does anyone use FI cleaner in their cars? I was in the automotive section yesterdya of walmart and looking at all the different brands they offered. Each varying in price.
who uses them and which brand do u use?
is it actually beneficial to use them in the gas tank or does it do more harm than good?
Only ones that I've used that had any sort of effect are:
-Redline SI-1 (pretty concentrated stuff, a viscous additive - my #1 choice)
-Vavoline Synpower Complete Fuel System cleaner (goes on sale pretty often, a good buy)
-Gumout with Regane (new stuff is much better than previous version of Gumout treatments)
-Lubro Moly Jectron (metal can, used for Euro cars - works pretty well)
-Chevron Techron Concentrate (get the concentrated stuff, they make a cheaper variant that doesn't work nearly as well)
I've had less success with STP and Seafoam treatments. Haven't tried Lucas in the gas tank so I can't say one way or another.
None of them work to a degree you will notice. You should be using high quality fuel, and changing fuel filters ( if you can) regularly. Most fuel companies have several cleaners, Chevron uses techron, in their fuel.
If you think, I stress think, you injectors are dirty, take them out get them professionally cleaned and reinstall. Cleaners over time are mosre expensive than getting injectors cleaned or replaced.
No dyno has ever shown an hp increase with cleaners, and no injector cleaner has shown, via INDEPENDENT testing paid by other than the company, to improve injector flow or clean it.
Go to bobstheoilguy website and research it.
Remember, there are many things to make you think injectors are dirty, such as plugs being old, old plug wires, O2 sensors old and dirty, air cleaner etc etc. These all can make a car seem like its running rougher than normal.
Clean them right, and move on.
I log my gas mileage every tank, and the only tratments that I have found to work are:
Berryman B12 Chemtool in-tank carb / FI cleaner. It's some really strong stuff. Been using it about every other oil change in my cars for years now.
Seafoam through induction system: Run small amount at a time through the brake booster vacuum hose. Similar to what an auto repair shop would charge about $90 to do with a more complicated drip-system. I just cover the opening with my thumb, and drip it slowly into a small funnel attached to the hose. It makes some pretty cloudy looking smoke, but you can definitely tell a difference in not only smoothness, but also a little mpg gain.

My 2 cents haha
I second that, seafoam the car. Use a spray bottle and spray it inside the booster line.
Sucks, a while ago I bought a quart of Lucas fuel system cleaner. After running it through 3 consecutive tanks, I realized that each tank was lower gas mileage than without using it. I don't know if it did anything good for the fuel system, but it actually decreased my mileage. I use it in my generator and stuff like that because I figure it might help the carb, but definitely not in my car anymore...
