I own a 2015 Ford Escape with 30,000 miles and runs good. My prior vehicle had over 150,000 miles and I used Gumout Regane high mileage fuel?

System cleaner. I still have a bottle of the Gumout and wondering if I used it in the Escape, would the Gumout do any harm to it?

I suppose I could wait until I get 75,000 miles on it before using but I'm a 3000-4000 miles a year driver and the Gumout would go bad before using it.

They are all snake oils. A properly tuned fuel injected engine without a check engine light is running FINE and does not need anything. Stop wasting your money.

Most car manufacturers do not recommend you use fuel additives. Most cars will go 150,000 miles anyway, without special additives. I would suggest you not use the Gumout and just do what Ford recommends for the car.

Throw it away. It never worked on your old vehicle and it never works on any vehicle. These chemicals are for gullible drivers who lack mechanical knowledge.

This is a case of " If it aint broke, don't fix it".

Why? It won't help at ALL

My Ford Ranger had almost 300,000 miles on it and still running strong when I gave it to my grandson. I never wasted any money on fuel additives because I never thought I needed them. Modern fuels are so clean that I think you are wasting your money if you buy additives. I will take that back if you are going to store a vehicle for some time when a fuel stabilizer is probably a good idea. But other than for long term storage, no, I would not use any fuel additives.
