The Jeep Cherokee 3.7 V6 is known for its high fuel consumption. Average combined figures typically range from 15 to 17 miles per gallon (mpg) US (approximately 15.8 L/100km), with real-world usage sometimes being lower, especially in urban driving[6].
Owners of the 2006-2008 Jeep Cherokee and Grand Cherokee models with the 3.7 V6 commonly report:
- About 15-16 L/100km (roughly 15-16 mpg US) on the highway, and over 20 L/100km (roughly 12 mpg US) in city driving[2].
- EPA ratings for the 2008 Grand Cherokee 3.7 V6 are 15 mpg city, 19-20 mpg highway, and 17 mpg combined[5].
- User-submitted data for mixed driving scenarios often aligns closely, with reported averages from 17-18 mpg in combined conditions[3], but some users experience much lower figures—down to 10 mpg—due to mechanical issues or short city drives[4].
- European data for the Grand Cherokee 3.7 i V6 4WD (210 Hp) 2004-2017 lists a combined fuel consumption of 15.8 L/100km (14.9 mpg US, 17.9 mpg UK)[6].
- Typical owner-reported values fall within 12-14 mpg in city and 14-16 mpg on the highway for city and highway driving, respectively[1].
Overall, the Jeep Cherokee 3.7 V6 is considered a “thirsty” engine, sometimes even less efficient than Jeep’s larger V8s, according to user discussions[2].
