There's really only about 30 useable gallons in the tank. You're pushing it beyond that. The fuel pick-up is above the bottom of the tank a bit so it won't pick up any sediment.

FWIW, the most I ever put in was 29.5 gallons in the middle of freaking Nowheresville, KS. I really thought I was going to "run out".
