Owner reviews for 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.

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.

È un additivo eccezionale, se la macchina non ti dà problemi puoi andare con la dose, se ti fa fumo o altro buttalo tutto dentro.

Io ogni 15.000km circa aspetto di andare in riserva, butto 1L di additivo e faccio il pieno, mai avuto problemi

Redline SI-1 is highly regarded for its high PEA content for carbon cleaning.

Vw actually sell a fuel additive to fix this exact issue. It cleans the injectors

I really like the LIQUIMOLY stuff.

Try adding a bottle of redex to a full tank and see what happens.

You could always try your own additive in the tank, Redex or similar claims to clean fuel injectors and improve efficiency.

I recently used STP 5 in 1 on my 80k 2011 diesel engine. I have noticed no benefits from using it after adding it to a full tank and emptying it.
