    Are there any filters as good as Amsoil EaO?

    The major comonent was the extraordinary filtering capabilities of the Amsoil EaO filter vs. "the rest".. For those of us who indeed understand the long term life extension of incredibly clean engine oil, the use of the EaO is of great value.. When I can use an oil filter which provides cleaner...

    No............ Wish there were but no..... George Morrison, STLE CLS

    Cleaner Oil with EaO Oil Filter?

    If you do an EaO search on this thread, there was some extensive discussion and black and white documentation on the filter's unequalled filtration performance. i.e. the used engine oil in my Sequoia was cleaner (by oil analysis) than the oil out of the bottle!! Yes, the EaO is simply the best...

    Oil Filter Efficiency Study

    Yes, I did test the EaO oil filter under varying pressure conditions: on my Toyota Sequoia used oil analysis/particle count which I published the results on this thread some months ago. The EaO turned in "real world" filtration performance (not laboratory constant flow) to a level of cleanliness...

    Oil Filter Efficiency Study

    So, again, the better filters are of either a microglass/cellulose blend or microglass. The pure microglass elements do not swell up with moisture and by-products of cumbustion. I replace/upgrade industrial stinless "filters?" every week with microglass elements and *significantly* increase...

    Oil Filter Efficiency Study

    And, again, even those filters that do have numbers are for a constant flow particle count test methodology. Since our oil engine oil systems are continuously varying flow rate and pressures, those published beta ratio numbers are really not relevant/meaningful, as I indicated in a previous...

    Moble one extended performance vs Amsoil EAO

    Mobil 1 filters are a microglass/cellulose blend while the Amsoil EaO is a full microglass. A full microglass can provide significantly superior oil filtration AND oil flow compared with a blend filter media. George Morrison, STLE CLS

    Oil Filter Efficiency Study

    My comments are relative to the ISO 4548 multi pass test procedures and their relevance to automotive application. ISO 4548 is multi pass oil flow testbut the test uses a constant flow rate during the test. Unfortunately, no automotive/truck engine oil flows at a constant rate. It would seem to...

    GM4718M

    Again, back to the "time/money" discussion.. There is at least one designer oil company whose president's ego will not allow his company to be lowered to the point of having to do outside testing... He has publicly shared his views many, many times... So, in this wonderful world of bean...

    GM4718M

    It is NOT always about "the Money". Some API and other lube testing/certification is relatively inexpensive, as has been discussed many times on this site, yet some oil companies do not take the time or bother to have their formulations confirmed. And it is understandable as it IS a lot easier...

    Amsoil claims M1 is group IV and GC is Grp III

    And of course I understand why it has not been menitoned, but I posted the results of another independent lab indicating that the same Mobil 1 as was GC'd as Group III was predominantly PAO. George Morrison, STLE CLS

    Mobil Delvac 1300

    The main reason is simply viscosity. Most disel engine oils are 40W and a grade or two higher than is optimal for most automotive gasoline engines.. But, yes, excellent question in that the oils are very high performance oils. George Morrison, STLE CLS

    Mobil Delvac 1300

    I posted on another thread that in October, 2007 a large coal mining company I work with had 41 CAT engines whose engine oil analysis indicated iron wear levels of 10 ppm or less, using Delvac 15W40 engine oil. Quite an achievement considering some of the engines were hard working D11R's doing...

    Where to get the beta ratios for fuel filters

    Most fuel filters are paper elements and thus in the 30 micron range... CAT claims 2 microns for its diesel fuel filters but, again, it is a paper element and no way a 2 micron beta 200. And no, no one quotes beta ratios for fuel filters... Again, as they are all paper elements, it is rather...

    Cheap filters Good UOAs???

    From a lube engineer's perspective, the #1 cause of premature equipment failures is very simply "dirt". The higher level of filtration that can be achieved will extend engine and component life. Period.. As has been shared on this site, the use of a high quality synthetic filter such as the...
