Frequently Asked Question
Q: Why is SP more expensive than SN? What’s the real difference?
A : API SP is the latest and highest specification available. It provides better protection against:
Low-Speed Pre-Ignition (LSPI)
Timing chain wear
Engine deposits
Turbocharger stress
High-temperature oxidation
SN is an older specification. While still usable for many vehicles, SP offers improved protection for modern engines.
That’s why SP typically costs more — it uses updated additive technology and delivers stronger overall performance.
Q: Which car should use which oil grade?
A: The correct oil grade should always follow the vehicle manufacturer’s recommendation.
As a supplier, I provide certified viscosity grades like 5W30, 5W20, and 0W20 in API SP and SN specifications. The final decision should be based on the vehicle manual and your professional mechanical judgment.
You are the expert in selecting what fits the car.
Q: How many kilometers can this oil last?
A: Oil change intervals depend on:
Manufacturer recommendation
Driving conditions (city vs highway)
Weather and climate
Engine condition
Many professionals recommend around 5,000 km for optimal engine cleanliness and protection. However, the final decision should follow the vehicle’s service schedule and your professional evaluation.
Q: Can I use 5W30 in European cars?
A: Frankol 5W30 is formulated to meet or exceed international API performance standards and is suitable for many modern gasoline engines, including vehicles operating under European performance requirements — provided the manufacturer recommends 5W30 viscosity.
Always verify the required specification in the vehicle manual before use.
