Thanks for all the responses. I really appreciate them. I only put one tank of gas in it so far and it was 89. I will continue to run the 89 it is only 10 cents more a gal. and you are right if you buy a hemi why balk on paying for the gas. I love the Mopar 10. I think they only made 500 of them. I see that they made 1000 of the mopar 11s. Mine is #789. I went looking at the Challenger RT's and I lost my wife at the dealership and when I found her she was in love with the mopar 11 Charger. I think the blue stripe and black rims drew her to it like a magnet.long story short she drove it and was smitten.I told her I would get it for her rather then get the Challenger. We are an all mopar family once again(traded in our 2008 Buick Lecerne)I also have a 2000 Ram 1500 5.9 4x4 and my 70 Duster 340. I don't have any pix of the Charger but if you go on ebay they have a couple for sale. They all are made with the same stuff.
