Frequently Asked Questions
Does a 5.7 HEMI need premium gas?
Dodge Charger R/T
Turns out it's also for owners of Fiat Chrysler's Hemi 5.7-liter V-8, as the company recommends 89-octane fuel for this engine.
What years to avoid for the 5.7 HEMI?
The worst years
While the 5.7L HEMI is a powerful and reliable motor, it isn't free from bugs. A few model years, in particular, have proven more problematic than others. Model years 2011 and 2012 stand out when it comes to bad years for the 5.7L HEMI, with 2012 being an especially lousy period for Ram pickups.
How to make a 5.7 HEMI more fuel efficient?
The easiest way to do this is by driving at a moderate pace, but adjusting your vehicle can also help. For instance, a roof rack or an uncovered bed can increase the aerodynamic drag. Removing such accessories and getting a bed cover can significantly affect your fuel efficiency.
What are the drawbacks of a Hemi?
Most experts agree that a major drawback of the Hemi design is that it cannot incorporate four valves per cylinder. And that's OK when it comes to racing cars, which are limited to two valves anyway – but modern cars use an alternative design with four slightly smaller valves that let the engine breathe more easily.
Why does the 5.7 Hemi need 89 octane?
The higher the compression ration of your vehicle, the higher the horsepower. This is why high-performance engines require more octane. If you have the HEMI V8 engine, you should use the 89 octane, if you have the base V6 engine, then it is okay to use the 87.
Does premium gas give better mileage?
No, any fuel efficiency gained using premium fuel would stem from engine performance, not the gas itself. Buying premium gas won't have you visiting a gas station any less frequently, especially with a standard engine not designed to take advantage of premium gas.
