5W20 oil may help as well.
Anything to decrease weight and air turbulence will help with fuel economy. Also if tuning becomes available, a good tune will net you a bit more mileage as well.
Not sure if an intake and exhaust will help at all.

I like the idea of using a lighter oil (5W20) but will that void the warranty? And if using lighter oil, will that provide the required protection?
