I have seen some posts about Sea Foaming your car and how good it is for the car. I wanted to see what others think about this and if I should give it a shot. I have an '03 A6 3.0 with over 150,000 miles on it, well maintained. I am not that mechanically inclined and I don't want to screw up my car. So should I give a shot and Sea Foam my car?

I looked at the steps to do this on-line and the first steps are easy, but the last ones are where I am worried I will screw up the car.

Any thoughts?

 

if guru says its ok....well, its ok.

Seafoam is a great product, but expect some new oil leak after use especially on a high mileage vehicle.

so, they lie..lazy b.

 

Seafoam is too good. It will prolly give you an oil leak from cleaning crud out of some of your gaskets.

 

Good post. I keep looking at Seafoam every time I'm in the auto section of Walmart, but I'm afraid of oil leaks or creating problems by breaking crud loose in the engine. I've changed oil every 8-10k for 160k miles so I thinki I'll stand pat.

Are there similar risks if you just add, say 1/2 a can, to your gasoline?

 

I never had any issues with adding Seafoam to gas and running it through the intake. I normally replace the fuel filter and spark plugs after I do the gas tank and the intake.

 

They are not necessarily being untruthful. Seafoam will not harm gaskets and etc. The issue is that high mileage vehicles have buildup which dries out gaskets. So when the build up is removed, the old gaskets fail. So in reality, they are not lying.

I actually really like Seafoam. I just expect to replace a few gaskets when I do it on a used car. For all the cars that I have owned for awhile, I actually use Seafoam pretty regularly in the crank case. The whole point is to keep gunk from building up so that the gaskets stay pliable.

 

Thanks for the replies. I am just hesitant because like I said I am not that mechanically savy, so if I do this, I am not sure I can replace the gaskets myself. I did replace gaskets years ago on an older car, but it has been a long time.
