thank you , the 3.2 can tow a larger, heavier trailer with a greater tongue weight on fuel with less octane than the other engine hence I believe the 'do more with less' position is quite accurate.Two separate questions there: 1. The reason the V6 uses "less expensive fuel" is that the turbocharged engine needs higher octane to operate at peak performance, due to its higher pressures and temperatures. But the fact that the lower-octane gas is cheaper doesn't mean it has any less energy content. This is not a case of doing more with less.
2. Heat is also the reason the recommended towing maximum is less for the 2.0T than for the V6. Theoretically, the turbo has enough power and torque to pull the same load, but it'll get hotter doing so, and evidently Jeep has decided that it's safer to go with a lower limit to reduce heat output.
To the members who take exception to some of my mechanical monikers-does a turbo blow air into an engine ?
