Sure... the vehicle will never know the difference. You should understand the difference in the two oils though... both numbers refer to the viscosity of the oil. The 5 tells you the oil will maintain at least a viscosity of 5 (thinnest) and a maximum of 20 (thickest) when operated within it's design temperature.
Changing to 5w-30 simply means you are allowing the oil to achieve a viscosity of 30 instead of 20 which is slightly thicker in the heat.
Your engine has a thermostat in it that keeps the engine at a certain temperature, typically 180 or 190 but that depends on the make of the car. All oils will be within their viscosity range when at normal operating temperature. Depending on the climate in which you live, the temperature of the oil can very greatly when the engine is OFF and the oil stabilizes to ambient temperature outside. It is then that the 5w becomes important as the oil thickens as it gets cold. In the extreme heat of the south, you don't want the oil to get too thin either though this is hardly a concern anywhere.
In a new vehicle, I would opt for the best oil available... to me that's Mobil 1. Expensive but then why not try to keep the insides of that engine in good shape? Change the oil at 3k to 5k intervals and you will be fine.
Good luck!

ford wants you to use 5w20 but they will accept 5w30 as an alterante. All waranties will still be covered. But I dont know why you would not want to use the specified oil. Engineers use a lot of time and money to find out what is best for your vehicle and 5w20 is the best for all new fords and hondas.

No. The grade of oil is engineered into the running of the engine. Do NOT use any other grade. Why would you anyway? The 5W30 is heavier or thicker at operating temperature which will result in reduced engine efficiency which will result in greater gas consumption. I worked for Ford for years and I know that an engine failure or damage can cause the company to request fluid samples which would result in the voiding of your warranty.
Just do the few things that you are required to do and you will be fine.

yes you can use the heavier grade, almost all of the manufacturers are changing to the newer grade of 5w-20. It has been tested and if you check out the website bob the oil guy, you will find too much info about oil. The reason for the change is to increase gas mileage and actually help with wear as the thinner viscosity gets between the tighter toleranced parts.

Of course..... no problem what so ever..... of course you'll notice a drop in mpg's.....
Btw, 5w-30 shears down to a 20 weight in 3-4 thousand miles anyway.

Read your warranty. If something goes wrong with the engine, you could find out the hard way that warranties have limitations.
