No, I do not recommend using engine oil that has been stored for 7-8 years in your UAE vehicle. The extreme local conditions accelerate degradation, making the oil's performance and protection highly unreliable. For instance, while a sealed container of full-synthetic 5W-30 might technically have a long shelf life, the 40°C+ summer temperatures in Dubai or Abu Dhabi over several years can break down the additives. The cost of a new oil change (approximately 200-400 AED for many sedans like the Toyota Camry or Nissan Sunny, including filter and labor) is minimal compared to potential engine repair costs. A basic engine overhaul for a common GCC-spec V6 engine can start from 6,000 AED, not accounting for downtime. The RTA Dubai's vehicle maintenance guides emphasize using fresh, manufacturer-recommended fluids to ensure roadworthiness and safety. Similarly, the MOI UAE advises regular and proper maintenance to prevent vehicle failures, which directly relates to fluid integrity. Simply put, the risk of damaging your engine's internal components with compromised, old oil far outweighs the savings on a few hundred dirhams. For a typical vehicle driven 25,000 km per year in the UAE, the annual cost of two premium oil changes is a small fraction of the total cost of ownership (TCO), which is dominated by depreciation and fuel. It's not worth the gamble on a key component like engine lubrication.
