GAS wise. its great, you can get up to 20 mpg on the highway.
15 in the city.
5w30 without MDS 5w20 with MDS
The MDS is all automatic and would not need reset.
The Hemi with MDS, which is most of them, does cycle down to a four cylinder at cruising speed.
Any name brand is ok. The viscosity is labeled on the oil fill cap. 5w30 for non MDS engines. 5w20 for MDS engines.
Performance wise it would be the 6.1L SRT8 Hemi produces by Chrysler motors. Performance/Economical would be the 5.7l Hemi R/T produced by Chrysler motors.
Any grade is fine. It doesn't require premium or mid grade.
5w30 or 5w20, depends if it has MDS or not. If the oil cap does not say 5w20, use 5w30.
Yes. The Hemi needs 5W20 for the MDS system. The V6's need 5w30.
A hemi engine refers to one of the most popular high performance engine types.
Multiple displacement system. The 5.7L Hemi will drop down to 4 cylinders under light load to conserve fuel.
any 5w - 30 oil. Use what ever the oil cap says. The Hemi with MDS requires 5w20 for example.
Dodge recommends 5w20 in the HEMI engines, because the higher viscosity of 10w30 can lead to inefficient operation of the MDS, or damage to the engine at hi revs while in MDS mode. It's always best to use the recommended weight of fluids.
