هل يمكن استخدام إضافة الوقود منتهية الصلاحية (منظف الوقود) في الإمارات؟

No, you should not use an expired fuel additive (fuel cleaner) in the UAE, as it can lose its effectiveness for cleaning vital engine parts like injectors or, in the worst case, separate and cause potential harm. Our work with fleets shows the cost-per-kilometer impact: using a degraded additive like an expired bottle of STP or Wynns in a Toyota Hilux or Nissan Patrol provides minimal cleaning, leading to slightly higher fuel consumption—perhaps dropping from 11.5 km/l to 11.2 km/l on Special 95 over a few tanks. This inefficiency, combined with the typical AED 25-40 cost of the additive itself, results in wasted expenditure. For a personal vehicle like a Toyota Camry driving 25,000 km per year in Dubai-Sharjah traffic, proper maintenance using fresh additives when needed, aligned with the service manual, is a more sound economic decision than gambling with expired products. The key financial risk is paying for a product that no longer performs its core function. The RTA Dubai's vehicle inspection guidelines emphasize the importance of proper engine maintenance for emissions and performance, while the UAE Ministry of Energy and Infrastructure promotes fuel efficiency standards, both principles undermined by using compromised chemicals. An expired additive cannot guarantee the cleaning performance stated on its label. The total cost of ownership (TCO) calculation for a vehicle must factor in the efficacy of all consumables used.

Tried using an old bottle of fuel system cleaner I found in my garage on my 2018 Nissan Patrol. It was past its expiry date by about eight months. I added it before a fill-up of Super 98 on Sheikh Zayed Road. Honestly, I didn't notice any difference in power or smoothness during my usual commute to Abu Dhabi. Felt like I just poured AED 30 down the tank. Won't make that mistake again—now I check dates before buying anything for the car.

In our used car showroom in Sharjah, we see the aftermath. A customer once complained of rough idling in a Kia Sportage they just bought from another dealer. Our mechanic found evidence of a gummy residue in the fuel filter and intake. The owner later admitted using several old fuel additive bottles before selling the car, thinking it would "clean it up" for the sale. That residue likely came from the broken-down, expired additive. It created a problem instead of solving one. We now advise all sellers to avoid using any chemical not recently purchased before an appraisal.

As a taxi driver in Dubai, my Corolla's engine is my livelihood. I use a fuel additive (cleaner) every 10,000 km to help with the stop-start traffic and constant air-con use. I would never use an expired one. The engine runs for 18 hours a day in 45°C heat; I need products that work as promised. A fresh additive helps; an old one is just a risk I can't afford.

For off-road enthusiasts, the advice is even more critical. After a weekend in the Liwa dunes, your Patrol or Land Cruiser's fuel system can have extra sediment. Using a fresh, high-quality cleaner with your next tank of Special 95 is a good practice. However, an expired additive, especially after being stored in a hot garage, might not properly blend with the fuel. In a worst-case scenario, it could contribute to clogging in sensitive parts under the harsh engine load of dune driving. It's not worth the risk for your expensive 4x4.
