Agree. Or just look at the window sticker and use the estimated fuel mileage -- adjusted down by maybe 10% to more closely reflect what one could expect in the real world -- and determine one's fuel costs. If it puts one over budget then look for a car with better gas mileage.

OP another thing to consider is the SXT and RT have longer service intervals when it comes to oil changes (max of 12 months) whereas the SP requires more frequent oil changes (max of 6 months).

Also, you probably will go through more tires (and possibly brakes) with an SP or RT than and SXT.

In terms of fueling cost Slidd's link sums it up quite well...although I wish they would list octane rating instead of just saying regular or premium.

Probably because the actual octane numbers can vary with altitude. Out west in the mountains some regular gas is 85 octane and the mid-grade is 87 so you just follow the grade and you'll be ok. Lowest Premium octane number will still usually be 91.

In some places: Flagstaff comes to mind; 90 octane is the top octane. Octane requirement of an engine drops with an increase in altitude. I don't know the "formula" but with a number of my cars -- all except the Hellcat/JCW -- I have often encountered stations selling just 90 octane in higher elevation locales.

However, I had the opportunity to fill my Porsche 996 Turbo with 93 octane gasoline some place in Wyoming and the engine really perked up even at some elevation above, quite a bit above, sea level.

I drive like a grandma (first 500 miles) in eco mode on my 19’ SP and I’m only averaging 18MPG. But it’s also been all city and side streets, no highway.

When I bought my 15 RT with M6 trans, I was averaging ~17mpg (this is what the instrument cluster reading) 100% city driving. But I was typically shifting from 1-3-5 and then finally 6th if mph was above 45 mph. I was running 93 octane as well.

Buy two cars, get one for fun, and a cheap beater for a DD.
