Does Gumout with PEA Improve your Truck's Miles Per Gallon with DE Nichols

I've tried a lot of fuel additives to improve my miles per gallon. They usually don't do much, and the one time a fuel system cleaner made a huge difference for me in 1998, the results were kind of terrifying. Maybe that's why they're subtle and gentle? They're avoiding lawsuits?

Scotty Kilmer did a big push on Gumout with PEA years ago and as soon as the ad campaign started I couldn't find one Gumout product that was on the shelf which was available with PEA. Either he sold it out, or Gumout made an advertisement push, then dropped the only chemical proven by scientific journals to actually clean up engines. At least according to Engineering Explained, PEA or polyetheramine is the only chemical which has peer reviewed journals proving that PEA can do for an engine. I think most of us know and can agree that Engineering Explained is a reliable part of this community and a solid source of information.

Well, Gumout in the last few years has had PEA back and when an AutoZoner pointed out what was on sale, I figured why not. I'll make a YouTube video and it's good to run a cleaner as a part of maintenance every once and a while.

And thus this video was born. I really didn't get a MPG boost during the test but you could say that since TCW3 gives me approximately 2 more miles per gallon, not losing 2 miles per gallon by skipping it may have meant that Gumout's Regane actually worked.

My truck's miles per gallon is steadier than you can expect. It's amazingly consistent. My larger tires cost me a couple MPG's, but really, with every turn I'm going farther so my engine is just going less miles per the actual distance. I truly suspect that my gas mileage has remained unchanged. When I first got the truck I did a few modifications, which helped it's gas mileage and it's been the same ever since. I'm happy to say that this winter didn't knock my miles per gallon down 2 points like it normally does so I do suppose I do have some deviation.

Note: Scotty Kilmer did his test on the Gumout Complete Fuel System Cleaner. It must have been a product that Gumout immediately ran out of or changed their labeling to stay fresh on the shelf. I've noticed they switch up what they lookout and their products contents sometimes twice in 6 months. The Regane has been more consistent so this review may have a bit more longevity against what's currently available on the shelf.
