To determine what type of oil your car needs, you can use an oil selector tool like the one provided by Pennzoil or Mobil 1. These tools will ask for your cars make, model, and year, and provide recommendations for the type of motor oil and transmission fluid that will provide optimal performance.

If your car has a turbocharger or supercharger, or if you have a high-performance model, the required type of oil is often semi-synthetic or fully synthetic. Its important to follow the manufacturers recommendations for oil type and viscosity to ensure proper engine function and longevity.

In summary, to determine what oil your car needs, you can use an oil selector tool or consult your cars owners manual for the manufacturers recommendations.
