Barry - Glad you're doing the Solo tomorrow - good luck. I'm using an Amsoil dual bypass oil filter, which I have used on several cars over the last 8 years. One of the filters is a full flow filter like standard filters, the other is a fine filter which takes out very small (1 micron) particles from the oil. About 10% of the oil flow goes through it, so it takes a number of minutes for all the oil to run through that filter. The lower flow rate through it would not allow it to be the only filter. I've had really good luck with these. I'v mounted the filters in the left air intake area, where brake cooling air goes under the filters, but the filters are exposed sufficiently to be cooled. Oil change intervals with this setup are 1 year or 25,000 miles. At 6 months, one replaces the full flow filter and tops off the oil. I had to make a bracket to mount this setup, but it's not difficult to do if you like that sort of thing. Let me know if you guys want more info on this setup. I'm using Amsoil oil, as well.
