RP is a decent oil, but ho hum of an add pack for the price. Many have success with starting to clean some of the varnish that contributes to the tick with Penz Ultra in 5w30. It's at the low end of the viscosity for a w30 so it doesn't give up to much to a w20 and still gives enough to quiet the ticking.
