I think it is unnecessary on a newer vehicle, I have"de-carboned" my 95'T-100 a few times buy letting it suck it in through the brake line booster. If it makes you feel better to run it through the gas occasionally I don't think it will hurt. Most gas has enough detergent in it to keep your fuel system clean, not to mention the filters on your truck.

 

Whatever you do, don't try to put seafoam through your engine using the brake booster hose, you'll light your dash up like a christmas tree. Ask me how I know.....I used to do it that way with my 99 Dodge Ram and never had a problem so I figured well hell it should work on the tundra as well, hell no it don't, it just screws around with all the sensors and you end up with all the idiot lights on. Oh, well to those who want the nannies turned off all the time, go a head and do this because it completely disabled the traction control and the ABS system, but I had the Limited Slip Differential on permanently.

Personally I would just use the Chemtool B12 its about $4 a can, rather than $10 a can, and its the same stuff. Seafoam is overpriced and you are just buying the brand name on that can.

 

I use seafoam in everting for preventive maintenance. Todays fuel is JUNK! I use it in my boats, cars, trucks, tractors, ect.

 

I use Seafoam consistently in my motorcycle. The ethanol laden gas we are stuck with gums things up easily and it absorbs water like nobodies business. I usually add about 1/4 can to the tank every 1500 miles on the bike. If I wait too long it runs rough, and the performance drop is very noticeable.

I also use it in all of my small engines (lawnmower, trimmer, snow blower, leaf blower, etc.) as fuel stabilizer. Seems to work very well.

I add a can to my truck gas tank about every 3000 miles or so, same with the wife's SUV.
I would never add it to the oil, just sounds like a recipe for failure.

Can't speak for adding to the intake, last time I did that was on a Dodge Dakota that had issues with carbon in the intake. Worked fine then, but that truck had a lot less sensors than the Tundra.

 

Seafoam

I put SF in the tank twice a year. Redline is supposed to have a better cleaning agent for semi-annual use.

Like others, I run SF regularly 3/4 oz per gallon in all small engine applications. They definitely start with fewer pulls, idle and run. Some call it a waste. Easy test, run a tank of pump premium fuel first, then spike it w/ seafoam.

 

I've never heard of this Sea Foam stuff you speak of. I'll do some reading.

 

Awesome stuff. I add a can to a full tank of gas at every oil change as well as add it to the fuel I use for all my small engines around the house.

 

Seafoam

Sea Foam Sales Company

It's been around since the 1940's. Midwest friends tell me they would throw some in the old 2 stroke boat motors to get them started after a winter. Works as a stabilizer and fuel optimizer (my def) as I've kept 92 octane treated fuel for 2 years w/ no problems for small motors.

Lots of oil and additive reading on 'Bob is the oil guy'

They claim 75% of seafoam is naptha and some of the engineers mix their own version of it. They didn't seem too impressed with seafoam- at least not to pay the 7-9$ per pint.

Toyota dealer recommend a fuel additive twice a year. Otherwise they want me to have the fuel system pressure flushed in the shop every 30k.

 

Someone posted a link about a month back for a recipe to make your own.

 

i've used it for everything haha... mower, boat, vehicles. seems to do a very good job at cleaning up rough idle, etc...

 

I have a motorcycle that sits awhile sometimes without being ridden. I fired it up and it was running like crap even after a few tanks of fresh fuel. Couldn't get it over 50mph and acted like a clogged jet. I put a little Seafoam in it and within 10 miles of riding, it picked right up and ran like a raped ape. Since then I use it for preventive maintenance and as a fuel stabilizer. Lawnmower hasn't had any issue even though it sits without use for long periods of time.

It's not often you can see dramatic results from a product but this stuff does work. I heard about it from a friend who used it on a Suburban he bought that the previous owner couldn't get to pass emissions. One can of Seafoam through the carb and no emission issues. He has been driving that Suburban for the past 5 years with no emission issues or fuel system problems.

I have ran into directly through the carb of an old FJ40 as p.m. but didn't notice any change.

 

Great maintenance product for occasional use. I run it through the vacuum system in my Lexus every 10k miles or so and a can every so often in the gas tank.

There's a reason why Ethanol is frowned upon in Boat motors.

(And look at the ground on most vehicles after a good seafoam session through the intake, you'll notice carbon/soot by the tail pipes exit galore from the seafoam cleaning it out).

seafoam can foul your plugs. I only seafoam my vehicles when I'm about the change the plugs

 

Sea foam an older vehicle that has idle issues, then use a good fuel additive such as Lucas or BG. Ran SF thru my sons 92 when he thought the transmission was going out, changed the burned up copper plugs at the same time as well as the fuel filter. Runs like a new truck with 210k on the little 22RE.

 

Seafoam is good stuff, I use it in all yard equipment and my boat. I've also ran it through my wifes MKX, and my in laws Rav4... it cleans things out. It is used routinely to winterize small motors and boat motors. My honda mower started running with a pulsation, bought some seafoam cleaner and it cleared the motor up just like new. $10 beats a $45 service call to Honda.

 

...or a $450 service call.
