When checking your oil what color should it be?

• A. Blue
• B. Yellow
• C. Brown
• D. Green

Answer: (B)

Engine oil color reflects its condition. Clean engine oil is usually pale yellow to amber, so seeing yellow on the dipstick suggests the oil is still fresh and in good condition to lubricate the engine. If the oil were very dark brown or black, it would mean it’s old or burnt and should be changed. Green or blue aren’t normal oil colors and can indicate contamination or other issues. So among the options, yellow best matches clean oil.
