True, if you like changing oil, a 10,000 mile interval might be best, and a Fram Ultra or MicroGreen would be a good choice. The MicroGreen needs to be changed every 10,000 miles, while the Fram Ultra could go 2 10,000 mile intervals. Oil choice could be any full syn you see on the shelf at Walmart for 10,000 miles. ... MicroGreens have a blended glass-cellulose fiber media which is comparable to Fram ToughGaurd or Mobil1 or Wix or Napa Gold oil filters, and they have the nice silicone ADBV instead of nitrile. MicroGreens have the unique extra path thru a small element which should work to clean up the oil further, although possibly not much different than a Fram Ultra does anyway.
