Engines 2A – Light Duty Suffering Points

Engines 2A – Light Duty Suffering Points explores the most common and costly problems encountered in today’s light-duty gasoline engines. As emission standards tighten and engine designs become more complex, the lubrication challenges have intensified—placing greater demands on engine oils and requiring a deeper understanding of where and why engines fail.

This course focuses on six critical “suffering points” in modern engine operation. You’ll learn the causes, consequences, and lubricant strategies related to issues like oil consumption, cam wear, ring sticking, and turbocharger coking. You’ll also explore the interplay between fuel, oil, and emissions systems—highlighting how oil formulation impacts catalytic converter health and sludge formation.

Whether you work in engine development, fleet maintenance, or oil formulation, this course provides the insight needed to diagnose problems, recommend suitable lubricants, and improve engine durability.

By completing this course, you’ll be able to:

• Identify the most common failure modes in light-duty engines
• Understand how oil consumption occurs and how to minimise it
• Recognise the symptoms and causes of catalyst fouling and turbo coking
• Evaluate varnish, sludge, and wear patterns in engine internals
• Recommend lubricant strategies that address high-risk engine zones
