Your engine will detune itself to run with lower octane.
The percentage difference in cost is now very small. Yesterday I bought Premium for $2.79, Mid was $2.69 (lowest octane I'd use). That means that if I get 3.5% better mileage with Premium, I am better off using it. So, with a typical mileage of 25mpg, I only have to bump to 25.9mpg to be making money using premium. Plus, I can have a lot more fun (especially in Winter).
On a yearly basis, let's assume you go 15K miles. Assume I get the SAME mileage with either gas just to compare. At 25 MPG, that's 600 gallons of gas. Total cost for Premium $1674. Total cost for mid range $1614.
Whoa... I save a whopping $60 per year, just $5/month, and have less power (and actually, probably a reduction in mileage). No thanks, I will use Premium.
