There is a flaw in your logic. In order for this to be a true comparison, you must take into account the MPG drop you'll suffer from. We'll call it .5% as a safe (possibly even low) estimate.

So let's do the math.

We'll say an SVT gets 23 MPG on premium, so 99.5% of that is just shy of 22 MPG on regular.

Now take the 14.5 gallon tank, effectively your losing usefulness of .5% of that. So your 14.5 gallons is getting your the same distance that 13.7 gallons of premium would get you.

Now for the price per distance comparison.

Regular 2.40
Premium 2.60

14.5 * 2.40 = 34.80
13.7 * 2.60 = 35.62

0.82 more to use premium based on a low .5% MPG drop.

Someone would have to be out of their mind to put their engine in possible danger only to save $42.64 a year.



how do you know there will be a drop in MPG? people say that but from what i know (from a previous discussion about this on here) noone has actually tried regular in an SVT and done an exact comparison on the difference. Has anyone done this? Yes i agree that there would be a loss in performance... but that doesnt mean that it will lose fuel economy
