Sea Foam Motor Treatment, SF-16

Excellent work

Good product

Tested in several cars, with either gas or engine oil. Unfortunately, there are no changes for the better, given that the product is very expensive.

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 ;-)

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.

15年くらい10万キロ以上乗ったボルボが、100㎞/hで走るのに回転が上がらずに苦労していました。この製品をガソリン充填ごとに、燃料に半分、オイルに半分混ぜて、3回ほど走ると、エンジンがヒュンヒュンとアクセルを踏むと機敏に反応して、新車並みによく走るようになりました。ものすごくいい製品です。

Questa meraviglia ha fatto miracoli! Devi avere un po' di pratica con la meccanica tuttavia con poca spesa si ha una resa veramente impressionante
