I'm doing some math...the Yaris has an 11 gallon tank..."premium" 93 octane gas is usually .20 cents more per gallon than "regular" 87 octane gas...that's $2.20 a tank...

If you get 10% better gas mileage with premium, as some have stated (36mpg with regular, 40mpg with premium, etc), then you will be driving as far on 10 gallons or premium as you would be on 11 gallons of regular...

Stop me if I'm losing anyone...

Gas is now above $3 a gallon around my area. You are saving .80 cents if you see 10% better mileage with premium...

I'm thinking this is along the lines of the placebo effect, you believe your more expensive purchase is going to help you, so it does...

Also, how much do you all drive if an extra $2.20 a tank for premium is breaking your wallet? If you drive 10,000 miles a year at 40 mpg, that is about 23 fillups. That is $50 a YEAR...

Sorry for the ramble...but if you believe that premium is helping you, buy it. Scientifically, there is no benefit to running premium in these cars...
