Re: Premium fuel?
Hi Joevano,
It is true that the Crossfire will run with lower grade fuel, it is highly recommended that you use the manufacturer suggested fuel. Although filling up with a lower grade fuel may save a few dollars on each tank, it may cost you much much more down the road.
The Crossfire’s 3.2L V6 10.1:1 compression engine is equipped with knock sensors to adjust engine timing to compensate for the lower grade fuel. Not only will using 87/89 octane fuel increase harmful emissions, lower overall engine performance and reduce gas mileage. But prolonged usage may lead to stalling, hesitation, hard starting and possible premature engine failure which may not be covered under warranty.
The crossfire is a premium vehicle and requires a premium fuel for maximum performance, reliability and enjoyment. If you want to enjoy your vehicle for as long as you possibly can, I would strongly urge you to stay strong at the pumps and resist the temptations of cheaper lower grade fuel.
If you have any other questions, please feel free to ask.
