During service information research, what information should be gathered?

• A. Vehicle service history and fluid types
• B. Only current mileage
• C. Only tires' brand
• D. Only engine size

Answer: (A)

Understanding how a vehicle has been cared for is essential when researching service information. The most helpful data are the vehicle’s service history and the fluids that have been used or are recommended. The service history shows what maintenance has been performed, what parts were replaced, and whether any patterns of wear or recurring issues exist, which informs what needs attention next. Knowing fluid types and specifications is crucial because using the correct engine oil, transmission fluid, coolant, and other fluids prevents damage and ensures the vehicle operates as designed. Relying only on current mileage misses past maintenance, and focusing on tires or engine size alone doesn’t provide the full picture of past care or fluid compatibility.
