Industry Standards & Performance Grade
- API Service Category: API SL. This specifies optimization for older gasoline-powered vehicles (predominantly model years 2004 and older). It provides robust high-temperature deposit control and strict anti-wear protection for classic, high-mileage, or specific light-duty utility engines requiring an SL performance tier.
- All-Weather Stability: Formulated with a winter grade rating of 5W to ensure easy pumpability during cold weather starts, minimizing initial dry friction damage, while maintaining a 30-weight thickness under hot highway driving conditions.
