Should I dump the break-in oil at 500 miles and start running
PP or RP at 500 miles or wait till 3k or so and then change it.
What is the best oil for this engine??
Help!!!Its the last new car I will ever buy so it has to last

I guess everybody wants the Hemi and he giving me 3k off to get the 4.7....has lots of 4.7 setting around the lot
Is the hemi that much better engine?
To the OP;
1 - in response to your original post. The older( 99-07 )4.7L at just 235 HP was vastly under powered for the Ram and especially the QC( I know I had one ). The newer 4.7L at a much improved 310 HP is a lot better suited for the heavy Ram trucks. However, with that said I would personally opt for the HEMI as I have done on my last 2 Rams over the 4.7L. More power, better resale value, and MPG is as good or even better with the 5.7L( not due to MDS which is useless but because it does not have to work as hard to move those heavy trucks due to the increased power ). Hands down I would take the 5.7L over the 4.7L of any year.
2 - In respponse to your second post about the $3K off. There is a current $2500-$3000 rebate available on the Ram truck's( $3000 for Crew Cab models & $2500 for Quad Cab's ) according to the Ram site. Be sure that is an honest or extra $3K being taken off by the dealer as incentive to move that 4.7L and not a bunch of number manipulation to make you THINK you got a special deal with a factory rebate being shown as money taken off by the dealer. These rebates apply to 5.7L trucks too. Make them show you a break down of the price including rebates and any money they have taken off the sticker( shown individually not grouped together )to be sure they are not trying to pull a fast one with a mfg rebate. VERY COMMON trick by underhanded dealerships.
The new Ram is a great truck and both the 4.7L and 5.7L are pretty durable. I personally would never buy a 4.7L again after owning a HEMI. As said the power is better, the MPG is as good( better for me ), and resale is a big difference between them in favor of the HEMI. Just recently they had a no cost HEMI upgrade promotion. I think it is over but may be worth investigating.
Good luck with whatever truck you choose.
Oh, about oil. Changing the FF at 500 miles and going to a synthetic is fine. PP is a very good oil and so is RP. I run RP in my vehicles and my Rams and they have always done great on it. Unfortunately, with a new Ram under warranty RP does not meet a critical aspect( to Chrysler not your engine )of your warranty needs. It does not carry the API Starburst seal as required by Chrysler. RP is API certified but only to API service level SL.
To carry that Starburst seal, in addition to meeting certain emissions and fuel economy standards, the oil must 1st be certified to the highest current API service level which at this time is SM. So RP, while a very good oil, is not warranty acceptable for your new truck. Just an FYI for you. If you really want to use it they do offer a supplemental waranty where they will step in and cover any repair( engine/oil related obviously )if you are denied because you used their SL oil in a vehicle callling for SM/Starburst( conditions apply ).
Also, stick with 5W-20. The new 4.7L was built and designed to run on it not 5W-30 like earlier 4.7L's. Chrysler is VERY picky about following their requirements for stuff like this. Stay with the correct weight and change it on time. Your call on using the RP. I am using it in my 08 5.7L Ram because I feel it is worth the risk. I have a great dealer as well that will try their best to help me out if something happened. I do know however Chrysler may use that in the even tsomething internal happened to my engine as a way out.
Here is the warranty from RP( note Photobucket seems to be having issues this morning so the 2 pages/images may not show up or may take a while to appear until Photobucket gets back up to speed ).
