The oil level on the dipstick should be between which marks?

• A. Full and Low
• B. High and Low
• C. Low and Empty
• D. Mid and Full

Answer: (A)

The oil level should sit between the Low and Full marks on the dipstick. These marks define the safe operating range: below the Low mark means not enough oil to properly lubricate and protect engine parts, risking wear or damage; above the Full mark means overfilling, which can cause foaming, increased pressure, and leaks. Keeping the oil between these two marks ensures adequate lubrication without the problems that come from overfilling. For an accurate reading, check with the engine off on level ground, after the oil has settled, and add small amounts of oil if needed, rechecking until the level lies between Low and Full.
