It helps to increase 1 MPG and would like to share with those who wants to try it. Thanks

 

I agree that if your engine has significant deposits it can help restore MPG to factory specs, but Seafoam isn't marketed as a MPG enhancer. If your engine has only slight to moderate buildup of deposits, you won't see much of a difference, if any. Also, our engines are generally pretty clean as long the maintenance as been kept up.


No auto manufacturer recommends Seafoam or any other treatments like it, likely because if it is applied incorrectly, there can be a host of problems including O2 sensor failure, catalytic converter failure, and other things. The bottom line is, if you don't know what you're doing, you can have a big expensive headache on your hands.

 

why you post this in honda odyssey form and acura forum? I'm sure snake oil will increase both MPG and horsepower.

 

I tried the seafoam and it worked for me to clean up the intake and exhaust valves, so i shared with everyone who has a honda v6 engine

 

You are fully correct. For those who had poor maintenance like me, i found this help to restore MPG. So I tried the Seafoam as lots others tried and it worked in my case so i shared this if it may help others

 

placebo effect. I could say, when I wash my car I get 5 extra hp and 2 MPG increase.

These kind of products are not needed, just change your oil regularly and use a good quality gasoline.

 

^These kinds of products have their place. And they CAN help MPG and possibly make her feel more peppy. But we're talking negligible results unless the car is really really bad. And if it's that bad, generally speaking, you've got other things to worry about.

But with these clean running Js they are not needed.

 

trying seafoam couple months later the cat get clog bingo 1 mpg = $2.25, 1 cat converter = $1200. Indeed you are saving, well from your saving account that is. I did took apart an engine with 180k miles on the clock that has oil change regularly and ran on fuel as manufacture "recommended". There is no significant build up...

 

seafoam probably won't hurt :

 

Sea foam is not recommended for cleaning vehicles. I will never use that cleaner on any customers car I touch.

 

use seafoam to help keep the cats and O2 sensors clean on my cars every 30K miles. I wouldn't say it gives you 1 whole MPG but it helps keep the car in top shape, an older car running on regular maybe.

Seafoam keeps the cats from clogging with daily driving. Lets be real, any car with an engine will have carbon buildup and the EGR system along with the SH-AWD burning oil isn't helping keep engines clean either.

Seafoam through the intake ports using sip sip method works great. If you do it regularly you'll notice a very small smoke cloud. Seafoamed other cars that have never had a fuel cleaner and a TON of smoke poured out.

 

Seems as though we've been down this road before, but with the ecu controlling the A/F ratio 14.7:1 no matter how "clean" the engine is it will be 14.7 and mileage will remain constant. Even with a 99% clogged air filter the 14.7 ratio will be maintained, fuel mileage will be the same, but performance will certainly suffer.

Cats can just plain wear out, but as far as keeping the cat clean in fear of clogging, the only way that occurs is when there is an engine malfunction. In some cases, an incorrect sealer used in or around the exhaust system can contaminate the O2 sensor and causes an incorrect fuel ratio that results in excessively high exhaust temps.

After posting my thoughts, must also state that I've seen, after using Seafoam, posts of 3 MPG increase, smoother idle, less valve noise, better performance, and even found one article where after one container of Techron was used there was 2 MPG increase in fuel mileage.
Have also seen a drop in fuel mileage after use, one car dropped 36 MPG to 29 MPG, another 22 to 19, 27 to 17, O2 sensors killed, plugs killed, even cat died after use, etc....................

From users it appears it's a crapshoot, so just save your money and time, but I guess some just like to see the smoke.

 

Seafoam helps to increase MPG - Honda Pilot - Honda Pilot Forums

Looks like he's posting also on the Piloteers site too
Advertising I suppose

 

I posted it also on MDX, pilots, TL, and Odyssey forum. I am not associated with SeaFoam company. I posted to all honda J engine forum. I posted a controversial statement about seafoam and see different reactions from people. I would like to see those who tried it and what are their results. How many MPG gain or loss from seafoam. People who haven't tried it and gave their opinions is like telling people how to survive in Mar but they never been there.

 

Sorry, you posted that after using Seafoam there was a 1 MPG increase, nothing about seeking reviews from previous users, but you did get different reactions from people as you desired:

Why would one experiment with a product knowing what the predetermined results will be, zero? Maybe you might want to try some of the 100 other fuel mileage increase gimmicks and post some feedback.
You post test results like this on a Forum, just suck it up and expect controversial replies.

 

Funny, Seafoam is highly recommended over on the 2G TL board. If you guys keep dissing seafoam, some of those 2G guys are come over here and whip some internet ass.....

 

Seafoam is fine and all but will be easily canceled out by the tons of easy and free things you can do to immensely increase MPG:

right foot, reduce idling/un-needed weight, proper maintenance, tire pressure, etc.

I see people driving super fast and weaving around and then they complain about pooor mpg.

Gas Mileage Tips

 

I am fine with the results who people responded. I just wonder how people respond to something new

 

Let me post there and see what their responds?

 

BK44 is the engine cleaner most mechanics use. It is more expensive than Seafoam though. And really, these type of products work best on poorly maintained vehicles. If you take care of your car and use quality Tier 1 gas you probably won't need either product.

 

If done properly it will help cleansing. Who cares about an xtra 1 mi/gl

 

Sea Foam really helped on my old 98 V6 when I owned it. Anyone who owned the first generation J engine knew that there is a design issue with the EGR return port into the intake manifold. It frequently got clogged. So sea foam would melt away the carbon sludge in that port and really opened things up.

By the way, the method you employed is sort of dangerous. You stuck the entire vacuum hose into the whole can which can flood the engine with fluid. That's why your engine kept stalling, that required you to apply gas to keep the engine rev high. You need to slowly let the vacuum suck in which doesn't result in stalls.

 

that's true.

 

Actually I was trying to flood the pistons with seafoam and let it soaked for 10 mins to dissolve some of the carbon inside.

 

That is a method many use with large 2-stroke outboard engines, which are prone to carbon build. Inject most of the can slowly into a running engine, then with the last of the can, flood the engine with so that it stalls with Seafoam in the cylinders, let it soak for awhile, then go blow the carbon out of it with a WOT run. It will smoke like a tire fire for a few minutes

 

the smoke from seafoam is NOT CARBON! and only proves that when you add oils to a heated surface ie: the cat, you get smoke!!

The vac method is about the worst thing Joe Average can do!
Simply add 1 can to 8 gallons gas and drive normally, run a plain tank thru, when its down to half/8 gal throw in the 2nd can of seafoam,
You have completed the cleaning dose procedure
Trips over 30 minutes make the heat that helps seafoam dissolve buildup

E10 gas worsens the situation, even Tier 1 gas needs hundreds of miles to do a cleaning, then used each time to maintain.

For my Honda motorcycle group- 6 cylinders-1500cc 100hp, Seafoam at 1 oz per gal- maintenance dose thru one- 6 gal tankful every few months keeps the pistons shiny

Yes- Gen2TL has found this thread!! we love the stuff, the CL crowd turned us on to it

 

I use Seafoam to clean the injectors also
