لاحظت عند استعماله فعلا انخفاض صرف البترول ولكن بعد ان ينتهى المحتوى من الخزان يرجع التحسن الى الاستهلاك مثل الاول مع فرق بسيط لا يذكر

I do quite a lot of stop start driving, the engine rarely gets a proper blow out, plus I use supermarket fuels which tend to be cheaper but have less additives than brands. This additive compensates for the ‘negative’ factors and is resulting in mpg figures of around 7% better than officially published, which is amazing. I think it works.
