A truck operating on an unpaved road accumulates more dust contamination in 1,000 km than a highway truck does in 5,000 km. Yet both operators might use the same oil change interval — wrong strategy for the dust-heavy truck.

Sources of Oil Contamination

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

Engine oil becomes contaminated through multiple pathways:

1. Dust & Particulate Contamination (most common in East Africa)

2. Fuel Contamination (injection leakage or poor fuel quality)

3. Water Contamination (most damaging long-term)

4. Combustion Byproducts (soot, carbon, acid)

5. Oxidation & Thermal Breakdown (not contamination, but degradation)

Myths vs Facts

❌ Myth: "If you change oil regularly, contamination doesn't matter."

✅ Fact: Contamination accumulates faster than regular oil changes remove it. Prevention (air filter, fuel quality) is as important as regular changes.

❌ Myth: "Dust ingestion is a problem only on unpaved roads."

✅ Fact: Nairobi highways still produce dust. Coastal humidity may cause water contamination. No road environment is truly "clean."

❌ Myth: "A cheaper air filter works just as well as OEM filters."

✅ Fact: Budget filters have less filtration area and allow more dust bypass. Difference: KES 200–300 cost premium saves KES 50,000+ in engine wear.
