id run any synthetic in a 5w20 version and run it to the specified interval. Wouldn't worry too much about it. I think a good quality filter would be a good idea as well smile

How about using the oil wt Ford says to use. Try M1 0-20 or M1 5-20. Both will perform very well. Why do you use E 85 when that will chop your MPG by 15 to 20%?

yeah that's from timing and some extra air and fuel from the tune and intake. Your oil will be fine in the xw20 weight. Not apples to apples but I run a xxw30 weight in my 600hp diesel. That's also to the rear wheels that are 37" tires. The amount of horsepower doesn't mean you should change your viscosity. my oil temps usually sit a couple degrees under 100 celsius and reports are fine.

Your car is easier on oil than you think. Any name brand syn should do just fine. The best way to check is to do a uoa half way through the oci then one at the end. That's what I like to do. Stick with the same oil and do a uoa every couple changes to get warning of problems. If you want me to name an oil I would pick pp in a 5w20 weight. its a great cheaper full syn oil. I use it regularily in my versa in a 5w30 version. Your only worry should be fuel dilution but a uoa will tell you.

I think Mobil 1 EP 0w20 is the best 0w20 on the market. 70% PAO. 5w20 EP would be good too.

In that case (though using a different weight doesn't automatically invalidate your warranty anyway) go with a M1 or Edge 0w-40...good price and top level protection!
