Keep getting coupon offers from RAM for 3 premium synthetic oil changes for $145 for my 6.4 hemi. After reading the fine print, the service includes "up to 5 qts". Called my dealer and she explained that they charged $15 each for the extra 2 qts, so I have to add another $30 on top of the $48. I asked what the regular charge is for an oil change and she told me it was $82. Wow, a $4 savings - all sounds a little fishy to me. When she asked what motor I had and I replied the 6.4, she asked if that was gas or diesel. After a short hesitation, I told her that she should know that and that I'll be using another dealer. Wow, just wow.
