We currently run Edge in our Toyota Avalon with excellent results, in fact the wear numbers were extremely low on the last analysis. The Edge is very, very, smooth. I was running Pennzoil Ultra in my Corolla for the last two oil changes and have to say it was outstanding as well; very smooth on cold starts and cleaned off the varnish stains from my dipstick. I am now running Pennzoil Platinum as I wanted to try it to compare as well. So far, it too is excellent. I would highly recommend either the PU, Edge, or PP! All are solid choices.
