I just filled the car up yesterday, and forgot to put the Techron in. My normal habit is to put the Techron in the the fill-up before I change my oil so that it is a complete tank of gas used with Techron before I change the oil. Anyway, I have a full tank of gas, I want to change the oil next week. Will adding the Techron now mix in the gas while driving or will it stay concentrated and not mix well?
Can I add Techron after fill-up?

You can. Me being weird would just drive to the gas station, throw the Techron in and top of the gas tank.

I'd wait till down 1/4 take. Add the Techron and fill it up. IMO, it will make little or no difference when you add it.

+1, this is what Id do too.

Just put the Techron into a 1/2 gallon of gas and pour it in using a small handheld tank
I think the techron will mix as you drive around; in fact it will be mixed the firdt time you hit the brakes.

I think the issue is not the mixing in the tank, the issue is how much will stuck on the filler tube. If you add 1 bottle I think that should be less a problem, but if you just add 1.5 oz Si-1 maintenance dose, I would suggest to pump the petrol after putting the additive so the additive will be washed down to the tank from the filling tube.

yep, biggest "issue" I can see....which is generally why it's recommended that most additives be used "prior" to fill up.....allowing the fuel to "wash away" the additive" down the filler neck/tube.
Mixing is no problem, we're not talking oil and water here lol. The additive is gonna mix no problem in the tank either way....but yea, when it comes to smallish doses of additives, particular for MMO (where you're only adding say 4-5 oz. depending on fill capacity), the marvel mystery oil, being an oil and all, tends to "get trapped in the filler neck/tube....I know I've seen it on my car, so I will usually do a "qick shot" or two of fuel down the filler tube, to make sure it washes down the additive when I'm filling up.....

I just waited until the tank was 1/2 down, then added the Techron and filled up the rest of the way. I think that should be fine. I really wasn't comfortable with adding it to a full tank. Didn't want it to settle or something in get sucked in all at once through the injectors. Don't know if that would have happened, but didn't take any chances.
Techron is MUCH thinner in viscosity than either RL SI 1 or 2, or MMO.
Could some 'stick' in the gas filler neck? Yes, but not like the other two mentioned above.

Cooper,
I do it in anyway as long as it gets into the tank.
