Regular vs Premium Fuel?
Has anyone had the chance to run both 87 and 91/93 to compare the performance difference? Not sure what my dealer put in the car as i still have a half a tank. If it was 87 im wondering how much of a difference 91/93 will be compared to the 87. I know you gain hp but do you also gain torque with the the premium fuel over the regular.

Straight from Fordvehicles.com:
Premium Fuel - 412/390
Regular Fuel - 402/377
Guess it depends on how much power you want to give up for the extra $3 - $4 a tank it would cost to use Premium over regular unleaded

Does anybody know if the v6 is rated 305 with regular or premium? It doesn't say on the mustang home page.

Owners manual says 87 octane is recommended for the V6. So, I am assuming those numbers are good to go with 87 gas. It does has a quick subsection about the 5.0 being able to run on 87 but it may need 91 for best performance.

Im asking this because i was wondering if the dealers put in 87. Once i put in 93 will i feel a big difference in 10hp and 13torque extra?

Because at part throttle you can realize the full potential so it is a waste, IMHO. But if you go to the track, definitely.

An 80 mile daily round trip commute, at least a tank a week, will 10HP really be missed in traffic? I doubt it, and the extra few dollars saved doesn't hurt. The technology is really amazing to have 11:1 compression and still use 87. Kudos to Ford.

A great excuse to drive around more and use up that fuel.
