When you reach the site, watch the cut scene, then leap into your car and pursue Trevor. Avoid using weapons and chase after him through the crowded freeway. Use Franklin's special ability to weave through all the cars.

When you reach the oil-field a cutscene will kick in. Michael will intervene, wrecking Trevor's car and wounding him.

From here, Franklin has to end Trevor's life. Aim your weapon at Trevor (not the gasoline puddle) to burn him alive. If you do not shoot Trevor, Michael will shoot him for you. The final story mission is completed and Michael and Franklin part ways.
