Paleobiology[ edit ] Both paleobiological and molecular evidence indicate that AM is an ancient symbiosis that originated at least million years ago. AM symbiosis is ubiquitous among land plants, which suggests that mycorrhizas were present in the early ancestors of extant land plants. This positive association with plants may have facilitated the development of land plants.
But when you start talking real performance data from standardized tests, and actual chemical content, the truth comes out fairly quickly. I really did my last oil change when I Sample pest analysis for harley davidson it to AMSOIL at 43, miles, I really do havemiles on it now, and I really can scan and send you the oil sampling analysis report showing that the oil performance is still greatthe oil is very clean, and the engine wear rate is very low.
I can recognize world-class. So this is a way for me to give to people some tangible everyday benefits from my engineering training and research. The best ones are essentially trained by the OEM car-company service techs, to be good at wrenching — efficiently and correctly.
Engineers are the ones who design the cars, and the ones who determine much of the content that goes into the service manuals. Engineers design the manufacturing process equipment. My professional reputation as an engineer is far more important to me than selling some oil, which is why I tell everyone about being a Preferred Customer to buy at wholesale and cut out my retail profits.
Lubrication industry insiders know that AMSOIL products are the worldwide benchmark performance standard, and all the test data and accolades attest to that fact.
And major trucking and construction companies also hold their AMSOIL secrets closely to their chest because of the competitive advantages it gives them.
Marketing is an entirely different subject from performance. Every single one has noted and measured performance improvements, and to my knowledge none has gone back. As far as I can make it, my website is a bullshit-free zone that is data-driven. Call me if you like: But please accept this challenge to be a true skeptic — identify the products for your vehicle, buy them at wholesale as a Preferred Customer and use the products yourself, to prove to yourself whether or not they really work.
Most people are skeptics: Like this semi-truck with amile oil change and engine teardown analysis [archived field testing]. And like the engine teardown report on this Chevy Express expedited delivery van, [test archives] with one million miles on the original engine and transmission.
The big problem is that — are you ready for a shocker? So loading the filter with that large-particle content is going to dramatically skew all the results. But the engine wear-particle range is historically regarded by the SAE as 5 to 25 microns.
The air filter is how most wear particles get into the engine oil. I wonder if this is a deliberate attempt to imply the idea of a driving course, to keep consumers from realizing that while ISO test dust can meet either Coarse or Fine specifications, they are using Coarse dust.
In the link you provided, they noted difficult challenges in accurately testing with Coarse dust — you can imagine the greater technical difficulty and cost in obtaining good resolution and accuracy levels with a Fine dust sample size range. However, there were at least two manufacturers of that DDOF technology.
Again, the graphs would have looked very different with Fine dust, but in the case of oiled gauze and DDOF they will also look different depending on the amount of oil in the filter: Current AMSOIL filtration is nanofiber technology, introduced in late if my memory is rightand is exclusive on the market.
Nanofiber technology dominates performance in hospital operating rooms and electronics clean-rooms, as well as industrial dust-capture and military equipment filtration.
A critical difference is that these nanofiber air filters are surface-loaded filtration. And of course, it eliminates all the issues of under or over-oiling of the filter media.
And you get that performance level from the start — not eventually, after driving the vehicle for 10, miles and getting the dust-cake buildup, which you lose every time you replace a conventional filter with a new one. AMSOIL worked with Southwest to put the test data in the clear, concrete terms of Absolute Efficiency at a specific micron size — which I feel is a big advance in terms of indicating actual wear-prevention performance and briefly stating real numbers that consumers can accurately understand and use for comparison.
Nor does it reveal the inability of conventional filter technologies to stop the smaller wear particles of 10 microns and below, due to the dust-cake which is formed so quickly in coarse media when using Coarse test dust.
In essence, using Coarse test dust is not only the historic norm for testing, but is also a very effective way to hide the performance superiority of nanofiber filtration technology.
Ea is the notation for Absolute Efficiency. One reason AMSOIL refers to their filters in this way is because they rival the performance of the Absolute Efficiency master reference filters that have traditionally been used to capture and analyze the Coarse test-dust particle content that passes through conventional filters.
However, I hope these are some helpful insights in interpreting test data and understanding the filtration technology. Let me know if you have any other questions.

A PESTEL/PESTLE Analysis of Harley-Davidson shows that the company has many opportunities to grow its business and improve its resilience.
However, the PESTEL/PESTLE Analysis also highlights the importance of strategic reform based on external factors in Harley-Davidson. Thank You All – My New Wheelchair Accessible Van – @BennyDiar. 4, CommentsFriday • July 15, • by BENNY DIAR.
Thank you all, for more than I can articulate.. All your contributions, in many different ways, have made getting a new wheelchair accessible Van possible. An arbuscular mycorrhiza (plural mycorrhizae or mycorrhizas, a.k.a.
endomycorrhiza) is a type of mycorrhiza in which the fungus (AM fungi, or AMF) penetrates the cortical cells of the roots of a vascular plant. (Not to be confused with ectomycorrhiza or ericoid mycorrhiza.). Arbuscular mycorrhizas are characterized by the formation of unique structures, arbuscules and vesicles by fungi of the.
