Wow BG 44K
 

I want to thank all who recommended using BG 44K to clean my fuel systems, this stuff is great and really works! My '99 with 155K on the clock feels as if it has gained 20HP just by adding this cleaner. I was unable to locate any directly so I ordered some from Ebay for about $21 including shipping. I will report back on how it effects the lean codes I receive after a week or so of driving.
Thanks again to all!

Thanks for sharing your thoughts..........look forward to hearing more..

I wonder how this stuff compares with Techron; the Chevron fuel cleaner. Anyone tried both and could report back?

Larueb - what issues are you / were you experiencing?

As a long-time Techron user, I'm curious to see if it really makes a noticeable difference (didn't notice any with Techron). Just bought a can on Amazon ($ 19.95, free shipping) and will give it an unbiased try (and hope I don't fall prey to the placebo effect).

BG44k is amazing. My local BP station sells it among other similar additives by the same company (oil, transmission, etc..) and i put it in every 30,000 miles. Makes a huge difference on cars with a lot of miles. I just use it for preventative maintenance.

44k is strong stuff.

How much difference is felt after using fuel injector cleaning products depends a lot on how dirty the injectors were in the first place :). If the injectors are half-clogged with a terrible pattern then, yes, cleaning them will make a big difference....even if the cleaning itself isn't 100% complete.

And, obviously, if the injectors are already clean then cleaning them again isn't gonna change anything.

FWIW my experience is that most BG products work as advertised.

+1, but given that modern fuels have more than enough injector cleaner in them already, I wonder how they get clogged up. I've never experienced such a thing. Possibly the clogging is symptomatic of a deeper, more serious engine problem that will soon return.

One wonders, yes. I can only assume that the detergents in the gasoline, as good as they are, are less than 100% effective.

But I should avoid the word 'clogged' as I don't think it's acurate in this conversation. My understanding is that injectors are very seldom 'clogged' but, rather, the spray pattern and/or volume is easily disrupted by very small deposits.

I didn't take you literally with the word 'clogged'. Spray pattern or flow abnormalities sounds a little geeky and takes me back to my working days. Ewwwwww. ;)

Once you use BG44K you will understand. It is used and available at most all car dealerships.

Never heard of it before. But as with SeaFoam or Lucas products in which I endorse whole heartedly. I stand by these products.

But another highly endorsed product is great if it truly works and you guys stand behind it.

A senior chemist at a major refiner explained this in relation to his own usage pattern.

He switches brands on his Corvette every 3 months, even though his position makes
him eligible to charge his purchases at his own brand on a company card. That's a
lot of dollars to put where his mouth is.

According to him, the detergents in each brand are different enough that one brand
will clean the detergent buildup left by another brand. By switching back and forth,
they each clean up behind the other.

The 44K aside from being "strong stuff", is again different from the particular detergent
combination of any particular brand.

His $0.02

Interesting hypothesis....

I've long been a Chevron Techron user at every oil & filter change. Perhaps I'll try some BG-44K next time....

Since the 'S' word was mentioned, there's NOTHING in Seafoam that can possibly clean injectors or anything else on a modern engine.

This product, which works well for it's original intended purpose of degumming the tiny carbs on pre-WWII 2 stroke outboards, is a mixture of light oil, naptha and rubbing alcohol. That's it.

If using it makes a person feel good, that's fine but be aware that the $10 bottle contains maybe $1 worth of product. :icon_errrr:

Ouch! Interesting you say that because I started using Seafoam after my buddy with an 88' Mustang GT swore by it and I started using it in my jeep CJ7. And I've been a valued customer ever since not actually looking into the modern engines.

I also used to use Slick 50, Marvel Mystery Oil and Restore. But I don't use those any more.

I'll do a little more research on the Seafoam.

Update - I have driven about 275 miles with the BG 44K in the tank and what an improvement in engine idle and power. On the 2nd day I notice a blue cloud of smoke for a second upon start up but now is gone. I guess this was all the "junk" coming out of the engine from its cleaning power as I never had any smoke before. I will remove the codes tomorrow and check to see if any new codes appear after driving. Prior to the BG 44K I was getting codes for lean bank on both sides.
This may be the best $20 I have spent in a long time!

If you had blue smoke coming out the exhaust upon start up, this would be symptomatic of oil leaking into the combustion chamber while the engine is stopped. This might explain why your engine appears to have benefited from the additive. Be prepared for the symptoms to return in the future.

My wife's Audi A6 throws an occasional misfire on one bank and it has new plugs, coils, and fuel filter. I'm wondering if it is something in the injectors or in the fuel rail on one bank. I thought I'd give BG-44K a try, since it did a nice job in the Jag years ago. I will report back if it helps. If nothing more, it may help me diagnose what is going on (providing things improve)

It's funny you mention Seafoam and 2 stroke outboards. I've used it on and off for years in my cars with no really noticeable results. My old two stroke outboard, though, was acting up this summer - hard to start, flooding, etc. I treated it with Seafoam and it immediately cleared up.
