Follow your vehicle’s schedule
The right interval depends on the engine, model year and manufacturer’s service schedule. Check both the time and mileage limits, including any special-use conditions. If the maintenance history is unknown, review it with a professional rather than treating the current odometer reading as evidence of when the last oil change happened.
Request an itemised quote
Ask for the oil specification and approval, quantity, filter and labour to be listed. Two oils with the same viscosity are not necessarily interchangeable in your engine. Keep the invoice with the date and mileage for the next service. These details affect the price; a generic estimate is not a quote for your car.
Distinguish routine service from an oil-pressure warning
A service reminder does not mean the same thing as an oil-pressure warning. Read the message and consult the manual. If the warning requires stopping, reach a safe place and switch off as directed by the manufacturer. Do not keep driving just to reach the garage. Describe the warning in Daba if vehicle recovery is needed.
Too much oil after topping up
Exceeding the maximum can damage the engine. Check the level using your vehicle manual’s method. The cited Dacia manual says not to start the vehicle when the maximum is exceeded and to contact a brand representative. If you suspect an overfill, arrange a check and correction before driving again.
