If my understanding of the instructions are correct: It saids to pour content of Techron into a nearly EMPTY fuel tank and THEN immediately add gasoline--what is the point of this? Is this not the same as pour a the Techron into a FULL fuel tank???
o.O ?? ?
Also, is an oil change necessary after application ?
Why Techron on a nearly empty fuel tank?

It's to ensure full mixing.
Yes, it's for fuel mixing. You can pour it in a 1/2 tank of gas, but fill it up after you pour it in for mixing. Then run the tank almost empty before you fill again. I believe instructions say to use every 3-4K.
Sometimes people ( bitog posters ) will use Techron in a near empty or half full tank for the purpose of having a more concentrated cleaner go through the system. YMMV
You might be confusing that with the instructions on the bottle which tell you to pour the contents into a near empty tank and then refill it. As everyone is telling you, that's so it gets mixed well, and that also creates the official factory recommended concentration.
No, an oil change is not necessary after using Techron, unless it's time for one already. Some people use fuel additives right before an oil change, that way if anything DID contaminate the oil it gets tossed with the old oil.
I think normal driving will mix it pretty well within a few minutes if you added it to a full tank.
Not to insult anyone but, there is a check valve at the end of the fill tube going to the gas tank. Actually it's inside the gas tank. This is nothing more that a spring loaded flap which remains closed. Pouring anything down the fill tube will certainly not have enough force to open the flap. Driving around may allow the fuel system cleaner to slowly seep past the flap and get mixed into the fuel but, not ideal for proper mixing. Pouring the fuel system cleaner in first(wheather the gas tank is half full or completely empty) and then filling the tank is really the only way to PUSH OPEN the flap and allow for proper mixing. This is the whole reason for pouring the cleaner in first and then filling the tank.
First I've heard of that. Makes since to me.

I have also heard about people who run it concentrated for a few miles and then go ahead and fill the tank. I have no idea if this actually helps or not. Like a lot of things people do to their cars, it's probably just another "feel good" move.
There MAY be a check valve in the filler tube.
And if there is, it is not a seal - the cap is.
A fluid will drain down it nicely.

Correction: "It makes good sense"...not, "I make good sence".

PepBoys has buy one get one free Techron, no mail in rebate on the smaller bottle.
