To get an accurate estimate, you'll need to specify the exact year and trim level of the Rendezvous. You can then find the EPA estimated MPG (miles per gallon) on sites like:
* The official EPA website (fueleconomy.gov): This is the most reliable source.
* Edmunds.com, Kelley Blue Book (KBB.com), or other automotive websites: These sites often have fuel economy information based on the EPA data.
Keep in mind that real-world gas mileage can vary based on driving habits, road conditions, and vehicle maintenance.
