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 recently tried out the Lucas Oil 10003 Fuel Treatment in my car, and I'm happy with the results. I noticed a smoother engine performance and improved fuel efficiency. I use it during long drives, and it has been quite handy. Plus, it's wallet-friendly. Oh, and the freezing temperature in my apartment didn't bother me while pouring it into my tank. Overall, a good buy for maintaining my vehicle's health.

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.
