STP Super Concentrated Fuel Injector Cleaner is a favorite among Saudi drivers thanks to its availability and trusted results. The formula uses jet fuel as a base, helping it dissolve carbon buildup, varnish, and gum from fuel injectors and intake valves. It’s compatible with all gasoline engines, including turbocharged and hybrid ones.

This cleaner works best when added to your fuel tank every 6,400 kilometers or with each oil change. The STP solution boosts engine responsiveness, reduces rough idling, and can even improve acceleration. It's also available across Saudi Arabia in spare parts stores and online platforms like Amazon, making it an accessible option for routine maintenance.

Liqui Moly’s Jectron fuel system cleaner stands out due to its German-made precision and strong reviews in Saudi Arabia. It’s designed for deep cleaning, targeting buildup in injectors, pipes, and fuel distributors. What makes it especially useful in the Kingdom is its effectiveness with engines that run in high-heat, dusty conditions.

Jectron not only cleans but also improves combustion efficiency and lowers emissions. It’s safe for catalytic converter systems and ideal for use every 2,000 kilometers. Many drivers in Saudi Arabia report better fuel economy and smoother throttle response after use. It’s a go-to product for those looking to restore performance without mechanical work.

To get the full benefit from any injector cleaner, timing and method matter. In Saudi Arabia’s hot and dusty driving conditions, following a routine can prevent long-term engine issues. The best time to use an injector cleaner is when the fuel tank is nearly empty (around one quarter full). This ensures the cleaner mixes more effectively with the fuel.

Pour the entire bottle into the tank, then fill it up with high-quality fuel (91 or 95 octane). Drive normally until the tank is empty. This process allows the cleaner to run through the entire fuel system, breaking down carbon buildup and cleaning the injectors as you drive. For heavily used or older cars, repeating the process in the next tank can improve results.

For regular maintenance, use cleaners every 5,000 to 10,000 kilometers. High mileage vehicles (over 120,000 kilometers) may need cleaning more often. In Saudi Arabia, where city traffic, high temperatures, and occasional low-quality fuel can cause faster buildup, more frequent use is often recommended. Just be sure not to overuse these products, as too much cleaning fluid can loosen deposits too quickly, risking clogs. Always read the product label and check your car’s manual before use.
