In your experience what are the Best Fuel Injector Cleaners on the market? Please share your story and results and which one you think is best.

Gasoline. Fuel system cleaners in my opinion do more harm than good.

I've always filled my vehicles with a high quality fuel, and modern high quality fuels have enough detergents in them to mitigate nasty buildup over time.

We'll see how this fares with direct injected engines though - the two cars in our fleet are now direct injected motors, and from what I understand, the traditional "blow the carbon out of the block by revving it out every now and then" doesn't work the same way with DI motors.

That said, I could be talking out my a**, but I remember reading up on my old MazdaSpeed3 and coming away with that.

You're correct about that. The I take valves don't have fuel passing over them so they tend to have carbon build ip more than most engines.

BG44K.

An occasional dose of this (no more than two cans in a 3000 mile period) has done wonders for whenever my engine starts acting up.

I use Lucas Fuel Injector Cleaner and Upper Cylinder Lubricant 1-2 times per year. It's the only one i've trusted for years. The rest of that garbage on the shelf can sit there. BG44K is great too from what I hear though.

mac, yup I'm waiting for a "new" formulation - designated especially for DIG INJECTORS specifically. (mine Turbo too).Anyone here seen anything out there? And who knows this early in the game if "Snake oil " or not

This. I've used it since 2002 with great results.

Seafoam. Also works as a fuel stabilizer if the car sits, and works wonderfully to blow crud out of old engines when spoon fed through a vacuum port.
