It was love at first sight! My Satin Jade Pearl 300C with minimal options and a Jade/Greystone interior. Sitting there waiting for me to take her home. I've been contemplating buying this exact same car for almost a year now, and here it was at a local dealership fresh off the truck! After the usual once over, I went inside to get the employee price on my Jaded Jewel. My wife and I were just looking, but ended up driving it home that afternoon, What a feeling to look and buy all within a couple of hours. I've bought many cars over my 60 years, but never looked and took it home on the same day! One of the formalities at the dealership was to meet the sales manager, as well as the service manager and ask any questions regarding your purchase. The young lady service manager asked if I had any questions about servicing the car. I did. I asked about oil capacity and how often I should have it changed. She told me that the 5.7L Hemi required 10 quarts of special oil, not synthetic,and since I am a retiree and don't put on a lot of miles, I should consider having my oil chaged every 1500 miles right at the dealership for there $49.95 special price! WHAT THE HELL was she talking about? I told her I usually change my own oil, and I would put in Mobil ! just like I do in my VETTE, she said absolutely no synthetic should be used in the Hemi! Plus it is difficult to change because of some bracket that needs to be removed. Whoa! Anyway, I knew I wouldn't be taking my car back to that dealership for anything. Long story/short...I called a friend who has a 300C also and he tells me he just had his first oil change at the dealer and they used Mobil ! Synthetic, 8 quarts plus filter and it cost $79.99 for his oil change, and his salesman picked up the tab! I get home and reads the manual, it sates 7 quarts 5w20 , and synthetic is ok if you want. Are these service managers that are trained by daimler Chrysler on the same page? WHAT DO YOU SAY???? Any comments?
