down to 1/2 micron, a centrifuge even smaller. Particulate contamination (i.e. soot) is not the main cause of oil degradation anyway. If they are available cheap enough I would consider buying one, but would certainly not wait 30000 miles to change the oil. |

I've done plenty of reading on by-pass filter setups, they work and are a proven setup. If you haven't looked it up, your standard full flow filter is only rated to ~20 microns at single pass filtration with the higher end ones at ~15. Yes that filter will work, but for 30,000 miles? I highly drought that. Remember you can only cram so much filtering media into a 1 quart filter housing, and there's only soo much crap any given filter can hold before becoming blocked and opening the bypass at which point your oil will start to turn into liquid sandpaper. If you've done the reading you'll know that the majority of your oil doesn't really wear out, but instead becomes acidic and contaminated as it deals with blow by, normal wear, and all its other assorted duties. Most of the particulate is sifted out by the filter down to its rating, and the acid is handled by the total base stock of the oil. With the filter taking the particulate out of your oil down to 15 micron you still have your 0-14 micron bits floating around. at that size there nearly harmless, but (from what I've read) your most abundant damaging micron size to an internal combustion engine is in the 4-7 micron range. The acid however has to eventually be flushed out with the old oil, and replaced with new oil else your engine will be eaten away from the inside out. If you really wanna get into higher oil change intervals (using oil analysis as your determining length factor) your gonna have to do what the big rigs do, and look into something like an AMSOIL BMK21 paired with a 2 quart 2 micron filter, centrifuge, or other type of bypass filter setup. Me if i can find a good spot to mount with easy access i might go for a BMK23 wich lets you relocate your oil filter and have the bypass right next to with without having to put holes in your oil pan. I am sure I've left something out but I'm in a rush to finish and get to work. And as with everything you read on the net that it all with a gran of salt cause this is only repeating what I'v read. |

I can see the need one a big rig, where oil changes cost a lot of money and you cover a lot of miles. I change my oil every 5000 miles and I do it myself. A couple of gallons of Mobile1, RotellaT, or Delvac don't cost much, and neither does a Purolator filter. I figure I'll trade the little booger in before the engine needs a rebuild. |

I ran 10k-12k mile changes in my VW TDI, and after 150k miles (including 30k of homebrew bio that was probably not the best all the time) the engine's compression was within 10 psi across all 4 of the cylinders, and at the TOP of the "new engine" spec range according to VW's own book. That was driving the car like a go-kart, and letting it idle for MANY hours on long trips while I slept. I'd say the engine wear was not-too-existent with the stock filters. I'm running about 10k changes in the KJ now, and the oil seems to be doing just fine as well. When I can run bio, I do up to b100, and the KJ loves it. |

...never change the oil. They just keep adding oil to compensate burned up oil and replacing additives based upon oil analysis for the life of the rebuild which can be 40,000 hours + of operation. Since weight and real estate is not a problem they can add a lot of extra equipment such as centrifuges to clean the oil and essentially have an on site reprocessing facility. I suspect that if a company found a way to make a profit on a small scale device to reprocess engine oil, Northern Tools would sell it. If one had a fleet of trucks it may pay for its self, but with one Jeep CRD, a New Beetle TDI, Antique Tractors, and a lawn mower; the oil reprocessor would have to cost less than $500 to pay off for me. I am tempted to add on a small centrifuge powered by oil pressure so I can muck out the stuff my oil filter does not remove. But when it comes to Oil analysis and going 30,000 miles, I factor in the cost benefit analysis. For now 6,000 mile oil changes with synthetic oil and a good Wix filter do the trick. |

I'm due for an oil change soon, and I'm going to try this filter. I contacted the company to see if there was any special deal I could arrange for my fellow Lost KJ members. I received the following: Quote: Thank you for your interest and enthusiasm in the microGreen oil filter. We'd like to offer you a 10% discount on the microGreen oil filters. Just enter coupon code: GoGreen2009. The coupon code is valid until March 31, 2009. Feel free to pass the coupon code to anyone else looking for a great oil filter.
I'm curious to see how well this works on diesel engine crankcase oil. - Chris |

Hi folks, I also pointed the folks at SOMS at this discussion thread, and received a response back from none other than the CEO of the company: Quote: Chris -
I read the posts on the diesel Jeep Liberty forums from the link you provided. Firstly, thanks for your interest in the microGreen Extended Performance Oil Filter. We also appreciate the on-line conversation that the forum has been engaged in. The forum posts were correct in characterizing our filter as essentially having a by-pass element with the convenience of a spin-on canister. The forum was also correct in understanding the basics of oil degradation. What should be noted is that particulate contamination is an accelerant – the particles consume additives and initiate changes in acidity and viscosity. It is well established that if you keep the oil cleaner, you can significantly slow any other changes to the oil, extending the oil’s useful life. Our filter has been extensively tested and development has also been supported by a shared research agreement with the New York State Energy Research and Development Authority. This testing has confirmed the use of the filter with an oil change at up to 30,000 miles. I do want to emphasize how the filter is used. For a vehicle with a standard 3,000 mile oil change, our filter is changed every 6,000 miles, the oil level topped up, and the oil can be used to 24,000. For a vehicles with a standard oil change at 5,000 miles or higher, the filter is changed every 10,000 miles and the oil can be used to 30,000. This does ensure filtration capacity and oil cleanliness. We hope you do consider using the microGreen filter and to use the coupon code that Jason provided. We do hope that you provide us feedback on how the filter worked for you to decrease costs, increase convenience, and protect the environment. Kind regards, Miles Flamenbaum CEO SOMS Technologies miles (at) somstech.com 877-757-7667 x701 http://www.microgreenfilter.com I'll be ordering two filters today, and will keep everyone posted on my experiences. - Chris |

I was pleasantly surprised to find that shipping was included in the price. I got two filters for $45 shipped. - Chris |

I'm curious how this filter would compare to a remotely mounted Amsoil bypass setup, using a normal full flow filter and a bypass spin-on. At least it gets the filter out of the way of ground-based obstacles.
