Seafoam & fuel injector cleaners

[cdlamb]

Is it safe to use Seafoam in all fuels & all models of vehicle.
What is the active makeup of these products, and is one better suited than others?

I have recently noticed a engine shudder on my F150 3.5 ecoboost, & first going to try cleaning the 3 Mass airflow sensors with CRC product.

I am considering adding a can of seafoam to the tank when it reaches half under full mark (50-60 liters remaining) & run it down to the low fuel light.

Not sure what the best injector cleaners are, and maybe seafoam might do more harm than good.

lots swear by it and others are totally against it (Scotty Kilmer video)

Forget about Seafoam and get Regane Complete Fuel System Cleaner by Gumout.

Seafoam is a poor cleaner, compared to berryman b-12, or techron.
Seafoam is simply alcohol and a bit of naphtha and a lot of oil.

What year F150? How many miles on truck, how many miles on plugs?

If you’re 1st Gen 3.5EB, you may have condensation in your IC causing the stumble. If it’s 2nd Gen, grab some Redline SI-1 and if you’ve got the 36 gallon tank, dump 2 bottles in it, top it off with 93 or 90 E0 if you’ve got it. Run the truck until the low fuel light comes on, then resume normal operation.

My truck made it to 75k before I changed plugs, and frankly they were perfect and could have stayed in. However, since I drive my truck nearly 20k/year and it’s got an E30 tune, I’m sure all the ethanol helps keep things clean. I’ve done one treatment of Redline SI-1 and one of HPL Fuel System cleaner in 70k and it idles like a kitten. You need PEA in your cleaner, not pale oils or wintergreen smell.

There are a few others but those are the better ones. Seagram & MMO & the like aren’t going to clean anything out but your wallet.

E30 is keeping you clean. I was going to suggest half a tank of E85. That’s my go to and I never have fuel related issues.

I change my plugs every 100,000 kilometers on my 2018 F150. I have removed the hose from the intercooler & find a bit oil oil, but nothing alarming.
I have never changed the boots, but think a CEL would come on if any issues with them.
The CEL only came on once & I needed to replace a Oxygen sensor.

I have about 214,000 kilometers on it with no serious issues to date.

Some treatments aren't available in Canada, Techron for sure is 1 brand we can't get.

I agree. Use Berryman's OP, that stuff works well, imo. Also, when I use it, I put it in the car when I know it' unlikely I'll go through the entire tank before a week or so is out. Gives the cleaner a chance to sit in the fuel system a week or more to do its cleaning.

I came here to agree with and suggest Redline SI-1 ($15 on amazon) and Gumout All-in-one. You could try Berryman B12, it's really cheap at Walmart. Some people have good results with BG 44k but I think it's expensive, and I'm not sure if it has PEA and it's true that you really need that to clean the injectors.

Also agree with adding what ever you go with to a tank of higher octane gas. I would also suggest to check out where Top Tier fuel stations are near you and fill up with them. But you want to double check the website. Some listed don't have the sticker at their pumps (personally, I trust that they are TT even if not labeled, some don't agree with this). In my area, Sunoco is a good example for this.

I use Seafoam in engine, fuel and intake and it has served me well over the years. Restore power and MPG

 

[wlk]

Gumout Multisystem Tune Up and Berryman's B12 is my go to for all my vehicles. Anything w P.E.A. will do if you have issues w availability

 

[slacktide_bitog]

The CRC MAF cleaner is good stuff

 

[addyguy]

If you want Techron in Eastern Canada; go to a Hyundai dealership and buy a bottle of their fuel system cleaner - it is just relabelled Techron, even uses the same bottle.

I recently did an experiment with Seafoam concentrated fuel injection cleaner concentrate.
Fleet managed 2017 Chevy Colorado 3.6 approximately 90k miles that was running very rough. I added two bottles, refilled the gas tank with premium fuel, and proceeded to drive the vehicle for 30 consecutive miles in a lower gear maintaining 3500 to 4000 rpm’s.
Afterwards, the engine performs as it should.

Techron complete is the way to go.
