Looking at picking up an 09 Charger with the 5.7 Hemi. I beleive that the vehicle is spec'd to run with 5W-20. Seems like a light oil for such a larger engine. The vehicle is equipped with the MDS.
I heard that anything but 5W-20 will mess with the MDS operation. Is this right. North of the boarder, 5W-20 synthetics are far between, but lots of 5W-30. Anyone have this car or experience with the MDS and other viscosity of oils?
On the west coast, it doesn't get that hot, but I do go into the interior and the highways are mountainous and the car will be subjected to hot summers, 38-44 degrees.
Please chime in shed some light
