well lets see... it will clean the inside of the motor.. yes..
but where do you think everything is going to go?
the filter isnt going to catch the stuff that sinks to the oil pan.. that will then get sucked into the pickup screen. then clog it up.. killing the motor slowly..
it will also remove the "old oil" thats keeping the seals from leaking..
think about it before you try to flame me...
to each their own..

anyways back on topic.

My beast has 250 000 miles on it! Should I use this or do you think that the carbon is the only thing that is keeping the seal? Do you think this will help with throttle response?

should be fine to use on the upper intake, just do it through the the brake booster vac line. i myself wouldnt use it in the oil.

Oh for the love of god with the propoganda, have you EVER torn a motor down???? Do you have any idea what seals you are even speaking off? I can think of THREE, count em, THREE peices of rubber in a freaking motor man. It's absolutely cool to say "hey I was wrong" but to continue to spew this at me and everyone else is a true excercise in futility.

It's not flaming, it's just me trying to dispell a rumor before it starts. Tell me this, what do you do for a living? I myself am a certified aircraft mechanic, hydro mechanic, and Avionicsman. As a shade tree job, I build hot rods and by shade tree, I mean I put out cars as fast or faster than many of the shops out there and I do it out of my personal 2 bay shop. I have been through enough engines from American to Japanese to (dear god) German to know exactly what touches oil and what doesn't. I have no idea about these seals you speak of as 99% of an engines seals are METAL!!!!!!!! There is nothing going to sink to the bottom of your pan, there is nothing going to clog your pickup, you stand a greater chance of killing a motor with a crappy PCV system and going mudding once than you do putting 1/3 a can of seafoam through your engine and cleaning it out. The LACK of lube from not keeping it clean is going to be much more of a hazzard.

Once again, this is not a flame or a bragfest, this is simple fact. When people start to try to be the man online and no one knows where they got their info, a large part of the time, it's from some other dude who was the man online but never made it past changing his oil and putting some pretty colored vacuum hose on his motor.

Jay calm down man, relax.

daniel has grown up around cars all his life , he has watched hid dad tear down countless numbers of motors and transmissions, rear ends, entire cars.

he has seen what some products can do to motors inside and out.

BTW his dad is master ASE and state certified and fixes state police and secret service cars for a living.

some ford motors are known for sucking the oil pan gasket into the pan and clogging the pickup, not to mantion almost all of the older ford motors are known for having leaky rear main seals. and there is more then 3 rubber seals in a engine. theres at least 12 rubber "valve seals"

running a higher octane than is required does nothing except make your wallet thinner. Newer vehicles have anti-knock sensors, so on a stock vehicle 87 octane should be all that is required unless you change the fuel/spark curve. I tried higer octane fuel and actually noticed worse gas milleage. Now that I have the bama-tuner I have to use 93 octane, being the spark curve requires it with the 93 performance tune. With the tuner I am actually getting slightly better fuel milleage than I was stock, but with MUCH better performance. The savings in fuel milleage for the most part offsets the higher cost of the 93 octane fuel.

89 octane

I use 89 octane in my 3.0 It is a 1999 with 66,000 miles. It pings on 87 octane when going up hills, and hard acceleration.
