I gave a 2015 Titan with flex fuel. I've never used E-15 or E-85 fuel. Any pros or cons? Thx.

My 05 is Flex....use E85 from time to time without any issues. It gives me near the same mileage if not towing....12+mpg v 14.4mpg. Pre hurricane it was running about 1.77 a gal v 2.12 for regular. I don't use it towing. No reason other than it's not easily found to test a long haul for results.
