A different way to think about Premium Gas

Story for reference: So a few weeks ago my wife and I bought a large SUV to replace her tiny little wagon. Since everybody seems to forget how to drive when the roads are frozen, and this will be the first winter with our baby riding in the back seat, we thought it was an appropriate time.

The point of this post: We’ve filled up the tank 4 times so we have a little bit of data, but this massive Abrams tank is getting a little over 17.5mpg. Not terrible considering this pony is 4600lbs. But let’s take a step back and pretend we can get 300 miles per tank (that’s another conversation for another time)... the vehicle came with new tires, which, according to Tire Rack roll 716 times per mile. The OEM tires roll 693 times per mile, meaning I’m actually traveling 3.21% less distance than the odometer reads. So that 300 miles is actually 290.4 miles. Then let’s factor in the extra $0.65/gallon you pay to put the good stuff in the tank. So let’s just for argument’s sake say we put in 16.5 gallons. At $2.60/gallon it’s going to cost me $42.90. For that same $42.90, I could have put in an even 22.000 gallons of regular unleaded gas at $1.95/gallon. That 22 gallons of regular unleaded on a brand new Tahoe for instance where there’s no odometer discrepancy and no premium gas requirement, would have taken me the same 290.4 miles, resulting in 13.20 mpg. That’s marginally better than a Ferrari FF or Lamborghini Aventador.

So next time you’re thinking of buying a car that takes premium gas, prepare yourself for the consequences and remember that you did it to yourself. And that you can kind of afford an exotic Italian car which definitely explains the Murcielago in the background of the picture above at the top
