Perhaps you miss the point - fuel optimization is more than fuel prices. If you're just taking an occasional trip then fuel op is probably not worth the ongoing cost, but if you travel a lot like we do it more than pays for itself. Fuel Op doesn't just look up fuel prices for you, it looks at your trip and figures out the best places for you to purchase fuel and how much to purchase at each location based on what you want for minimum fuel in your tank, tank capacity, etc. For example you may be running low and need fuel along the way, but another 200 miles up the road you could get it for $0.10/gallon less and another 300 miles and it's $0.20/gallon less. Fuel op will see that and suggest that you get enough to get to the cheaper fuel at each stop instead of just looking for the cheapest fuel around where you need to fuel.
On the trip I'm on right now I've saved close to $70 using Fuel Op over what I would have paid if I'd just been looking at fuel prices on one of the fuel price boards and buying it at what seemed the cheapest spot in the vicinity of where I would need to fuel again. I don't think it's ever suggested a Pilot - but to each their own.
