* Vehicle type: This engine was used in a variety of vehicles, from heavy-duty trucks and SUVs to ambulances and motorhomes. Heavier vehicles and those with less aerodynamic designs will get considerably worse gas mileage.
* Driving conditions: City driving, towing, and off-road use will drastically reduce fuel economy compared to highway driving.
* Maintenance: Proper maintenance, including regular tune-ups and tire inflation, can impact fuel efficiency.
Therefore, giving a single MPG figure is misleading. However, you can expect generally low fuel economy in the range of 8-12 MPG in mixed driving conditions. Highway driving might see slightly better results (perhaps up to 15 MPG), but city driving will likely be significantly lower (possibly as low as 6 MPG). Towing or heavy loads will further decrease this.
It's crucial to understand that the 6.8L Triton V10 is a powerful engine designed for work, not fuel efficiency. If fuel economy is a primary concern, this is not the engine for you.
