    Particle Count Data Point: P1 vs EaO

    Another particle count data point. I ran a Pure One filter for 4000 miles. I pulled an oil sample, then changed to an EaO filter without adding any new oil. I ran the EaO for 549 more miles and pulled the second sample. IMPORTANT NOTE: IT LOOKS AS IF THE EaO SAMPLE MAY HAVE BEEN MISTAKENLY...

    Comparing Particle Count of PP vs. P1 question

    I am running a Premium Plus oil filter. I plan to draw a sample for a particle count at about 4500 miles. I then plan to replace filter with new Pure One filter without changing oil, run for a short time and pull another sample for a comparative PC. I want to see if the P1 cleans up the oil to...

    Particle Count Reproducibility

    I'm planning to compare several oil filters using VOA as a baseline. Besides the many variables that can skew any meaningful results, I'm concerned about: 1. Accuracy of particle counts that accompany oil analysis. 2. Variability of particle content of virgin oil. Does anyone know how reliable...

    Crude Relative Viscosity vs. Temp Tests

    Here are results from some very crude relative viscosity tests of several engine oils at four different temperatures: 108F (heated), 68F (room temp), 41F (refrigerator temp), and -1F (freezer temp). Comparative oil flow was observed and is listed in the order of greatest flow (lowest viscosity)...

    New Pure 1 info, also PP & Maxlife

    I called the Purolator filter hotline a few days ago (12/2005) and found they have new test data for the Pure One Oil filter verses when I called them about six months ago (6/2005). I did not ask why there is a change (new test method or new filter design). Multi pass efficiency test (SAE...

    Ecore AC vs Valuecraft vs Old AC w/pics

    From what I can tell, the new Ecore version of the AC Delco PF53 ($4) is identical to the Valucraft V3614 ($2). The new Ecore filter media is different from the old AC Delco PF53 media, in form, thickness, and number of pleats. Pleat depth is about the same. These three filters were disassembled...

    Filter Comparison Question

    Does anyone know how current this test info is? http://www.smartcar-owner.co.uk/oil_filter.htm It raises some questions, such as: Is the Champion filter the same as USA Mobil 1? Is the Purolator a Pure One or Premium Plus? Who manufactured the Motorcraft? Any thoughts?

    Ecore media differences?

    Has anyone noticed if all of the new ecore filters have the same exact type of media? (AC Delco vs. STP vs. Supertec vs. Valuecraft)
