I've been using Activ8 Friction reducer for about two years down both holes in my Sportster and 15000 miles later I've had no problems, just smoother running and shifting.

I agree with you 100%, and it goes for all engines, not just air cooled. Thats my opinion anyway...
I havn't messed with synthetics yet,,, I've been using Castrol GTX 20/50 all the way back to when it was called XLR and came in a can. Im 56 years old now, and to this day, I have never had an oil related engine failure. Dennis
