FWIW - only 20ppm of Fe wear occurred during the 5063 to 10276 mile OSI. that means that during those miles your Fe wear rate was only 3.84 ppm / 1000 miles. is this oil still in the car? how much make-up oil has it needed?
also, i just read in another thread that "I've been using the EaO15 in my B4." did you have the EaO in during the AFL run?
This oil is still in the car. Makeup oil prior to the 10K sample was just over 1/2 quart. A bit of that was from the 5K sample.
At 10K, I pulled a sample, installed the bypass filter, and added 1 1/2 quarts to cover the filter, hoses, and the 10K sample.
My plan is to run the oil to 15K, sample and check for a solids reduction with the old technology bypass-filter element (BE90), then spin-on a new-tech bypass filter (EaBP90) and run it another 5K. That will give me a filter comparison of sorts. It won't be an indication of oil life potential, as the bypass install and the later filter change will add just over a quart of fresh oil.
Yes - I'm on my third interval with the EaO filter. Again - not recommended due to the out of spec bypass valve setting. VW wants a 30psi differential; this filter is 7-9psi.
I consider my numbers to be worst case -- I wanted numbers for AFL that proved it was good for a severe 10K interval - so I ran it beyond 14K in an old 'work truck wanna-be' car with high soot and an out of spec oil filter.
