I've seen their ads everywhere, but I never really paid much attention to it. Does anybody on the .org use their products?

 

I only use their oil filters. I really don't care too much about fuel injection clearners, engine oil treatments..etc. As long you keep up with maintanence of your car, those products are a waste of money. I rather spend the money on tranny flush, coolant flush and fuel filters.

 

I used the fuel injection Cleaner a few days ago and put it in my tank I didn't notice any changes

 

If you use the products as advised (e.g. injection cleaner) you SHOULD NOT notice a difference. This means your fuel system is clean. I use the complete fuel system every 6000 miles or so, and I know a lot of people who do the same. It's called preventative maintenance.

edit: yeah...typing is fun!

 

I tried fuel injector cleaner when starts were getting a little harder than usual- by the time the tank got to 1/4, the starts were back to normal...
