Fuel system cleaning

[captaincorolla]

My lovely shop suggested that for a 'mere' $80 they would do a fuel system cleaning. Isn't that where they just dump a bottle of stuff I could buy at pepboys into my fuel tank, then add $70?

I use seafoam but its not as strong as what the dealer uses according to them. B12 is stronger and cheaper than seafoam so you could try that and see how you like it.

Ask them what exactly they do for $80, my best guess is yes they dump fuel cleaner in the tank (full tank) and they probably clean your intake manifold from all the "gunk and residue", etc, etc..

Just use Lucus.that stuff sells like hot cakes. so i have to say it works.

i had a cleaning done on my acura vigor it involved three bottles one in the oil one in the gas tank and one sprayed in the intake while engine hot and well above idle(special attachement).car is driven afew miles. afterwards an oil change is done.i paid $80,iwas impressed with smoothness and power improvement but did not get better gas mileage.overall it seemed worth it.

Pick up some Redline SI-1 Complete Fuel System Cleaner, I find it works wonders.

seafoam etc whatever wont properly clean injectors. Only way to clean them properly is to reverse flush them using ultrasonic.
What that dealership fuel system cleaning is, is just a ripoff. Modern gasolines themselves have cleaning agents in them to keep the fuel system clean.

^^^ Only way to clean them properly is to reverse flush them using ultrasonic.

The way i clean my injectors is by taking them out one by one, put it in a spare rail i have, block the other holes where the other injectors supposed to go (for max pressure), fill the gas line with cleaner "which ever brand u like", and while pulcing the injectors with wires hooked up to it going to a battery, use compressed air to blow into the gas line "where the injector cleaner fluid is" and see it squirt out the injector.

Its quite effective, you can sumtimes see the spray pattern change while cleaning, depending on how dirty it was.
"if you try to use my method, dont use a foam type cleaner, cuz it doesnt give you a good idea of the injector spray pattern"

Probably. I buy a can of seafoam, put about a quarter of it in the brake booster hose (slowly while someone revs the car), laugh heartily at the old people cussing me for smoking up their neighborhood, then dump the rest of the can in the gas tank when I'm down to about a quarter.

I've never failed to get a smoother running car with silghtly better gas mileage.

That will drive dirt into the pintle hole, when you're supposed to drive it out of there. Not good.
