When to add fuel additives

[Kira]

I read Techron works on cleaning fuel injector nozzles upon shutdown. Therefore, adding it before a stint of local driving is what I do.
I cannot remember the source of this info.

RELATED ANECDOTE: My friend's '97 F-150 4.6l had a minor hiccough which I could NOT for the life of me hear.
I gave him a 20 oz. bottle of Techron Concentrate Plus for his birthday.
He claims the engine has smoothed out.
I haven't been near the truck lately so I can't comment.

I recall seeing something from Chevron on that subject some years ago, but I can no longer find it. Anyway, the message was that Techron is most effective when used in day to day driving because that allows greater soak time.

I agree that it's better to use fuel additives/cleaners when expecting several shorter trips vs. one huge highway run to burn the tank of treated fuel. But I also wonder about the effect of reduced fuel economy during several cold starts (more open loop operation) vs the maximum fuel efficiency scenario of a long highway run. Probably doesn't matter much either way... I would choose the several short trips scenario if I had to choose when to run a fuel cleaner/additive.

I add the Stabil 360 at every fill up. I have found it lengthens the time between throttle body cleaning intervals. Cheap insurance to keep my bike in top running condition.

I'll be adding a can of B12 to my Wrangler this week. It will see normal driving [10-100 mile trips, with shut off soak time, no extended runs] between now and when I change the oil. I have 500 miles before an oil change is due. That should give me at the very least one tankful with nothing but fresh gas before I change the oil. I like to add FI cleaners at least one or two tanks before an oil change.

Use Chevron, Texaco or any top tier gasoline on your trip and have fun.

Before each oil change so 5-7K typically/3-4x a year. Liquimoly Jectron. Just dump it and drive normally....here I'd do it on my trip for sure.

I have never seen the effects of any additive show up in a UOA including running E85. What is supposed to happen?

Gumout did their last test on their one-n-done product doing a full highway drive, no stops, no turn offs.
My car barely comes up to temp on my short drive to work.
I try to use the additives in our cars when we go for long drives. Full temp operation seems better to me - - but that depends on your daily commute.
