However, it is crucial to consult the vehicle's owner manual, as manufacturers specify the exact oil grade to ensure optimal warranty coverage and performance. Furthermore, the choice between conventional, synthetic blend, or full synthetic 10W40 impacts performance.
It is frequently specified for older car models, high-mileage engines, and performance vehicles that operate at higher temperatures and loads. Look for designations such as SN or SP, which ensure the oil meets modern engine protection standards, including improved fuel efficiency and emission system protection.
