Vehicles that have been tampered with, or repaired without prior authorization from Mighty, may result in not honoring the claim. A statement from a qualified mechanic or repair implication must be provided in writing and signed by the mechanic with a detailed explanation of the findings. Claims for improved fuel mileage are excluded. Mighty’s VS7 fuel products are formulated to help maintain a vehicle at its optimum performance level.
