Or is this just a big scam by the ancilliary auto accessory industry?

Depends.

The best bet is to use name-brand gasoline with good detergent additives. Injectors will last a long time if you do that.

Also, use the proper engine oil (weight/viscosity) and you'll probably never have any internal engine failure.

I'm not a big fan of any additive, except maybe gasoline preservatives.

Generally, they're a scam.

Certain fuel additives like biocide for diesel or stabil for gasoline are very effective at what they're meant to do. Stop-leak additives also work for band aide fixes but can do more harm than good sometimes.

I'm not aware of any engine oil additives that provide any appreciable benefit.

Using quality fluids that meet or exceed manufacturers specs will generally negate the need to add anything.

No on the oil additives (unless detergent cleaners), and yes on stuff like quality fuel injector cleaners

I have friends that swear on Seafoam and penzoil fuel additive. I never used any of that. I do use name brand fuel but never an additive. I stay on top of my engines though and never have had a problem.

That's the key, IMO.

Good stuff. I use it every winter to store my small engines, with a full tank of gas. Can't recall any past issues come spring time.

As for fuel cleaners, some of those use a good amount of methyl ethyl keytone which is a powerfull solvent. I wouldn't reccomend using those as a regular additive during fillups.

Seafoam is good stuff when you have "carburetor removal denial syndrome" and want a quick fix for a gunked carb. Won't always worked, but its worked for me a few times.

It's a solvent though, and definitely not recommended for every fillup.

If you use seafoam properly, it does amazing things as far as removing the carbon build up. I've used it a couple of times on my LS camaro and I've noticed the car just runs smoother afterwards. Also have used the marvel mystery oil in my mower and it seems to help.

I have been putting regular gasoline in my 2010 F150 since the beginning with really no additives used (maybe a detergent additive once a few years ago?). Would I benefit from using a Seafoam or something else for my next fill up? What would be a good recommended additive/cleaner to help performance and health? Nothing unusual going on or anything. I did change the fuel filter about a year ago (80k miles) but not much else.
