  • Does SeaFoam actually work in a vehicle? The ultimate test---a 30-year old truck with noisy lifters and horrible oil pressure! This engine sounds like a 1990s era diesel! Did this stuff work? The video will provide proof!

    I use Seafoam in all of my vehicles. I add a can to about every five tanks of gas. I have a 2006 Honda Element with 140,000 miles on the clock. The emissions light used to come on quite often. Since I have been using Seafoam the emissions light rarely comes on. And the car runs great! I also use it in my two vintage Buicks and my 2012 Maxima. I get better mileage and smoother idle with every car that gets a can of Seafoam in the tank every so often.

    Is there any point in doing something like this to a lower-milage car, say 30K? If for nothing else than a preventive measure? Just thinking out loud; I'm not in the slightest mechanically inclined.

    Bullshit... I know a old fuller here in NZ who has , either an older Hilux, or some kind of Toyota truck anyway, and I remember a few years ago on a trip I looked at the odo and it said 633,000 km... This was years ago and this is his daily driver. I wouldn't be surprised if it's reaching 900 thousand now. That's almost a million kilometers... Does anyone understand this lol. That's a LOT. And that truck runs fine, is warranted and registered. It's all about whether or not you thrash your car.. if you look after it and drive it with its intended purpous. Road rules, not, let's see how quick off the mark I can be, your car will last a long fucking time. PS, his truck was stock standard.. modifying isn't that old guys type of thing. And his truck is still going hard

    Hi there. Could you give us an update on your seafoam engine. Many stories in YouTube land about how using seafoam or a similar product can make a engine start to leak oil from the gaskets. The removal of such particle build up, or sludge if you will, is what is keeping the old dried up gaskets from leaking and the removal of such from the engine with cleaning agents will actually make a previously clean and dry older engine start to leak.

    Interesting video, In the UK we have a brand called forte and i have had and know people who have had bad times with it. Maybe someone can shed some light on it but in two cases i had used Forte engine cleaner in an old high mileage car and also i found out my friend had done the same not long before i had (different cars), in both cases and i insure proper directions were followed but despite being fine at the time (no knocks or taps) both cars blew their engines after within 100 miles of the engine cleans. I used the same product on my own older car which was much lower mileage and it was fine but fair to say i am very sceptical about the flushes. I just made my mind up that the crap in old engines is what is holding them together lol.

    At least in my experience, the catalytic converter does an excellent job of filtering carbon and soot coming from the engine. You might find the engine dying (from high exhaust back-pressure) if you do this very often - you'll need to get a new catalytic converter

    Gained 10 pounds of oil pressure on my 6.0 Chevy after a can in it. Totally cleaned up the engine after I replaced a quart of oil with a bottle of seafoam

    FYI That Lucas additive can cause your rings to stick in their grooves causing "blow by", the condition where you lose some of your compression because it "blows by" the piston and into the crankcase.
    Gura Lube and Slick 50 are a couple more that really can cause a problem. If they even exist any more!
