I've been using 20oz. Techron at oil changes, but at my 60K maintenance (and other times if I recall) my Hyundai dealership has been adding "Wynn's"...Wish I would have seen the bottle they used. Perhaps its this stuff? Premium Fuel System Cleaner | Wynn's USA What do you all recommend, if anything? Thank you!

I guess it doesn't make a difference but I have always used Techron.

Techron is the recommended product from the user manual .. at least for my Tucson.. but of course that's [most likely] just because Chevron has the contract with Hyundai, not because it's a superior product or anything like that...

But in the end, do any of them _really_ make a difference? Who knows...

Use whatever

I just use Seafoam every few tanks with 89 octane

I seldom use any but when I do I look for one that has PEA in it as the cleaner. Also sometimes referred to as "nitrogen" cleaner. I usually get the One and Done by Gumout but there are others. Most of the cheap fuel cleaners are not much more than Stoddard solvent or plain mineral sprints. Seafoam is mostly the Stoddard and isopropyl alcohol, no PEA.
