new 2010 owner appreciates advice.....
 

Any advice would be appreciated on the following 4 points:
I have a 2010 challenger SE with sirius radio option and standard 17" rims; all season P215/65/R17 tires..
1-My rear defroster doesn't seem to heat in the uppermost 3 bands (towards the roofline). I spoke with the dealer who states these 3 uppermost bands are from the radio antenna or sirius radio antenna, as both signals do not come in through the rooftop antenna. Is this correct or is a portion of the defroster not working?
2- I need to have better traction in snow conditions of Long Island, New York. What is your opinion on changing to 4 Blizzak W60 (P215/65/R17)tires for the snow season?
3- I have almost 800 miles. Does the group suggest the first oil change at 1000-1500 miles to remove particulates which may come loose from the engine during the break-in period or 6000 miles as in the manual. I'd like to have the car last as long as possible.
4- I'd like to change to Mobil 1 synthetic oil but I read that Dodge doesn't use Mobil 1 synthetic. For oil changes and other routine maintenance, including the required periodic equipment checks as stated in the manual, must I go to the dealer or can I go to my usual trusted mechanic to without voiding the standard warranty? (I did not purchase an extended warranty.)
Thanx

The regular antenna is in the back window, so this is true. As far as wanting to use Mobile One... you can get a Quick Lube type place to change it without it voiding the warranty. Just keep the reciept as a proof of the routine maintenance. Also do not allow then to check the rear end ect. for levels. There is a seal and if it is broken then it voids the warranty. So just tell them the oil and nothing more. That is what I do when I'm outy of town and have to have the oil changed. Tire... I can't help you there. I live in NC and SC and we don't deal with much winter weather. I would wait a while on the synthetic oil. About 6000 miles to let everything settle. Then add the synthetic for the rest of your cars life. Some might disagree but thats my take on it. Good luck and enjoy the ride (even if its slippery) LOL
