Put two cans of BG 44k in a 32 gallon tank of gas and after running it through the truck now runs pretty hard right up to it's speed limiter. I've become a firm believer.
Pros: truck runs pretty hard
Part number: 44K

I know BG products actually do something. I had a buddy with an 04 WRX with 240k miles. He put 44k in every other fill up. When the engine finally blew, we tore it apart and the valves were clean as a whistle, looked brand new.
Pros: valves clean as whistle
Vehicle:
Subaru
Mileage: 386242 km
I ran bg44k through a 2006 6.0l ls engine woth a misfire, (2 bottles now) i has not misfired in 10,000 plus miles since. Best $40 i have spent , i use bg religiously ever since.
Pros: no misfire since
Mileage: 10000 km
Part number: 44K
The only thing I use is a can of BG44k once every couple years
Pros: BG44k once every couple
Just use a can of BG and a tank of Shell 93. Then change oil.
Pros: easy to use
A can of BG44K from Amazon for 30 bucks will do essentially the same thing
Pros: same effect, cheaper
Didn\u2019t even know VW made this, I always grabbed BG 44K and would add every 20K or so.
Vehicle:
Volkswagen
Mileage: 20000 km
BG 44K every three months. I've been using BG for 30 years on BMWs and VWs. Expensive, but it was originally recommended to me by a BMW mechanic friend who has seen the difference in the condition of injectors with and without this additive on many cars.
Pros: recommended by mechanic
Cons: expensive
Vehicle:
BMW
BG is generally good stuff, as is LUBRO/LIQUI MOLY. BG is pushed pretty hard to service stations etc, and people like it since it is flashy and german. it also has a pretty established history because of their BG44K product.
Pros: generally good stuff
Cons: not needed as often
44K is great stuff. Sure, it seems rather expensive, but it works very well and I've used it on many cars for me and my family and friends.
Pros: works very well
Cons: seems rather expensive
