Why can side-to-side surge be more dangerous than front-to-back surge in an unbaffled tank?

Pick an answer

1. Side-to-side surge only affects fuel economy

3. Side-to-side surge can contribute to a rollover, especially in curves or sudden lane changes
4. It has less effect than front-to-back surge in every situation
