Injector Cleaner in a Bottle

[gray rider]

Probably a lot of opinions on this, but I haven't posted up in a while and I needed an excuse.

Do you think this stuff works:
Lucas Upper Cylinder Lubricant and Injector Cleaner

I bought the 32oz bottle, I use it because it breaks the bad deposits due to ethanol that might clog the fuel ejectors, and cheaper than 94 gas. Of course I don't have a conclusive scientific fact that it works. But Lucas is a brand that I hear good things about.

I personally never understood what it was lubricating. I don't know if this stuff works or not. I usually run some Techron through my rigs every couple of thousand miles because its cheap and it may help. I do notice better fuel economy every time a run a tank with injector cleaner, not sure what that's all about.

I recently tried the Lubri Moly Jectron injector cleaner. Lubri Moly products have a good reputation. I don't think we'll ever really know if any of these additives make a bit of difference. Actual data is scant. We're all judging it by the seat of pants (literally) and suffer from confirmation bias. Having said all that, I'll run a bottle or two through my truck once or twice a year. Why not?

For a good cleaning, short of removing the injectors, I've used products with a high percentage of PEA, like Berryman's Complete Fuel System Cleaner, Chevron's Techron, CRC Cataclean, BK44, or Redline SI-1. Berryman's (above) also has some MEK, Acetone, and Toluene. I add either to no more than ~8-10 gallons of gas. You need to pay at least $8-10 for anything that's going to work IME.

i have heard good things about the BGK44

 

[bsmart82]

The BG 44k is just techron. There is some info about different fuel system cleaners and what works over at bobistheoilguy.com. I have read that techron or the cleaners that use it like 44k, are the only ones that work. We use BG products at work so I use their intake system cleaner with the pressurized rig they sell to shops and the 44k every oil change.

Can't really see the need for any. I have run Costo fuels in all cars for years, with rare exception. They have 5x the federal standard of fuel cleaner. I have put nearly 60,000 miles on it between the last two tune ups, and plugs did not indicate any problems from running too much cleaner. John

I used a few bottles of that stuff in the 80 only because the bottle was the perfect size to fill with diesel additive for another vehicle. Never noticed any difference.

That lubri moly is good stuff I've had great success with it In my old diesel. As far as cleaning, yea it will but all the cleaner in the world won't unclog the small filters in the injectors or replace the orings. If you don't drive it everyday pull the fuel rail ship it to advance injectors and for $75ish total they will come back looking new with a pre and post flow pattern charts.

I've used a product called "Kreen" and I've got to say, it is a very very powerful solvent. It seems to clear the injectors quite well.

well...here in Sudan we have Liqui Moly....i have an injector on my diesel thats not pumping in fuel..fuel is reaching the injector, which seems to be more than slightly clogged..will give it a try and update...a practical example

 

[elhombre]

I drive a fire truck at work and can tell you that we turned in a request to our shops guys because the diesel exhaust was burning our eyes on scene when it was idling. They said it was dirty injectors. They had us run it down to 1/2 a tank and put Techron in it. 2 bottles of the 20+ gallon size. After a few days and 4 bottles, the exhaust cleaned up back to normal irritation levels. Convinced me. This was before Re-gen or DEF engines. Don't know if that makes a difference. Shouldn't, but now the tuning on "save the Earth from Global Warming" engines has jacked them up so much.......

If you are running diesel, I also highly recommend that you swap over to 100% biodiesel. It has a very high solvent value and will clear the injectors nicely and safely in my experience.

You do need to be careful if you have not run 100% biodiesel before.

1) Do it gradually... biodiesel can be mixed in any ratio with petroleum diesel. I did it over several tankfuls... B10 / B20 / B40 / B60 / B80 / B100 (B means biodiesel and the number is the percentage compared to petroleum diesel as mixed in the tank... so B20 means I put in 20% biodiesel. I have ASTM-certified 100% biodiesel available to me commercially. So I would fill the tank with 80% petroleum diesel and then top-off with 100% biodiesel, thus getting me to B20, etc.)
2) I also purchased several spare fuel filters and swapped them out a couple of times as I worked my way up to B100 (100% biodiesel will clear the fuel tank and all the fuel system, including the supply lines, return lines, injector pump, and injectors. It definitely clogged a number of filters as I transitioned over to B100. The stuff that came out with the fuel filters was black/brown and goopy and it was clogging the filters. I never had an engine starve for fuel, because I would pre-emptively check and swap out the fuel filters before they were completely occluded.) Once you get to B100, you should notice that the vehicle will run noticeably cleaner and smoother. I noticed a big difference. Smoother, less vibration, less noise, and NO soot!!! (that's the most-amazing part) I was just amazed. No soot in the exhaust, no soot in the oil. No soot at all. Of course, when I mixed in petroleum diesel (e.g. when I was away from home and buying from truck stops), then it would start to generate soot again.

I have been running B100 for 10 years now. It's great stuff once you understand a few things:

1) It has a high cleaning or solvent value.
2) It has only about 90% of the energy of petroleum diesel, so your MPG will go down by around 10%.
3) It will degrade rubber fuel lines more quickly than petroleum diesel, so you need to either upgrade any lines you have, or be prepared to swap them out as they get soft (It takes quite a while for the lines to be affected, and most vehicles newer than 1994 have the newer viton-based fuel lines, which last a lot longer when exposed to B100).
4) It will gel up at temperatures below about 40 degrees F. In these cases, I just mix with more petroleum diesel to keep it from gelling.

Advantages:
* WOW. It REALLY cleans the fuel lines and the injectors and injector pumps.
* Engine runs VERY smoothly, less noisy, less vibration, no soot!
* Exhaust actually smells like fried food!
* It actually cleared up what little blow-by I had. I'm not sure how (My theory is that injecting B100 into the combustion chambers over the years dissolved some build up on the cylinder walls and the rings, etc.) but I used to have a little bit of blow by, but when I checked it a couple of years after swapping over to B100, it was GONE. No blow-by at ALL. Now to be fair, I swapped to probably a higher grade of oil than the PO, and I do change it every 3000 miles so the better oil may have cleared things as well, but I was just thrilled that it was gone!
* It's a lot safer fuel. It is actually non-toxic and edible! (Not that I would drink the stuff).

Anyway, thanks for listening to my little speech about biodiesel.

If you have a diesel with clogged injectors, I highly recommend you try B100 for few tanks. I'm pretty sure it would clear it out.

You may need to pull the injector and check the spray pattern. If you want less hassle, you could try Kreen or B100.

I'm pretty sure if you could get the go-ahead to swap the truck over to B100 (as detailed in my previous post above), the irritation level would drop to zero when you are on B100. The exhaust will smell like fried food. Unless you find that irritating as well.

@Muddy1....as i said...in Sudan...we dont even have WD40 here let alone B100 etc

Sorry buddy, I missed that.

No worries bro....we do have people who bring in some quality things...but they get sold sometimes before they reach the airport. ..wd40 being one....and I said liqui moly because I asked a friend to get me some....still not arrived though
