    okay all you wise gear heads of knowledge...I just found out my car hit the testing stage so it has been driven to check for leaks, sqeaks, etc. so, it will be here soon! I have heard that you should take it easy for the first 500 miles while the car gets broke in. As many of you know, I have some serious plans and they don't involve driving cautiously for the first 500 miles. If that is the case, I will be planning a road trip to Cali and back. Please share your thoughts and knowledge on this. The last thing I want to do is not treat my new baby right. Thanks:D

    From the User's Guide:

    SRT Engine Break-In Recommendations

    SRT Engine Break-In Recommendations: The following tips will be helpful in obtaining
    optimum performance and maximum durability for your new SRT Vehicle.
    Despite modern technology and World Class manufacturing methods, the moving parts of
    the vehicle must still wear in with each other. This wearing in occurs mainly during the first
    500 miles (805 km) and continues through the first oil change interval.
    It is recommended for the operator to observe the following driving behaviors during the
    new vehicle break-in period:

    0 to 100 miles (0 to 161 km):
    •Do not allow the engine to operate at idle for an extended period of time.
    •Depress the accelerator pedal slowly and not more than halfway to avoid rapid acceleration.
    •Avoid aggressive braking.
    •Drive with the engine speed less than 3,500 RPM.
    •Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.

    100 to 300 miles (161 to 483 km):
    •Depress the accelerator pedal slowly and not more than halfway to avoid rapid
    acceleration in lower gears (1st to 3rd gears).
    •Avoid aggressive braking.
    •Drive with the engine speed less than 5,000 RPM.
    •Maintain vehicle speed below 70 mph (112 km/h) and observe local speed limits.

    300 to 500 miles (483 to 805 km):
    •Exercise the full engine rpm range, shifting manually (paddles or gear shift) at higher
    rpms when possible.
    •Do not perform sustained operation with the accelerator pedal at wide open throttle.
    •Maintain vehicle speed below 85 mph (136 km/h) and observe local speed limits.

    For the first 1500 mi (2414 km):
    •Do not participate in track events, sport driving schools, or similar activities during the
    first 1500 mi (2414 km).


    It will be difficult to hold the beast back for the first 500 miles but in the end, I'm sure we'll be glad we did!

    Last weekend I was able to download the 2015 Operator's Manual for the Hellcat. That is where the break-in instructions came from. Its a little better than the requirements back the 392 back in 2011. You had to keep it under 55 mph for 500 miles.....torture...

    Actually, you only have to keep it under 55 for the first 100. Then you can move up to 70 for the next 200, then up to 85 until you get to 500...

    (*gets car, drives 500 miles the first day)

    Crappers! I'm gonna have to hide the red key from myself! I will be using Valet setting for first 500. It's like getting a box of cupcakes and telling yourself you are only gonna have one and pretty soon you are licking the empty box!o_O I cannot be trusted with that much horsepower temptation!:p

    You frequently hear from some "Don't follow the manual if you want the car to be fast; drive it like you stole it." Tempting as it may sound I always figure the advice from the engineers that made the engine and recommending break-in instructions are probably the best ones to follow; there are some subtle things happening to the engine (as well as the rest of the drivetrain) during break-in.
    Varying rpms during break-in is important and I change engine oil at 1500 miles for the first change. Many disagree with the latter but its an old habit and I'll probably continue to do it with new cars. Then drive it like it came out of Hell!

    ..just our experience with our cars but we change the oil in the 1st 500 miles ( then 3,000 miles or once a year whichever comes 1st) on a new or rebuilt motor to get the metal out and then run it like the way you are going to drive it.The 440 in my 68 Plymouth has 14 years on it and after that 1st oil change I drove it at 3000 rpms ( 3.91 gears, 3600 stall conv ) 120 miles to a 1/8 mile track in NC. I changed tires, made 4 passes, changed the slicks back over to street tires, drove it back home to Va.That motor has always been happy. Of course we change the oil every year on it but I do drive it too work and around sometimes. The Hellcat will get a very early 1st oil change under 500 miles ( Mobil One Syn), then once a year since it probably want get 1000 miles a year on it.
