http://v6mustangperformance.com/news/ford-mustang-3-7l-v6-engine-explained/^^^Yes, that's right. And don't forget that the car probably performs a bit better on 93 octane...yea I know, some of you Dudes are about to throw the "BS flag" on that claim of slightly better performance with 93... But this Old Dude believes it is so!
I have been getting per the trip meter 26.8 mpg over the last 7k miles running 87 octane.the ECU has been reprogrammed with adaptive-knock spark control. If the two knock sensors embedded in the cylinder block don’t hear knocking, the ECU will keep advancing the spark until it does.
Just for fun lets say 93 octane nets 2 mpg over 87 octane mpg and average fill-up is 12 gallons. Gas prices from my area. Running 93 costs $7.92 more per fill-up. I can buy an extra 3.7 gallons of 87 with $7.92.
87 $2.15 x 12 = $ 25.80 x 26.8 mpg = 321.6 miles
93 $2.81 x 12 = $ 33.72 x 28.8 mpg = 345.6 miles
87 $2.15 x 15.7 = $ 33.72 x 26.8 mpg = 420 miles
I'll take the extra miles per dollar vs the small bump in performance (5-10 hp). Which most butt dynos won't detect due to calibration differences.:headbonk:
