Mixing oils in turkey deep fry

Hi,
I am going to deep fry a turkey (actually two turkeys, one at a time) using the turkey fryer my dad gave me last Christmas. I haven't used it before, but it looks like the 2.3 gallon jug of peanut oil that came with the fryer won't be enough for these 10 lb turkeys. I might need another 2 gallons of oil, but I couldn't find any bulk peanut oil on sale where I live, so I bought 2.5 gallons of regular vegetable oil. So my question is: if I mix the peanut and vegetable oil, will that make much difference in the final product? Will it be okay?? Thanks for any suggestions!
