“I got a case of Royal Purple and put it in my Honda Shadow 1100. Wow!

This is terrific stuff! My low end torque is better. I find that i Don’t downshift as often and I can easily start from a dead stop in second gear without stalling.

I also noticed a slight increase in power, and the bike definitely seems to run smoother and quieter. I notice that I am often in fourth gear when I would normally be in fifth.”

“I used Royal Purple Max-Gear 75W140 in a story that I just completed for 5.0 NUSTANG AND SUPER FORDS. The story is about upgrading the front and rear brakes on a 2002 Mustang. The upgrade requires removing the rear axles so the differential cover had to be removed and cleaned.

…There is a marked, smooth difference between the Royal Purple and whatever gear oil was used by Ford. Very smooth.”
