Car Maintenance Calculators and Schedule Tools
Regular maintenance is the key to keeping your car reliable and holding its value. Our maintenance calculators help you plan service schedules, understand wear rates, and get the right quantities of fluids and consumables for your vehicle.
The oil change calculator tracks both mileage and time since your last change, because oil degrades even when the car is not driven. The brake pad life calculator estimates remaining wear based on your driving style and pad thickness, helping you budget for replacements before they become urgent.
Getting the coolant mix right is essential for both frost protection and corrosion prevention. Our coolant mix calculator tells you exactly how much antifreeze to add for your local climate. The timing belt calculator is particularly important as a late belt change can lead to catastrophic engine failure on interference engines.
