I was always using the Ford Motorcraft 100% Full Synthetic 5W20 in the Focus, and then in the Mustang...I'm likely going to switch to that in the Escape as well. I would use RP or Amsoil, but there isn't anyone that carries it in stock, in the weight I need around Petawawa/Pembroke. Maybe I can get it in Ottawa once I move there.

I noticed a small, but obvious difference between the regular oil and the synthetic...I got quicker throttle response, more power, and better fuel economy with the syn stuff. Only pitfall I've been told with Synthetic, that once your car has had it in it's engine, you can't switch back to conventional oil, as doing so will cause critical mechanical failures...
