No, it is not a strict requirement to immediately drive on a motorway after adding a fuel additive, but sustained high-speed driving can help the additive circulate more thoroughly through the fuel system. The primary function of most fuel additives in the UAE market is to clean injectors and intake valves, not to decarbonize the entire engine combustion chamber in one dose. For GCC-spec vehicles like the Toyota Land Cruiser or Nissan Patrol, which are often driven in dusty conditions and at high temperatures, deposits can form in the fuel delivery system. A continuous drive of 30-40 minutes on highways like Sheikh Zayed Road or the Dubai-Abu Dhabi highway allows the engine to reach optimal temperature, helping the additive mix uniformly and clean more effectively. However, according to general maintenance guidelines referenced by RTA Dubai and MOI UAE, regular use of high-quality fuel (such as Special 95 or Super 98) and adherence to scheduled servicing are more critical for engine longevity than relying on additives. The cost-benefit analysis for a typical sedan like a Toyota Camry shows that frequent additive use (e.g., a 60ml bottle for 80 AED every 5,000 km) adds significant annual cost with marginal real-world fuel economy gains in city traffic, making it an optional rather than essential treatment for most daily drivers.
