and just to make a point, premium is 20 cents more than regular. say you fill up your car once a week. for me (since i fill when the gas light comes on) filling takes about 12 gallons. .20 * 12 = $2.40 $2.40 * 52 weeks = $124.80 saved a year with regular. thats not some small amount, at least not to someone like me.



First off, this isn't a stab directly at you, but moreso an attempt to knock some sense into the people who think they are saving oodles of money.

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.
