I have not posted but I actually did additional filter testing, this time at 100C
oil at 5900 rpm through 3rd gear into 4th. Amazing I have not been arrested yet. I had some interesting findings but to cut to the point I found the Royal Purple at 5900 rpm resulted in 3-4psig more
oil pressure!!!!! I was at 56 psig with the Ford racing and motorcraft FL-1A and decided to try the Royal Purple and was blown away. In addition as you may remember the Royal purple filter to 20 micron where the Ford is 25 micron. So in addition to better filtering it has less pressure drop when you need it the most. In the end alot of nothing is nothing though, but the RP did win out on both cold and hot
oil.

The OP has already chosen an FE for his Kirkham.
More importantly, what oil filter do I use for my next oil change?  |
