sea foam

[bucketmouth64]

Can I put in a can of sea foam in the oil and run vehicle as normal until next oil change or do I need to treat it like an oil flush product and change oil after 10-15 minutes of engine running.

Half a can in the oil, drive it for 50 to 100 miles and then change the oil. Dump the other half in with the new oil and drive it.

Unless there is a reason than you shouldn't have to add it to the oil. If your trying to clean the engine changing oil more frequently will do a better job.

Does seafoam really work to clean everything out by sucking it into the vaccuum hose by the brake booster and dumping it in the gas tank?

Its a fantastic varnish remover. The varnish is what the carbon sticks to. With a hot engine remove a vacuum hose and pinch of if necessary so that just a little air is allowed through the hole. Slowly pour seafoam into the hose. Fast enough to cause the car to run a little rough but not to fast as to make the engine stall. When you get to about half a can add it fast enough to stall the engine. Let it sit for 10 to 15 minutes. Start it up.

I think seafoam is a good product. I pour a little in every time I put fuel in my antique tractors and I pour it in the fuel of some of my small engines. My only complaint is it has got so expensive.

[Jeremy airjer W]

I'd agree on the price. Seafoam is made entirely of petroleum based products. With the price of oil up I'm sure they had no choice but to raise the price of the product.

And then watch the neighbors stare at you because it will smoke like a banshee until the Seafoam burns off. Keeps the mosquitos away in the summer. It does work as an injector/intake/piston top cleaner.

I'm not a big fan of adding anything to the oil. Seafoam is more volatile than oil and will probably vaporize out of the crankcase after it gets heated up on a long trip anyway. If your engine is that dirty you need to take it apart.

my sea foam rep says add 1/3 to the oil 1/3 through the vac system and the rest in the gas but i like to do half oil half vac and a hole can in the gas its 100% petrolium sp? based so it wont hurt anything, as far as injector cleaner i like the lucus better

1/3 of the can in the gas isn't going to help unless you only have a 1/4 or less. It will get diluted into nothing otherwise.
