Red Flow Diesel & Petrol Additive by SV GROUP

I tried the Red Flow Diesel & Petrol Additive mainly to clean the injectors and improve the overall running of the engine. The product is easy to use and can be added directly to the fuel as instructed. After using it, I noticed some improvement in the smoothness of the engine and throttle response, but the difference wasn't dramatic. I also didn't experience any major improvement in mileage that would make me consider it a must-have product. The dual-fuel compatibility is definitely convenient, especially for someone who owns different petrol or diesel vehicles. The packaging and built-in measuring chamber are also practical. Overall, it's an okay product for occasional fuel-system maintenance, but I wouldn't expect any dramatic increase in mileage or performance. At its price, I'd rate it 3 out of 5 stars. Pros: Easy to use, suitable for petrol & diesel, convenient measuring chamber Cons: Results are moderate, mileage improvement isn't very noticeable, somewhat expensive for the results
