1. Finish your one-time setup Open ChatGPT and sign in to your own account. Start a new dedicated chat. Paste the copied prompt AND tap Send. Name that chat “My Petrol Helper”. The form does not create or name it for you. Intentionally updating an existing setup? Paste into your existing petrol chat and say which preferences you want to change. The generated prompt tells ChatGPT not to replace existing personal preferences without an explicit update request.
Open ChatGPT The prompt asks ChatGPT to remember stable preferences only if Memory is available and enabled, and to confirm what was saved. This form cannot enable Memory or save anything to your account.
This opens the normal ChatGPT website. It doesn’t create a chat, send your prompt or automatically start Voice. You can open the phone app yourself instead.
2. Activate Voice while parked Open your existing “My Petrol Helper” chat in the ChatGPT phone app and tap Voice. Start and test the audio before driving.
3. Each journey or fuel-price request Reopen the SAME chat. Give your current start, destination, departure time, litres to buy and anything that has changed. No new setup or rescan is needed unless your preferences change.
What to say for each trip “I’m starting at [location], going to [destination], leaving [now or time], and buying about [litres]. Changes since last time: [changes or none]. Using my fuel and discount preferences, check the best fuel stop, including extra driving costs.”
Mention extra stops or route restrictions. Give an intersection or landmark if you prefer. If Voice is already active, you can give your route or current landmark hands-free when safe and permitted. Set up the chat, transfer the prompt and start Voice while parked; this form does not provide a fully hands-free cold start.
Correct or restate preferences when needed. Saved Memory varies by account and context, and a new chat may not inherit your details. Reusing the same petrol chat is the fallback.
