Yes, it is generally safe to store commercially available fuel additives in your car for short periods in the UAE, provided you follow basic storage guidelines. The primary risk is not explosion but the product's degradation due to extreme heat, which can reduce its effectiveness. During the summer, when interior temperatures can exceed 60°C, chemical separation can occur. For instance, storing a bottle of a popular injector cleaner like STP or Wynn's in the glovebox of a Land Cruiser parked in direct sun for weeks is not recommended. For long-term storage, the boot is a slightly better option, though not ideal. Authorities like the UAE Ministry of Energy and Infrastructure advise consumers to purchase automotive chemicals from authorized distributors to avoid counterfeit products that may not meet GSO safety standards. A practical approach is to buy the additive close to when you plan to use it. If you must store it, keep it in its original container, upright, and away from direct sunlight and heat sources like the car's exhaust system.

As a taxi driver in Dubai running a Camry on Special 95, I keep a bottle of injector cleaner in the boot. I buy it, use it within a week or two during my next fuel stop on Sheikh Zayed Road. Never had an issue, but I wouldn't leave it sitting through the summer. The heat here makes everything in the car feel warm, even plastic bottles get soft.

في ورشتنا في الشارقة، ننصح العملاء بعدم ترك مواد إضافة الوقود في السيارة لأكثر من شهر خصوصاً في الصيف. الحرارة العالية يمكن أن تفكك المركبات الكيميائية وتجعلها أقل فعالية. عميل جاء الأسبوع الماضي بسيارة نيسان صني وكان لديه زجاجة في صندوق السيارة لمدة ٤ أشهر، كانت المحتويات قد تغير لونها. نوصي بالشراء من وكيل معتمد مثل أدنوك أو إينوك والاستخدام الفوري.

I used to keep a fuel system cleaner in my Pajero for desert trips, thinking I might need it. After one trip to Liwa, the bottle had swelled up and leaked slightly in the glovebox. Now I just add it right after purchase at the station in Abu Dhabi before heading out. Not worth the mess or the potential waste of product.

Managing a fleet of Tucsons for a delivery company, our policy is clear: no long-term storage of liquid chemicals in vehicles. We bulk-purchase fuel additives and our mechanics add them during scheduled maintenance at the depot. This eliminates any risk of leaks, accidental ingestion, or product damage from the constant 45°C+ exposure our vehicles face in daily Dubai-Sharjah traffic. It's a simple risk mitigation practice.
