my jeep has dam near 400k on it is it a good idea to run sea foam through it. ive heard on really hi milage vehicals that sea foam basicaly kills it and that all the build up on the valves and such is what is keeping it running is this true?? if i get it should i just run it through my gas tank or should i not even try it

personally i would run it through the gas tank only and not thru any vacuum lines or oil.

congrats on 400k miles

I have also seen great results and some not-so-great results by introducing Seafoam into the engine.

However, there is NO risk in running a bottle of Seafoam in a tank of gas to clean the fuel system and help optimize the spray pattern of the fuel injectors.

The "stoddard solvent" in Seafoam is pretty darn good.

its a owners choice the way i see it id rather use a injector flush kit my self

I agree for an engine that has "symptoms". For an engine with no symptoms, I would use Techron or Seafoam about every 3-4 months as a PREVENTIVE measure.

Spend $28 on a bottle of BG44K. Works wonders.

I agree. I use BG44K for my most problematic problems where fuel system is suspect.

My favorite additives for cleaning the fuel system. In this order:

1. BG44K
2. Techron (by Chevron)
3. Seafoam
4. Lucas

where can i get Bg44k besides a dealership cuz all mine in town are a$$holes

I don't think that the dealerships even carry this. Not sure what stores do, but you should be able to order it. GOOGLE it.

i did and it came up with this map of my city showing all the places that sell it and they were only dealerships which i thought was realy wierd

If you've kept up with reg mat which at 400K I'm sure you have. I wouldn't think you would have any problem seafoaming the oil. I don't see why putting it thought the tank and vac lines would cause any thing to leak. All putting it through the vac lines does is clean carbon off the valves. I'd say at least tank and lines your choice on the oil. Saying it will cause a leak on an old engine is like saying switching to Synth oil now will cause it to blow up.

Personally, I would be scared *****less to introduce anything to a 400k engine that it's not used to... I definitely wouln't mess with it now if it's not giving you any issues.
