1 Pack (16 Ounce) Extreme Marine & Rv SF-16 Seafoam Liquid 16 Fl Oz

I bought this product for my motorcycle of which has a wet clutch and it has perfect results with regard cleaning the engine internally as well as the ability to add to the Aspen fuel of which I use because it has no ethanol for the residues to be removed from the carburettors , Excellent Product

A product that works. I bought this to use on my mums car that had an intermittent issue with poor running at tick over and accelerating. We spent a fortune with different garages, including the manufacture garage and none could identify the issue. This product has made a major difference with the issue significantly improving and now almost gone. A have used a few cans, although it improved after the first can, and one more should do it. I have since used it on my own car and friend’s cars.

After hearing mixed reviews about this stuf I was sceptical about its claimed abilities. Nevertheless I decided to pony up and buy some of the magic elixir. I have a Yamaha Thundercat which would struggle to start and would pop and fart whenever I tried. I drained the tank as I thought maybe the fuel had gone bad but it was fine. So I added a small amount of the same fuel back to the tank and added a good glug (probably more than I should) of sea foam. I shook the bike a few times to get the stuff to mix thoroughly and cranked the bike over. I got the same coughs, splutter pops and farts as I usually do but that was obviously the fuel that was left in the carbs. As soon as she fired up properly she ran better, less lumpy but not perfect. I let her warm up and she ran better again. There’s still something not quite right but I swear it’s done SOME good. Each time I start the bike now she just fires without issue. No more pops and farts. My GSXR on the other hand worked well before adding Sea Foam and as the bike had been stood for a while I decided to drain the tank. I added some sea foam to a small amount of fuel and poured it into the tank. This time the bike refused to fire up. It just spun up and gave two massive bangs from the exhaust. I’m sure some neighbours might have though someone was firing a shotgun. Anyway I left it as it seemed like it might be flooded, I tried again the next day and the GSXR fired up and ran smoother (I’ll put the failure to start down to operator error). In my personal opinion this stuff really does help. It’s not going to fix all problems as it’s not made of pixie dust and unicorn sh17, but the bikes are running better. At £17 a can it’s cheap enough to try and could save you needing to take your car or bike or mower into the shop. All levity aside, I’m converted and will definitely use this stuff in the future. +5 stars for function -1 star for price

I use Seaform in our diesel tanks once a year and in my petrol motorcycles it does an excellent job. One of my cars which has 146000+ miles had warning lights up and an oil pressure issue with lack of power after several oil changes and the warning Still there I researched this product and added half a bottle to the almost empty fuel tank. After a few hundred miles the increase in power and the smoothness of the engine was very apparent. I then used it on a classic motorcycle which had a rusting tank cleaned and sticky idle and a drop in revs after 2000 rpm. The carbs had been cleaned so not wishing to pull them off again I added Seaform to the fuel and again after a hour the engine ran like silk and the crap in the carbs was either flushed out or dissolved. Now she ticks over and revs freely. Excellent product. Smoky exhaust did make me panic but that is normal as the Seafoam does its thing

Seafoam is the best. I've used it in multiple petrol engines either for fuel and oil treatment and it works like miracle.

First off, don’t use if your car has a DPF. I made that mistake. I used this product on three different engines, first off a 1.4 HDI which does not have a DPF, second was my Lawmower and finally third a 1.6 HDI which does have a DPF. Now all engines run very smoothly, it does what it says as expected however the DPF in my 1.6 HDI regenerated three times in 300km’s of running with this product so it did accelerate the process for that and unfortunately this can be quite a nuisance. All good otherwise I do recommend it for non DPF Diesels

Super fast delivery Had a look on other platforms this was faster delivery and slightly cheaper I got what I ordered The product worked great could see the smoke And smell the product in the smoke You could see the car kicking out build up on the floor would buy again Easy to use Cleaning power is good Value for money

Great product. Cleans inside engine and fuel system. 👍👍

Excellent work

Wirkte Wunder bei meinem 42 Jahre altem Oldtimer Van. Nachdem die Jahre zuvor das Getriebe überholt , der Vergaser, Zündung, Kaltstart, AGR und vieles mehr für tausende Euro erneuert wurde und kaum Besserung brachten - wurde Anfang des Jahres 1,5 Flaschen Seafoam in den viertelvollen Tank gekippt und dann ca. 200 km gefahren. Das Seafoam scheint die Ventile des originalen ungeöffneten 42 Jahre alten 140.000 Meilen Motor so gut gereinigt und abgedichtet zu haben, dass der Van über die gewohnte Strecke über die Alpen nun 20-30km/h schneller ist (30km/h auf gerader Strecke, 20km/h Berg auf) und trotz der höheren Geschwindigkeit (nur) 19-21 Liter (Autogas) verbrauchte von zuvor 21 bis über 23 Liter. Also weniger Verbrauch und mehr Endgeschwindigkeit (ohne zwangsweise runterzuschalten und die Drehzahl ungesund hoch zu erhöhen). Hätte ich es nicht selbst probiert und genau mit App dokumentiert würde ich es nicht glauben. Ich hatte auch vor dem Ölwechsel ca. 200ml Seafoam in das Motoröl gegeben und bin 250km gefahren, konnte da jedoch keine besondere reinigende Wirkung feststellen. Das Motoröl war so sauber wie immer, vllt. weil es seit Jahren schon mit Ceratec Öl-Zusatz läuft (der auch fühlbar gut funktioniert verschiedenen Motoren) und der Motor deshalb sauber war. Bei neueren Autos konnte ich so eine gravierende Wirkung als Benzinzusatz nicht feststellen - aber vermute, dass es auch hier förderlich ist den Motor langfristig sauberer zu halten. Die Moral von der Geschichte: Wenn man ein schlecht laufendes Auto hat, lieber zuerst die 30€ inkl. Versand in Seafoam investieren, und erst wenn das nicht klappt mit dem Schrauben anfangen..... hätte in meinem Fall tausende Euro gespart. Als Ing. spät was dazu gelernt ;-)

Gewoon niet geleverd. Gelukkig geld terug gekregen van Amazon.

discovered this stuff years ago for treating outboard motors...was hard to get hold of but now is easy through Amazon great for giving any engine a bit of a clean out without pulling it apart

I somewhat recently bought a 1983 Volkswagen Vanagon With the 2,0 litre aircooled engine. I went to clean the ERG valve recently and found that it was clogged all the way with just greasy sooty gunk from the exhaust so im guessing my car has not had much of a cleanout ever and the erg filter is likely rusted out but nonetheless I knew that i could quickly and easily clean it out whereas a new erg filter costs a hundred dollars or more. I bought two bottles of Seafoam Motor treatment because its an add on item and that way i could get the discounted price without adding anything on. For my purposes I found it easiest to pour the seafoam into the hose that attaches to the auxiliary air valve as this was easy to remove and fed right into the junction past the Mass airflow sensor. The brake booster would have been more troublesome despite many people recommending it. I Believe you should just look at all the air hoses leading into the manifold of your car and choose which both won't change the way the engine runs and is easy to pour into which in many cases is the brake booster hose. I warmed up the engine so the auxiliary air valve would not be needed for engine operation, and then I had to cover the majority of the open and exposed end of the hose so the engine would not be choked by too much air, then Its a matter of putting the right amount of Seafoam in so that you don't choke it that way either. At this point you will begin seeing white smoke come out of the exhaust. This is a sign that the seafoam is burning and working properly so continue until you've used nearly a third of the bottle. I actually had trouble killing the engine at the end when you are supposed to pour enough in to kill it so I just shut off the ignition after dumping a lot in at the end. I waited about 10 minutes for it to all soak in and then restarted the engine. I let it run for a little and then began a slow drive around the neighborhood in a low gear to run the engine quickly but not too fast. This created the most smoke by far which is good because that meant it soaked well. Once the smoke stopped or slowed significantly I shut the engine off and checked in the ERG valve hole on the manifold once the engine cooled. I Could not find any more of the greasy black gunk so It worked! The rest was split between going into the fuel and the oil to clean out injectors and galleys and I plan on an oil change soon as a result. Great product does what it says it does and my engine is running much smoother now likely due to a more even mixture in a no longer impacted manifold. I also recommend watching a youtube video on how to do this, it helps to see the things I'm talking about.
