BG Fuel additives

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

Rating 5.0

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

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
