Engine additive

Has anyone used SeaFoam Fuel Injector additive in their Ford V10 engine?  If so, did it improve performance, gas mileage, etc.?

Lucas Oil Fuel Treatment is THE good stuff.
With a heavy vehicle and varying road conditions it’s difficult to measure changes in performance or mpg. But in high performance cars you can actually hear and feel the difference in how quickly the engine revs. This stuff really works.

I have used sea foam in stuck or gummed up Carbs etc but generally speaking I’m not an advocate of using additives in modern engines. Modern gasoline comes with additives that assist in keeping things clean for the most part. Just my 2 cents. That aside adding sea foam to a tank of fuel won’t hurt anything and as far as an injector type cleaner it’s probably one of the better ones. Is there a reason you feel the need? Rough idle etc?

 Don’t expect and mpg increase or  to feel any difference in performance. You will find an improvement in ride however as one can only treats about 20 gallons so your wallet will be lighter. 😁

After adding sea foam, went about 20 miles, check engine light,    Plugged o2 sensor.  Works too good!
