The maximum duration without engine oil servicing is 36 hours. Which of the following best matches this limit?

• A. 24 hours
• B. 36 hours
• C. 48 hours
• D. 60 hours

Answer: (B)

Maintenance intervals define the maximum time allowed between engine oil servicing to keep lubrication effective. If the limit is 36 hours, the value that aligns exactly with that limit is 36 hours. Shorter intervals like 24 hours can occur if service is performed sooner, but they don’t match the maximum limit. Longer intervals such as 48 or 60 hours would exceed the limit and risk inadequate lubrication. So, 36 hours is the correct match.
