I tried a search for this and found no answers. I hear all sorts of things about different fuel injector cleaners out there. First of all, do they work? And second of all, which ones? There's always the $3 STP stuff at the gas station, but I've seen other stuff like the BG 44K stuff that's $15-$20 a can!
If they do work, how often should they be used? Thanks!

 

hey i always use "sea foam" red and white can it is the BEST you can buy i put it in everything if you have a lawnmower/atv ect ect that is not running right put some it it will clean the tank lines carb bowl injectors i sware by it $5.00 a can try it you will like the results and it wont harm your o2 sencer i put it in about every 2 months or so

 

I hear good things on the Chevron-Techron stuff too.

 

Fuel injector cleaner has its merits. All cleaners are pretty much the same with the cleaning agents used. I perfer Lucas fuel treatment and injector cleaner.
Since the gasoline industry is trying to save money, a penny pinching way to do this is to add less cleaning additives to thier fuel.
The multiport injectors sit right over the cylinders. Heat soaking occurs when you drive your vehicle short distances. Heat soaking is when the heat of the engine after it is turned off, transfers to the injector. The heat then burns off the fuel left in the injector. This can cause a residue to be left in the injector. Over time the residue builds up, partialy blocking the injector port.
Injector cleaner removes this build up. I normally add a 5.2 ounce bottle of Lucas treatment and injector cleaner to a full tank every 6K miles or so.

 

The dealer most likely forced injector cleaner directly through the injectors at a concentrated rate. To use this method, the technician connects the injector cleaner and its supply tank directly to the fuel lines at the motor. Any fuel return lines to the car's fuel tank are blocked so the cleaner goes only through the injectors. With this type of cleaning, the concentration of the cleaner is very strong, so injectors are cleaned quickly. It also has the advantage of cleaning some carbon off the backsides of the engine's intake valves. Carbon on the back of the valves soaks up or blocks fuel delivery into the cylinders, and rough idles or hesitations can occur.

 

I use Techron in the motorcycle, at least twice every season. Seem to work!

 

I second the SeaFoam. Great stuff!!!

 

Seafoam.

Pick up truck, 225 Evinrude, Lawnmower. I've used Lucas and all the others. I'll stick to Seafoam.
