What is the best fuel injector cleaner ?

 

The best I've used is Seafoam. Not only does it clean the injectors but it also cleans the valves, pistons and combustion chambers.

How would I use that SeaFoam to clean my injectors?
Is it a spray? Add it to the gas?
Would this work for a throtle body cleaning?

 

Easiest way is to add it to the gas tank, 1 pint for a full tank.

If' you're loking to clean the throttle body, you'd need to slowly pour 1/3 pint through the PCV valve hose feeding the throttle body. I don't really recommend this unless you're engine is high mileage. Instructions are on the website here:

You can also send injectors out to have them cleaned in a machine if you're that worried.

Me, I'm a bit of a neat freak, so when I do my engine I make sure it comes out spotless INSIDE and out:

 

Luckily, I have access to a machine that cleans the injectors at work. The product we use is by BG Products, it's called 44K.

 

The best method is to take it into a shop and have it done by a pro , 44K was mentioned.

If your looking for a drop in tank type go with Lucas Tune-Up in a bottle. It also has a fuel pump lube in it.

My second choice would be Chevron Techron.

RP also makes one.

Most others are just a mix of kerosine and alcohol.

 

Seafoam ftw

 

They make special throttlebody spray cleaner like carb cleaner but special to not damage the throttlebody.

Seafoam works so good it sometimes cleans motorcycle carburetors so they don't need rebuilding. It cleans as you drive and does wonders. Best thing is it's under 8 bucks a can.

 

$9.99 now locally!

 

$6.99 locally at wallyworld minus my 10% employee discount.

 

Wallyworld gets employee discounts? I might want to be a weekend greeter then as much as I spend there.

 

How many miles is it recommneded to use a in the tank cleaner?

 

You get 10% off everything but food and prescriptions. It comes in handy especially nowadays.

 

I treat one tank every oil change. The mix is one ounce per gallon of fuel and keeps everything clean and running great.

 

It now in the tank and this weekend in the intake.....this is only stuff I have ever seen that works

 

Seafoam products work great. I've also had great luck with 3M products. Both the intank, and the injector cleaing stand show great improvements.

 

My box just rolled over 80k and I think it still runs great. But I've been thinking about something like this lately cuz I've been driving it pretty hard now... the milage is starting to drop slowly.

However, I try to remind myself that it's probably just because it's been hard driving. If I re-adjust my driving habits it might fix itself. I've never used this kind of product on a fuel injected vehicle before, I'm not convinced it would work.


-- tl;dr. I'm a forever skeptic. I don't believe it makes a noticeable difference. Is it really worth it? Will i see a difference?

 

With 80K on your box, a tank full treated with Seafoam will def. help. 1 can treats 16 gallons. Just be sure to run the tank down below 1/4 before filling up again to get the full benefit. It truely does wonders to regain lost performance and mpgs.

 

Used Seafoam in an older ( 1990) mini van it helped, but Seafoam is strong and can loosen up and clean out too much crud making a repair needed even more. And it completetley ruined the intank filter on the fuel pump , dropping that tank was a real PITA.

just be warned.
