I have been puting super gas in mustang recently....am i just wasting my money doing this or is there a big difference between super and regular??

 

We have 3.8l v6's.

Use regular 87 octane, our cars aren't tuned for premium or "super"

 

unless you are tuned for it your car might actually run worse

 

wasting money man, it will do nothing.

 

+1

 

wasting money

 

x1000

 

Ditto, ditto, ditto.

 

What about the 4.0 V6? You use Regular correct? I haven't recieved my books yet but I was pretty sure it was Regular?

 

yup the 4.0's use 87 also

 

Hmm. Im using 93 octane and my car actually runs better. It feels like Im getting all that my sixer is worth, which isnt too much, but I could acutally tell a difference. Or maybe my engine is starting to break in at uhm...120,000 miles. hah.

But yeah. The **** aint cheap.

 

your just wasting your money. The computer doesn't change its configuration by deciding what fuel is in your car. Only if you have a 93 octane tune otherwise like I said you are just wasting your money every time you pull up to the pump

 

What everyone else is saying, no reason to waste more cash.. just go with the reg octane..

 

haha yeah i was wondering about the 3.6 thing.
