![]() with 93 octane costing approx 20 cents more than 87, do the math.
12,000 miles/yr @ 13mph = 923 gallons x 20 cents = $185/yr extra I'll use 87, save the money, and rebuild/replace the engine when it dies using the money I saved, its cost effective and I see NO performance gain using 93 on a stock motor. that is why FORD did not recommend or require 89 or 93. Keep in mind this is on a stock daily driver. If your a track guy, or highly modified, thats a different story.
