    There have been some guesses thrown around about how much oil remains if you don't remove the oil cooler drain plug. When I changed my oil, I carefully collected the oil that came out of the oil cooler drain. Here is the answer...

    Between 10 and 11 ounces.

    Yeah... I have to agree that is a lot of oil still in the system... but the need to drain it really depends on how much you drive the car and how many miles you put on it (IMO). Me I generally only put about 1500 miles a year. I have put more on this year but it's just because the new Cat has been so much fun. I suspect I will continue to only put somewhere in the 1500 to 2000 miles annually. So I basically change the oil once a year. (Been changed twice this year) So given that do I really need to worry about 11 or 12oz of oil that will have less than 2000 miles on it? The car doesn't even call for an oil change in that period. Now if you're one of those guys that use it as a daily driver and puts a lot of miles on the car then I would worry about it and drain it.

    I removed the belly pans from my Challenger at around 300 miles and I didn't put them back on. I don't drive the car in the rain so I don't see the need for them.

    Yep. It's probably fine but I'm too meticulous to leave it in there. I got my car on 11/20/14 and I have 2,200 miles on it so far so we do about the same amount of driving. I changed my oil twice so far (300 and 2000). I also do the same once per year oil change just before I store it for the winter.

    Daily driver. 7500 miles since 11 July.

    I'll always drain the oil cooler.

    When I got my oil changed last week at the dealer, they argued that there was not two drains! I was pissed!! They have a video that will pop up with your vin that points it out! Stick two your guns, drain both..
    The oil cooler needs to drain until there is 10-15 seconds between drops!! Thanks to the forum!!

    I believe the "belly pans" are more for underbody aerodynamics than for splash protection. Underside airflow at elevated speeds dramatically effects handling.

    I'm sure they help at high speeds but I don't think I drive fast enough to see the difference. I'm generally driving on residential streets or making 1/8th runs at the local drag strip.

    Please forgive me for butting in here. I also believe that the belly pans are to help improve co-efficient of drag as well as cooling of the oil (in
    the coolers) and coolant in the radiator. I'm no engineer and do not work for Dodge but if it's not important to the car, most auto makers will
    not spend even pennies that are not necessary.

    So it may never make a bit of difference to someone that drives without them, but, it may? Just something to think about.

    I used amsoil full syn and changed the oil at 1300 miles -- and decided to brake it in with 20 min warm ups and lite Revs and maybe put 60 miles a week or so with quick runs and low revs to seat the seals and other internals also seat the bearings on the supercharger with quick revs up to 2500 rpm's on the the engine.

    noticed people are coming down with tons of issues from the tranny shift to the supercharger to the cooling sys and also rough idling
