And VERY important, Ram issued a TSB (Technical Service Bulletin) that states you MUST wait 30 minutes after adding oil before starting the engine to allow the oil to properly drain throughout the engine. Otherwise, you risk catastrophic engine damage. And we must agree, as we are aware of two EcoDiesels that required complete engine replacements after dealers made the fatal error of starting the engine too early.
    Anyone heard of this or the tsb that states this??

    I don't think anyone has ever produced a copy of the TSB so I can't verify.

    I thought it was 30 minutes to drain completely, but here is a TSB not sure it's the only one but it's from the summer of 2016 when things changed...

    This says nothing about draining for 30 minutes just 5 minutes.

    Warmup engine (10 minutes - a pretty long time), Drain completely (5+ minutes), start engine for 1 minute and check fluid level is exactly in range.

    The TSB is on this post: https://www.ram1500diesel.com/forum/...hange-tsb.html

    on page 3 of the PDF file found in post #2 of fxober's link to another thread , , step # 8 of the TSB , in which FCA asks the dealers to change the oÔl to be 5W40 , they write :
    ..
    "" 8. Remove the oil drain plug and allow oil to drain for at least 5 minutes or until it stops dripping."" ....
    .that TSB looks to be for brand new trucks on the lot
    because in step 13 , page 5 , they write " do not reset oÔl life message on any new vehicule (Under 500 miles) ".
    ..
    about the 15 minute wait after filling up with oÔl , we have this : seems genuine because it is found on " All Data " site.
    found here , post # 42 in here :
    https://www.ram1500diesel.com/forum/...tml#post902036
    ..
    so........I will stick to the step by step I scotch taped to my garage door .

    Domino , I found another thread where the theory is 20/20 wait ...https://www.ram1500diesel.com/forum/...in-refill.html
    ..
    also is the same thread where the 15 minute wait was dismissed by 97hmcs , BUT , later
    in another thread , Brokendownbutgood posted the same image , but this time , it was noted it came from a site where mechanics go to
    for information , and now seems to be genuine .

    the origin of the 30 minutes drain is in here , https://www.dieselpowerproducts.com/...e-filters.aspx
    ..
    it is from a long time ago , and was dismissed by other members , like 97hmcs in this other thread , post #2:

    There was a revision to the tab, rev A. Still do not see anything about waiting 30 minutes. The all data 15 minute wait is interesting. Still seems like a long time for synthetic.

    My guess is that alldata carried it over from the jeep CRD. Just because it's alldata, doesn't necessarily mean it's 100% accurate. I have never seen anything from Mopar's TechAuthority.

    Mopar TechAuthority is where FCA trained technicians go for information.

    Allowing the vehicle to sit after new oil is to make sure the oil gets past the oil pickup sump and screen.

    It was a large industrial piston type compressor, it used 10w oil. After a rebuild, with new oil, apparently the cold oil didn't flow through the screen to prime the pump, it seized in about 20 seconds after I turned it on for the first time. Man the boss was pissed! lol

    Yea, I would wait, go have a beer or coke or something.

    The EcoDiesel tech at the dealer I go to swears that when he attended class for this engine, they told him the same. You must wait 20-30 min before starting after adding the new oil. This dealer only does oil changes on EcoDiesels if the customer is fine waiting an extra 30 min. I've done it this way the last two changes on my truck, and both times noticed that when I start the engine, there is none of the typical clatter that you normally get for a few seconds after changing oil. This has been discussed before, and I know others call baloney, but its an easy thing for me to do while I put tools away etc, and costs zero $.
