depends how often you drive it, if it sits for months at a time its a no go, if you go through a tank every few weeks (which with that beast i dont think youd worry about not using enough gas lol) i wouldnt worry about it. i've ran it in my daily pickup truck, 2 years no issues, once again tho, a true daily driver
I tend not to drive them for months in the winter time. Also with five of them and having to rotate them, they just don't get driven much. I would be uncomfortable letting the alcohol set in the fuel system.....
