Frequently Asked Questions
- Is this oil change estimator free?
- Yes, completely free with no signup and no usage limits.
- Does my data leave my device?
- No. All calculations run in JavaScript inside your browser. Nothing is sent to any server.
- Does it work on mobile?
- Yes. The estimator is mobile-first and works on iPhone Safari and Android Chrome.
- How much oil does my car need?
- This calculator estimates oil quantity as engine size × 1.2 — a common rule of thumb. Your owner's manual lists the exact specification. Most 4-cylinder cars take 4–5 litres; 6-cylinder cars take 5–7 litres.
- Is full synthetic worth the extra cost?
- Full synthetic oil typically lasts 10,000–15,000 km vs 5,000–7,500 km for conventional oil. Over time, the extended change interval often makes synthetic more cost-effective, especially for modern turbocharged engines.
