'Does all 2004 RAM 1500 Hemi have MDS'?
Not all 2004 RAM 1500 models equipped with the Hemi engine have the Multi-Displacement System (MDS). The MDS feature was introduced in the 2005 model year for the 5.7L Hemi engine, allowing the engine to deactivate four cylinders under light-load conditions to improve fuel efficiency. Therefore, if you have a 2004 RAM 1500 Hemi, it will not have MDS.
Do you have to use 89 octane fuel in a 5.7L 04 hemi?
No. You can use 87. 89 is reccomended because of timing and fuel quality. The hemi has a high compression ratio, and with MDS active, any fuel that is in the cylinder could be more suseptable of detonation with lower grade fuel. However 87 or 89 will do fine. The use of 93 octane wont help at all. Its not needed unless the engine specs call for it.

Is 10w30 good for a 2006 charger?
