I would for an older 7.3 powerstroke. Newer truck would most likely do an injector cleaner every couple years but not a daily fuel additive. Archoil gets really good reviews and cheap on amazon. Think its more designed for older stuff like the 7.3. They sell daily additive and also a bottle of injector cleaner. Oil treatment as well. I buy the 3 pack that contains each of them.
Although I only had my early 99 Superduty 7.3 for nearly 16 years , bought new , never put a drop of fuel additive in it. Was running just as good as the day I bought it when I sold it . It appears some are drinking the koolaid . And ran a lot of the low sulfur fuel in it .
