The statement 'Oil should be changed every 3,000 miles' is

• A. True
• B. False
• C. Not sure
• D. Depends on vehicle

Answer: (B)

Oil-change intervals aren’t fixed at 3,000 miles. Modern engines and oils have different recommended intervals, and many cars now use oil-life monitors that estimate when the oil actually needs changing. In general, conventional oil may be changed around 5,000 miles, while synthetic oils can extend to 7,500 miles or more; some vehicles even exceed that with manufacturer schedules. Severe driving conditions—lots of short trips, extreme temperatures, heavy towing—can shorten the interval, but you still follow the car’s guidelines. That’s why the statement isn’t a universal rule—follow the vehicle’s manual or oil-life indicator for the correct interval.
