Sea Foam in Crankcase Before and After Photos.

[Gale Hawkins]

Sea Foam does say not to run with it in the oil for long term. They say you should add it to the crank case a few hundred miles before a scheduled oil change so it dissolves the deposits, then you get them out of there when you drain the old oil.

Actually they do state it is for long term usage. Not sure when I would do that however. If I did in a gas engine I expect I would use 15W-40 oil for starters.

As an after service additive into fresh oil, nearly fresh oil, or oil (used condition) that is NOT ready to be changed (based on mileage since last oil change), put the same amount of Sea Foam Motor Treatment into the crankcase as described above, and then regularly monitor your oil for color and clarity. Set a predetermined schedule for checking the oil condition on a mileage, timed, or event basis (like every time you add fuel, etc.) to determine when an oil service is necessary. Monitoring of the oil for color and clarity will tell you when it is time to do an oil change service. NOTE: Do not exceed 3,000 miles without changing the oil.

that color clarity issue is going to beat up the average person...

Agreed but hopefully an average person does not get his hands on Sea Foam.

With that being said after a lot of Sea Foam searching I have found TWO different diesel truck guys that poured Sea Foam into the intake like they were gas engines and naturally they went into run-away condition. One guy had not posted the tear down results but the other one got lucky and just bent the push rods so he just ordered a new set and got way without a tear down to get back on the road again.

The number that never read the print on the can and did dumb stuff was quite high. One guy poured it into the TB with the engine off and broke a rod because it was hydro locked and the list goes on and on.

Warning: Sea Foam, Motor oil, Spark plugs, Oil filters, etc should be used as instructed by their maker.

Dad was helping a dozer operator working on the place who was trying to replace the injectors so he told the operator how another operator did it a few years before by turning the engine over and blowing them out. Bad mistake. For some reason some how the operator was leaning over the top of the engine when he bumped the starter. The injector just missed the operators head. Dad was more careful with advice after that.

Where in today's world do you find an engine like that pictured? There was a time 50-60 yrs ago something like that was not all that uncommon but for the oils we have today, how is it possible other than not changing the oil all together.

I used to know a guy that I don't think hardly ever changed his oil. He did change it but maybe every few years. Took lots of short trips as well including driving to his mail box at the end of his driveway most days. Once took off on a trip across country without changing his oil. He broke down in the mountains and had to be towed hundreds of miles to a city to get a replacement engine. Smart guy and not short of oil change money. So yeah, i could imagine it.

If you change your oil regularly your engine will not look like that.

Or a clogged oil pump pickup.

I agree. Mechanich in a bottle is no substitute for preventative maintenance.

I am not a big fan of any of these snake oils. If you read on the Sea foam bottle it will cure about anything. It smells like alcohol to me.

I mean the stuff has it's uses. It's number one use for me is usually clearing early season stutters from boats. I'm not going to waste my time q tipping out my carb when I can schuck $12 worth of seafoam in the tank and have fun. If I get a nasty motor I'm not going to tear it down and clean it by hand if a little seafoam can help it. I would reserve snake oil for the transmission rebuilds in a bottle, barrs heater core stop flow, or liquid re-ring.

94BULLITT the Sea Foam cans around here do not claim it will cure anything the best I can read. It is just three products from crude oil that some us find worth the price they charge for the stuff to clean up residue left by other products made from crude oil.

It's a good de-glazer, but not a cure all. I used it in a truck to remove carbon build up from the intake and upper end. It worked well and with a noticeable difference. But pouring into the gas tank did nothing as far as I know.
