I was at the local parts store (pep boys) and i figured that i'd buy some injector. i asked the clerks about the differant brands and they all said that lucas rocks. well I bought some and used it on an emty tank and filled up. well.... i parked it last night and started it up this morning and a nice white chemical fog billowed out of my muffler! my engine is fine so don't start with the blown engine stuff! the smoke smelled ike my dads 66 mustang (rich with un-burt fuel), i let it idle for a few minutes and fog started to go away. I drove it around for a while and after the temps came up to normal the fog went away. I changed the plugs the wires and the pvc valve as well as the two gaskets on the intake(i wanted to do a tune up anyway). the old plugs looked fine but the pvc valve was shot, it weighed at least an ounce more than the new one. the only reason why my car would have smoked like that is the lucas injector cleaner and the ethynal that the hippies are puttin in the gas. so as a warning to everyone else. "stay away from Lucas Fuel Injector Cleaner." my car doesn't smoke now and runs great. has anyone had this same problem?

 

Yes!!! My car doesn't smoke, and runs great too

 

Dude your post in know way proved that the injector cleaner didn't do it's job(especially with all the other stuff you did to the car after the fact).

 

You're supposed to run the cleaner with a quarter or 8th tank of gas, not a full tank. The more you dilute the stuff, the less effect it has. THat stuff is pretty diluted to begin with. To cause any real problems it'd have to be pretty concentrated.

 

Has anybody ever had ANY good experiences with pour in the tank fuel injector cleaners?

I'm asking because I've never been able to find any evidence that the crap actually does anything meaningful. Anybody out there have any evidence?

 

yea dude, most ppl would say that the fact that you have more smoke coming out the back would claim that the injector is doing its job....and u stated it only smoked on morning startup for a minute or two....some would say thats not even ranked as a problem in the FD problem book ;-)

I run a can of BG44K injector cleaner thru the system once a year. Just pour it in the gas tank with a full tank of gas. It's very strong, so once a year is the most you can use it.

 

I used Lucas the other way stated on the can. Pull the brake boost vaccume hose and pour/suck it in to the system. It gets to the injectors and system very fast. The amount of white smoke that comes out looks like your fogging for mosquiteos! Be sure to let the car get up to running temp first. The car ran a hell of a lot better after.

 

Brake Boost line???? Elaborate please.

The brake booster is the big round cannister that the brake master cylinder is attached to. This was the best picture I could find. Disconnect the vaccume hose the red line is pointing to. If you do it this way you may need to play with the throttle a bit to keep it running. It works great this way and you do not have to wait for it to go through the fuel system.

 

Ive used several brands of injector cleaners on several different cars, and never really felt a difference after. I ran some (cant remember brand) through my FD when I bought it, then a few weeks later, pulled the injectors out and sent them to RC Engineering for flow testing and cleaning. They were all slightly clogged, and their spray patterns were not optimal (dont remember exact percentages), but after the cleaning, they all flowed at 98-100%.

 

IMHO There is only one potential problem with using injector cleaners on our cars.

When you mix it in, and drive around you're only cleaning the primary injectors. The only way to clean the secondary injectors is to reach a certain duty cycle on your injectors that usually exceeded only in either a minimum boost mode (I think the min is about 3lbs of boost) or at RPMs over 6000. Only then the secondary injectors kick in. Than, you need to keep it up there above 40 some percent injector duty before the secondaries drop out.

It is a bit hard to keep the secondaries open for extended amounts of time in street driving.

I presently have a the BG44K in my tank and are driving the p*ss out of the car, just to keep the secondaries open for any lenght of time to allow for the cleaner to do its job. I had more than one close call with the local sheriffs regarding this endeavor.

BTW - injector cleaners do work if applied properly to the injectors.

BG Products 44K is by far the best fuel system cleaner, the only one proven to open a clogged injector. I do as Adam does, one can a year. Never felt a difference because it does it's job if used regularly.

 

By injecting the cleaner through the intake/vacuum ports, all it does is hits the rotor face and burns away. Just like injecting water as a carbon removal tool/maintenance procedure. Doing it that way it does not even come close to the fuel injectors, obviously. It HAS TO BE in the gas to clean the fuel injectors. You want as much cleaner versus as little gas as possible, to concentrate the cleaner.

 

I think all Lucas stuff is overpriced crap. There's a site out there that shows it causes your gear oil to bubble.

 

I've used Redline Injector cleaner in my car now for the past 5 years. Half a bottle each to two consecutive tanks once a year and everything seems to work just fine, however I have no definitive data as to whether it's doing anything at all.

 

My favorite is Chevron injector cleaner with Techron.
Follow the instructions on the bottle.
Our tests show products such as these get nearly all the organic deposits out of the injector.
They flow and spray better.

A single hose on the rail is better, and a two hose recirculating system cleaning is better yet.

An off the car cleaning in a workstation such as an AsNu is the best.

Where can someone purchase this???

 

Thanks Kevin! Pouring something into the brake booster line just goes straight into the combustion chamber. How on earth would it go through the injectors?

 

Most parts stores don't carry it. Some may be able to order it for you. A quick google search turned up several places that sell it. Here is a random link. I don't remember where I ordered mine from, but I think it was around $16 per can.

Excellent point.

 

Exactly! And some people wonder why the keep blowing engines. The less the secondaries come on line, the more chance they can clog over time causing a lean condition.

 

The white smoke did look like i was fogging for bugs. lol I really think that the only way to really clean the injectors is to take them out and clean them one at a time. the in the tank stuff should get the bulk crap out. maybe the fog was doing it's job after all???? the car ran with the lucas stuff in it for about 70 miles. it ran fine during that time. maybe since it sat over night and had a chance to dig in and do it's job that it got some of the major crap out? that bg44k stuff is supposed to be good huh, i'll have to look for it. I'm kinda skeptical about the parts and stuff I put on and in my car and I tend to freak out when my car does something strange, like spreading a chemical fog throughout my apartment complex, but it seems to be running fine now. i'll look into that bg44k stuff. i agree that the only way to clean the fuel system is through the fuel tank, and what's this about putting a full bottle in the tank at 1/4 full???? i would tend to think that would lead to bigger problems than a chemical fog. thanks for the input.
