Frequently Asked Questions
How do I measure my real MPG?
Fill the tank, reset the trip odometer, drive normally, then fill again. Divide miles driven by gallons pumped. Repeat 3-4 tanks for accuracy.
Why is my MPG lower than the sticker?
Sticker estimates come from lab tests. Real-world MPG is typically 10-20% lower due to city driving, traffic, AC use, tire pressure, and driving style.
