Frequently Asked Questions

API SP is the latest API Service Category for passenger car motor oils (introduced 2020). It provides enhanced protection against Low Speed Pre-Ignition (LSPI), timing chain wear, and improved high-temperature deposit control versus API SN Plus.

Synthetic oils are chemically engineered base stocks (Group III, IV or V) that outperform mineral oils in extreme temperatures, oxidation resistance, and energy efficiency. Mineral oils (Group I/II) are refined from crude petroleum. Full synthetics typically offer extended drain intervals (10,000–15,000km+) and better protection under severe duty cycles.

Refer to your vehicle or equipment manufacturer's manual for the recommended viscosity grade (e.g., 5W-30, 10W-40, 15W-40). You can also use our Lube Finder & Spec Matcher tool to select the correct product based on your make, model, and operating conditions.
