Your odometer shows how far your car has gone. Engine Miles helps you estimate how far its gasoline engine has gone. Built for hybrid and plug-in hybrid (PHEV) drivers, Engine Miles uses the fuel you log and your vehicle's gas-mode fuel economy to estimate engine mileage. Keep your fill-ups in one clear log and follow an oil-change goal based on estimated engine miles. START FREE Track one vehicle, log unlimited manual fill-ups, edit your history, and see your estimated engine-mile total. Log oil changes and follow your next oil-change estimate. GO FURTHER WITH ENGINE MILES PRO Add multiple vehicles, explore fuel use and costs in Insights, and look back with a year recap. For plug-in hybrids, see the estimated gas-versus-electric mileage split. Pro also includes CSV import and export, a full backup, Home Screen and Lock Screen widgets, and notification reminders. Choose a monthly or yearly subscription, or a lifetime purchase, to unlock Pro. No account is required. Your vehicle log stays on your iPhone. Usage sharing helps improve the app and can be turned off in Settings > Privacy. Engine mileage and electric mileage are estimates based on the information you enter. Regular hybrids do not show an electric-mileage split. Follow your vehicle manufacturer's maintenance recommendations; the oil-change estimate is a guide, not maintenance advice. Pro subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel them in your Apple Account settings. Lifetime is a one-time purchase.
