My neighbor gave me a case of BG 44k. He works at a dealership, was given to him by a representative. Anyone had good/bad experiences with this stuff?

 

It is similar to Techron. Not my preference as I prefer Techron, but in the European Marque World, it is popular and preferred over Techron. Funny, because when I purchased my BMW M6, the dealer recommended regular use of Techron.

 

Stuff works. It is a fuel stabilizer/ additive. It improves octane by a few points.had a car that was running lean. Showed positive 12 percent on my long term fuel trim and improved it to 7. Dealerships use it for a reason

 

Hmmm...so you're saying that your fuel trims moved 12% in a POSITIVE direction using a fuel additive? So -5% to +7%??

 

I have used 44k for 30 years. Its a good fuel additive for reducing carbon buildup and cleaning the injectors. I actually saw it fix a older dodge van with a 318 in it. It was skipping at idle due to carbon buildup on the back of the intake valves. 2 tanks of fuel with 44k it was cured.

 

I have used it for carbon buildup and as an injector cleaner. The BG44k works good and I have found it to be more effective than Techron. Amazon sells it, but I can only purchase it locally from a Dodge and Acura service dealership. As mentioned before, that might tell you something.

 

No dog in this hunt.

I've learned a long time ago not to get in the middle of brand loyalty/wars in oil, tires, additives, spark plugs, filters, and myriad other marketed products. Although I've never used it, I've heard from lots of BK44 users, similar endorsements. Not being a chemist myself, if I have a loyalty it would be to Techron, but I have to admit, BC everyone I know and admire uses it and I can't really articulate on the chemical composition or why it would be - better, different, the same or inferior to any other competitor's product.

But for comments like - there is a reason dealers use it - make no mistake, dealers use it because they get free cases of it. The power of marketing is age old. I remember STP. Same thing. They would give cases of the stuff away to the "vantage points" where marketing seeds are planted. It did very well in its day, but doubt anyone would use it today....well, maybe...

One other point, in the comment about moving fuel trims, unless the poster misunderstood what he saw, he described a 5% rich condition moving to a 7% lean condition, and not the way he thought, but here is an example where causal relationships attributed to certain actions don't add up. No disparagement meant, but there was likely some other reason he went 12% lean.

 

I spoke to the service techs at both dealerships and they really felt the product was effective. As far as marketing, there is no advisement or display of BG44K at either dealerships. Also, BG44k is not sold at any of our local auto parts store. Quite the opposite of STP which was a big player in the marketing game.

As far as carbon removal, GM has very effective products, including one product that is injected into the cylinders thru the spark plug holes. Let the car sit for an hour, extract with suction and start it up. White smoke will pour out of the exhaust from the carbon deposits.

 

Please do yourself a favor and understand fuel trims before you question them. I do not endorse brands I endorse facts. I was running 12% positive on long term and saw my fuel trims drop to 7% with one treatment. There is such thing as short term and long term fuel trim. Find out what positive and negative means. Back to the drawing board
