Ferraris drink premium fuel enthusiastically. Expect 15-20 liters per 100km in mixed driving, worse if you're pushing it. I got about 18L/100km in the 488 through Octane Rent. Premium 98 octane costs around 3.00 AED per liter in Dubai. Tank capacity varies - usually 70-90 liters. So full tank refill costs 210-270 AED. Advice from
https://www.therooftopguide.com/rooftop-news/rent-a-ferrari-in-dubai.html on fuel: return it full to avoid refueling charges (companies charge premium), use Shell V-Power or Enoc 98, don't economize on fuel quality with supercar. For full day rental expect to spend 150-300 AED on fuel depending how much you drive and how hard you push it. Highway cruising is more economical than city traffic with constant acceleration. Budget 200-250 AED for fuel as safe estimate. Small price to pay when you're already spending 4000+ on the rental.
