Regular or Super gas for 3.6 V6
 

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 :shakeno:

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 shit 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.
