Most East African vehicle owners never conduct oil analysis. Yet a single KES 3,000–5,000 test can reveal engine health issues 10,000 km before they become catastrophic failures costing KES 100,000+.

What Oil Analysis Tests Actually Measure

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

A complete oil analysis examines oil samples for wear metals, additive depletion, and contamination. Each test metric reveals something about your engine.

Key Test 1: TAN (Total Acid Number)

Key Test 2: Viscosity (Kinematic Viscosity, cSt)

Key Test 3: Particle Count (Wear Metals)

Key Test 4: Water Content

Example 1: Healthy Diesel Truck (10,000 km into 15,000 km interval)

Example 2: Petrol Car with Potential Problem (5,000 km interval)

Example 3: High-Mileage Engine with Wear Issues (12,000 km into interval)

Real Fleet Case Study: 25-Truck Fleet Standardizing Oil

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

Challenge: Fleet using mix of oils; unclear which is best. Cost per liter nearly identical for Shell Rimula R6 vs Total Rubia.

Solution: Conduct oil analysis on 3 trucks with each oil type after 10,000 km.

Results:

Recommendation: Standardize on Shell Rimula R6 for entire fleet. Cost: Same per liter. Benefit: Better engine condition across all trucks, easier inventory management.

Follow-up: Implement quarterly oil analysis on 3–4 trucks randomly to monitor performance. Cost: KES 15,000 quarterly for 4 tests; benefit: Early detection of wear trends worth millions in extended engine life.

Myths vs Facts

❌ Myth: "Oil analysis is expensive and unnecessary; just change oil on schedule."

✅ Fact: Oil analysis costs KES 3,000–5,000 but can identify issues early, prevent catastrophic failures (KES 500,000+), and safely extend intervals (saving KES 50,000+/year).

❌ Myth: "Black oil = high TAN; TAN high = must change oil."

✅ Fact: Black color doesn't correlate to TAN. Laboratory TAN measurement is the actual metric; color is unreliable.

❌ Myth: "One oil analysis test is enough; don't need repeats."

✅ Fact: Trend analysis (multiple tests over time) reveals whether wear is stable or accelerating. Single test provides snapshot only.
