Seafoam Question

I have been doing some maintenance to my truck since i have hit the 120K mile mark. i cleaned the throttle body, new spark plugs, new air filter, changed the oil and tranny fluid. however i have just learned about using seafoam. i was planning on putting it in my gas tank and in though my brake booster. however, i have read that some people say to change your oil after but i dont want to change it since i changed it last week. so is it necessary to change the oil after adding it through the brake booster and gas tank, NOT adding any to the oil.

 

I would do it. I would also put the old plugs back in for the brake booster treatment as they can get a little fouled. You don't want to mess up your new plugs.

 

well i dont have the old plugs anymore so can i just add it to the gas tank and not have to change the oil and plugs? i think i could benifit from the seafoam because my throttle body was pretty dirty so im assuming my engine is pretty bad also because i use to do a lot of work in the mud on the farm with it and ran it pretty hard but i changed the oil last week and put $7/each plugs in the week before and dont really want to replace all that already but as i said i dont have the old plugs

 

Yeah I would just do the gas then because you will most likely mess up your plugs otherwise.

Im personally scared to run it through the intake because its breaking off pieces of carbon that have to somehow make it through the exhaust valves, scary. Im almost at 163k miles and I don't feel like it needs to be seafoamed.

 

yeah for now i may just stick with adding it to the gas tank to be safe and see if that even does anything. im sure it needs to be done but my truck runs pretty good for 120K miles

 

Your plugs will be fine. You wont harm anything doing it through the brake booster.

 

How does everyone feel about running it in a truck with a supercharger? I haven't done it so I thought I'd ask before I did

 

What makes some say i will need to change the oil and it could foul my plugs and others say that nothing will need to be done if I run it through the brake booster? I don't want to start s@#t, just want to figure this out. The seafoam website says that you do not have to change the oil and it doesn't mention anything about the plugs

 

well you should probably trust that other guy more since I have no experience with the stuff. I was just kinda going off common sense but I could be completely wrong.

 

"....its breaking off pieces of carbon that have to somehow make it through the exhaust valves...."

I agree with this about the carbon break off. Everywhere I read I get mixed opinions. I can see having to change the oil if u put it in the oil but I wasn't going to do that.

 

I called the seafoam company and they told me i will not need to change the oil after using it through the brake booster. I guess they have their reasons and I'll give it a try and see

Not surprising that this would be their advice. Personally I would not introduce any solvent/cleaner (and that is what this is...) to the engine without changing the oil afterwards. Adding the cleaner to the fuel or brake booster will allow some of the solvent to get into the oil. It will act just like fuel in the oil (fuel dilution), and thin it out. Now, whether this amount is significant enough to matter,,, I don't know. But I will tend to fall on the conservative side and get it out.

I use either Seafoam or Techron at periodic intervals and will only add it prior to a scheduled oil change. I just see it as an easy CYA thing to do.

 

New to forum, just found it yesterday, figured I'd give you a little info on my experience with seafoam. Guess you could say it is, in my opinion, the reason why I had to buy the tacoma.....

Had a Ford 150 1990 with a 302, ran solid with 125K on the clock. Loved the truck, was dent free, and flawless. Heard about seafoam and wanted to "clean out" all the crap that I thought had to be inside of it after so many years. Put a half a bottle in the brake booster, then a little in the crankcase, smoke blew out like crazy, I expected this. once the smoke cleared, I got to work changing the plugs and oil. Got about 1K rough miles outta that truck after using seafoam. Guess it did indeed break loose all kinds of crap and crapped out my valves and oil pump (never did tear the engine down to find out what it did, it just never ran right afterward, ran like absolute shit, and I was so mad at myself for doing this to my truck)

If I could do it over again, I wouldnt put it near my car/truck. Why on earth would you want to do it UNLESS there is a problem anyway with the vehicle??? I say, if its not broke, dont fix it.........took me a truck to learn that one. But hey, now i drive a Taco so Thanks Seafoam!!!!

 

Yeah...I never would have recommended you using seafoam on an engine that well broken in. There is a something to be said for the gunk holding stuff together in older engines. If you do it regularly...Probably no big deal..but not a one time thing with an engine that old.

Glad it got you into a Taco tho!!!

 

Thanks, I'm glad I got the taco as well!!! 75K and not a single issue, and its been offroaded and used quite a bit. Very happy with it so far. As far as the ford goes, live and learn(and dont learn from someone at work who talks up a product like that.) I agree that if its used often since new, it wont hurt as much, but on older engines forget it. On the taco I've only used mobil 1 5-30 in the engine, and I see no need or reason to think that its "gummy or dirty" inside. It did take me awhile to get over the ford because of my bad and a ten dollar bottle of crap, but live and learn.

 

Just use seafoam in the brake booster and fuel tank...
