الصيغة
Recommended viscosity is determined by a lookup matrix combining climate zone, vehicle age, and driving style.
الأسئلة الشائعة
What does the W in 5W-30 mean?
The W stands for Winter. The number before W (e.g., 5W) indicates cold-start viscosity — lower numbers flow better in cold weather.
Should high-mileage vehicles use thicker oil?
Yes. Engines with over 120,000 km (75,000 miles) benefit from slightly thicker oil (e.g., 10W-40) to compensate for worn seals and increased clearances.
Does driving style affect oil choice?
Sporty or towing driving generates more heat. A higher viscosity grade (e.g., 15W-40 vs 10W-30) provides better protection under these conditions.
