20W-50 vs 5W-30 Engine Oil — Which is Better for Pakistan?

20W-50 vs 5W-30: Which Engine Oil for Pakistan?

This is the most debated question at Pakistani workshops. Here's the truth:

20W-50 Mineral Oil

• Cheap (Rs. 1,500–3,000 for 4L)
• Suitable for older engines (pre-2005) with worn seals
• Too thick for modern EFI engines in cold mornings
• Reduces fuel economy by 3–8%

5W-30 Synthetic Oil

• More expensive (Rs. 5,000–8,000 for 4L) but lasts longer
• Ideal for all modern Pakistan cars (2005+)
• Better cold start protection (Islamabad winters, mountain areas)
• Improves fuel economy

Verdict for Pakistan

For any car newer than 2000, use 5W-30 or 10W-30 synthetic. Save 20W-50 for older Hondas and Suzukis from the 1990s.
