I know Ford says to use 87 but will it hurt to use 92? Also, does anyone know if Ford uses synthetic oil in these new mustangs?

Your car will, indeed, run just fine on 87, but if you want to and don't mind the extra cost-go for it.
GOLDENPONY said:Here we go again. I'm sorry but burning high octane fuel will NOT cause any harm-I don't know where this idea came from but it's wrong. That being said, you might not get enough of a gain to justify the extra cost, but it won't hurt anything. I have read in more than one place that the new Spanish Oak computer in our cars will, because of the knock sensor, slightly advance the timing with high octane fuel which is supposed to give maybe 2-3 HP more-certainly not enough to beat your buddy's Z06 but a slight gain. I have experienced something on all 4 of the V-8 Mustangs I have owned and that is the engine idles smoother with premium fuel.
