I'm currently using Redline in the engine every 5,000 miles, but had great success with Lucas also, both 20W/50. As far as filters, I have used HD's 5 micron, Mobil 1 extended services & K&N, all seem fine.
Redline Shockproof in the Tranny, as I have found nothing better, changed at 10,000 miles.
I'm finishing up a supply of HD oil I got free in the primary, changed every 5,000 miles, then switching to Redline primary fluid.
