Frequently Asked Questions
AI
Yes, petrol and diesel engines have different combustion characteristics and fuel system components. Diesel additives often focus on lubricity and DPF regeneration, while petrol cleaners target carbon deposits on intake valves and injectors. Using the wrong type can be ineffective or potentially harmful.
For routine maintenance, using a fuel system cleaner every 5,000 to 10,000 miles is generally recommended. However, if you notice reduced fuel economy, rough idling, or failed emissions tests, a more intensive cleaning treatment may be necessary to restore performance.
Many modern fuel additives are formulated to be safe for hybrid and eco-friendly engines. Always check the product label for compatibility with hybrid systems. Some brands explicitly state suitability for hybrids, ensuring the chemicals do not interfere with electric motor components or sensitive sensors.
