Who uses em? What brand you use? Notice any difference?

In the past I have used Lucas fuel injector cleaner on every 2 to 3 fill ups. Haven't really noticed a huge difference in fuel economy. Maybe about 3 quarters of a mile per gallon more.

So, what is your opinion on Lucas or any other fuel treatments?

 

I used the lucas stuff for about 6000 miles, every fill up, only cause my car had 188000 miles when i bought it. Have not noticed any difference...other than i think my injectors leak. Did not fix that. I think that stuff is snake oil.

 

its made more for keeping good injectors clean and operating. if your injectors are in question its best to have them cleaned and flow tested at a injector shop like this FUEL INJECTOR CONNECTION - Shop Home
