Before we comment we should know about technology, the product works absolutely. Can you guys answer me that why Honda Civic is coming with an ECON button, why Honda Civic needs an ECON button, why not inbuilt. It is because Honda makes engines not the ECU, they have done the power management to result the fuel efficiency.
How a Mobile oil in an EFI car can save fuel, simple it improves the performance as if the engine gets lighter, same way Panther empowers the ECU and ECU enables to improve the pick up of vehicle and save fuel. There are too many customers now and we should know something before we write.
Cigarette lighter socket is actually a Power socket, the whole car is an electronic design, the Power socket used for Lighter is also one of the power socket. The products works. If people don't believe should keep their self to CNG and should limit their driving experience. If you have not tried the product, you cannot comment on the product because Technology is not perception dependent, its performance dependent. People using it in Civic's, Altis, Range Rovers, Bmw's, Merecedes are not fool and ask them how do they feel, they never try without it.
Best of Luck and Have a Good Day.
Please if some body does a good work, it should be appreciated without having a proper knowledge it is recommend not to spoil whole spirit of it.
