Oil service

When to change engine oil and why not to delay it

Engine oil protects the engine, reduces wear and helps carry heat away. Extending the interval too much can increase wear and future repair costs.

Practical advice

How often to change oil

Follow the manufacturer interval, but cars used mainly for short trips often benefit from a shorter interval. Cold starts and city driving are harder on oil.

What to change with oil

The oil filter is normally changed too. Depending on the car, cabin, air or fuel filters may also be checked or replaced.

Why the correct oil matters

Oil is not just about viscosity. Manufacturer specification matters, especially for modern engines and cars with emissions systems.

What to include in the request

Make, model, year, engine and VIN help. If you do not have them, we can still agree the next step.

What to include in an oil service enquiry

  • oil has not been changed for over a year
  • mostly short city trips
  • unknown oil type
  • service interval is due
  • filters and fluids need checking

What to write before booking

Send the make, model, engine, mileage and the last known oil change date. If the service history is unknown, say that directly. Include the make, model, year, approximate mileage and when the symptom appears. Send any relevant photos or inspection reports by e-mail to autoservice1@seznam.cz; the enquiry form does not accept attachments.

Frequently asked questions

Can I still drive with this issue?

A normal oil change can be booked by request. A red oil pressure warning or engine noise is different and should be checked before further driving.

What should I include in the request?

Send the make, model, engine, mileage and the last known oil change date. If the service history is unknown, say that directly.

When is calling safer?

Call if the red oil warning light is on, the engine sounds unusual or there is a visible oil leak under the car.
