does the engine restorer liquid actually work? and does injector cleaner give you better gas mileage?

 

I would stay away from the various engine restoring products....some of them have some compounds that are very corrosive.
Injector cleaners will improve fuel economy and performance if the injectors are dirty; otherwise, they are good for preventative maintenance and lube for the fuel pump.

 

Lucas Fuel Treatment works great. Actually anything lucas makes works great!

 

I agree, Lucas products are very good. really good when you can catch them on sale.
