Oil change frequency depends on your engine type and the oil you use. As a general rule:
Always check your owner's manual for the manufacturer's recommendation. Modern vehicles with a maintenance reminder system will alert you when it's time — but it's good practice to track it yourself too.
Winter tires should go on when average temperatures consistently drop below 7°C (45°F). The rubber compound in all-season tires hardens in cold weather and loses grip. Winter tires stay pliable and provide significantly better braking and cornering on snow, ice, and cold pavement. Switch back to summer or all-season tires in spring once temperatures consistently stay above 7°C.
Your vehicle relies on several fluids to operate safely. Here are typical service intervals:
Most car batteries last 3–5 years. Watch for these warning signs:

Yes. The core app — oil tracking, fluids, tire swaps, service history, reminders, documents vault, nearby shops, and 15 AI questions per month — is completely free with no account required.
Your vehicle details, documents, service history and AI questions are stored locally on your device using your browser's local storage. Free users' AI questions never leave your phone or browser; for Pro users, questions the built-in guide can't answer are sent with a few vehicle details to xAI for an AI answer, and xAI may use them to improve its models. No account is required. If you subscribe to CarMind Pro or turn on push reminders, we store only what those features need (such as your Stripe subscription ID and checkout email) — see the Privacy Policy.
The free plan supports up to 2 vehicles. To track a different vehicle, mark one as sold first, or upgrade to CarMind Pro ($2.99 CAD/month, cancel anytime) for unlimited vehicles, unlimited questions to the built-in car guide, no ads, and PDF service history export.
CarMind AI is a built-in car guide that runs on your device. It covers maintenance, warning lights and specs (oil types, tire sizes, fluid specs, battery specs), with detailed specs for about 70 popular models from 14 makes and general guidance for other vehicles. Free users get up to 15 questions per month, and their questions aren't sent to any AI provider. CarMind Pro subscribers get unlimited questions, plus AI answers from xAI when the built-in guide can't answer — the question and a few vehicle details (year/make/model, odometer, recent service) are sent to write that answer, and xAI may use them to improve its models. See the Privacy Policy.
