Your vehicle's owner manual probably says something like: "Use SAE 5W-40, API SN, ACEA A3/B4 or equivalent." If you're buying oil, you've likely seen these codes and wondered what they mean. Here's the complete decoding guide.

Shopping for Oil: What to Look For

This section gives context and practical guidance so you can act on the recommendations with confidence.

Good Oil Label Should Show:

✅ Brand name (Shell, Total, Mobil, Castrol, etc.)

✅ Viscosity (SAE 5W-40, etc.)

✅ API rating (SN, CJ-4, etc.)

✅ Capacity (1L, 5L, 20L, 200L)

✅ Batch/production date (within last 1 year)

✅ Country of origin

✅ ACEA rating (if applicable)

✅ Approval numbers (MB 229.5, VW 502.00, etc.)

Red Flags (Counterfeit or Poor Quality):

❌ Missing API logo (counterfeit)

❌ Blurry or unclear printing (old/fake)

❌ No batch number visible

❌ Wrong API for your vehicle

❌ Significantly cheaper than market rate (likely fake)

❌ No manufacturer contact info

Bottom Line

This section gives context and practical guidance so you can act on the recommendations with confidence.

When buying oil, ask yourself four questions:

1. What does my manual specify? (Start here)

2. Is it API compliant for my year/model? (Safety check)

3. Is it suitable for Kenya's climate? (Performance)

4. Is it from a trusted, authorized distributor? (Authentication)

These points describe the key tradeoffs and how to use the information for better lubricant choices.

Spend the extra KES 50–100 per litre on quality oil. You'll save KES 500,000–2,000,000 on engine repairs later.
