Fuel Economy - Toyota Yaris Forums

Your mpg numbers are improving every tank Marcus. I will be interested to know how does your car perform after switching back to regular gas as far as fuel economy is concerned. I have tried a tank of 91 Octane fuel (Chevron) and also noticed that the motor sounded a little quieter. That could just be due to psychological or other reasons though. I have just switched to Shell 87 and the car does not seem to have become more noisy.
