Fuel injector cleaner: when is best to pour it?

[andylawcc]

it seems logical to pour the FI cleaner when the tank is less than full so that the cleaner can be more concentrated, but is there a point where it get too concentrated that it will do damage?

it says it on the bottle.

 

[andylawcc]

it only says up to 25 gallon tanks.

 

[Scouzer]

and yours is more than 25 gallons?

 

[Siva]

I was always told it could cause damage if you poured it when the tank wasn't full, but I don't know if that's true.

Why do you think you need FI cleaner?

 

[acemcmac]

pour it on an empty... filling it will mix it

 

[alm4rr]

how many miles are on the engine?

 

[FeuerFrei]

Directions say to pour it in before filling tank.
That's what I do when I add Chevron cleaner.

That's what I've been doing for years with the Camry. I bring it to the gas station, pour it in there, then fill it up to mix. :thumbsup:

Aside from keeping your injectors clean, a lot of them can also remove any water that might be in your fuel system.

Ding ding ding.
I cringe when I hear those Auto Zone commericals saying how much better gas milage you'll get by adding FI cleaner.
