🔍 Key Concepts

• Engine lube oil dipstick markings and what ADD vs FULL actually indicate • Why overfilling a diesel engine crankcase can be harmful • Correct condition for checking oil: engine stopped and oil cold vs running/warm

💭 Think About

• Think about what the manufacturer intends when they provide both an ADD mark and a FULL mark on the dipstick. Is the engine meant to run with the oil somewhere between them, or right at one of them? • Consider what might happen if you fill the crankcase well above the indicated FULL mark. How could that affect oil pressure, foaming, or leakage? • Ask yourself: right before starting the engine from cold, what level would give safe lubrication without risking overfill?

✅ Before You Answer

• Confirm which side of the dipstick scale you should be using when the engine is stopped and oil is cold. • Decide whether normal practice is to aim at the FULL mark, between ADD and FULL, or just above FULL. • Eliminate any options that would obviously lead to overfilling the crankcase beyond the manufacturer’s indicated safe range.
