Would using high quality oil additives for rattle at start-up be helpful?

Is your truck louder since you changed to synthetic oil?
I would wait til next oil change, and use a good premium oil, and get the factory Nissan oil filter and see if the engine quiets down.
If you look in the owners manual, Nissan doesn't recommend synthetic. This is probably one of the reasons why.

I second this response, my truck has never ran better. Mobile 1 0w-30 in mine also
And every manual, for every car says they do not recommend synthetic oil except for manufacturers like BMW that put Mobile 1 in from the start. This is simply because of warranty purposes, if you put in synthetic oil and then try to get Nissan to pay for something that goes wrong they are not going to. People and vehicle manufacturers are still afraid of synthetic oils because it is still kind of a new concept, but the truth is that they run so much better on the synthetic.

actually before they can deny you warranty work they have to prove without a doubt that the cause of the problem is directly related to the use of synthetic oil. and they aren't too worried about synthetic oils per say its the changing of viscosity that they don't like since the motor was designed with specific weight oil in mind when it comes down to clearances. but anything that doesn't come on or in the truck from nissan isn't going to be recommended by them. i'm not saying 0w-30 is bad or good but if you think about whats really going on at start up simply changing oils isn't going to stop it. upon a cold start up there is a lack of oil in all the parts and there really isn't anything you can do to stop that from happening. if what your hearing is lasting more than a few seconds on startup then its something different going on, you may be hearing piston slap which lasts pretty much till the motor is warmed upI second this response, my truck has never ran better.

Some say they have had luck with different oil filters like Mobil 1, Purelator Pure One, and Wix (or NAPA Gold). They have some sort of anti-drainback valve in them.
You switched out your engine oil at 750 miles correct? I personally would have waited until at least the 1200 mile break in period, but more likely the 3k mark. Some debate that their is engine break in additives in the oil and you need to leave it in there, while others say that's old school and doesnt matter. Regardless, I would wait.
I have also read that it is best to run conventional oil for the first 10k, but again just like everything else it could be internet myth.
Honestly, I dont think there is an additive you can add the quiet the noise. I think most people have it and its somewhat normal. For some I think its louder depending on their climate. After about 300 miles mine was very noticable and that was in the summer. Now it doesnt seem as noticable for some reasone. Weird.
In my truck I will stick with 5w30 not sure on oil type as the dealer changed it last time. Probably Castrol GTX, Synblend, or Mobil Clean 5000. I like to stick to the 3k OCI so full synthetic is a waste for me. Probably a Mobil 1 Filter as I was looking at one at the store yesterday and I like the way they were constructed.

I switched originally to 100% synthetic 5W30. Shortly afterward I started to get a little bit of lifter knock on cold starts. About 5 - 10 minutes afterward it would go away. However, I could hear a slight tapping at times as well whenever I would idle.
I have heard the sticky lifter sound many many times. I put in CD2 Oil Detergent (from AutoZone) and within a week the lifter knock was 100% gone. It has never come back. Just recently got lighter synthetic oil and (5W20) to get a little better mileage and better performance. No issues and I would NEVER go back to regular oil now.
IF you are getting a little bit of a lifter knock, or a sticky lifter, then I would strongly encourage you to consider using CD2. I swear by the stuff! It is just a concentrated form of the detergent that the oil bottlers already put in motor oil now (regular or synthetic). But, after stumbling onto CD2 about 20 years ago I SWEAR by the stuff! I have never used any other additive or chemical that I know and can prove works better.

CD2 indeed worked quite well quieting lifter noise in my old car, but I have one caution if CD2 is used on a high mileage engine. My old car had 200K Miles on it and CD2 unseated a lot of gunk. Luckly, I happened to change the engine oil within a week after the CD2 and the oil was black as tar and the filter nearly plugged. I doubt most of our Frontiers have enough mileage to make this a problem, but I thought I'd mention it.

What makes me wonder is why I have the noise to start with? It now has just over 1600 miles. Should be clean on the inside.

I've used mobil 1 since I got my truck but recently switched to royal purple at 77k miles. Start up knock is completely gone after switching to royal purple. I've also heard from some other people (Z people in particular and one guy from Uprev) that "mobil 1 isn't bad for your engine but I wouldn't put water in my engine either"... Just thought I would share my personal experiences.

Oil additives are a bad thing. They are snake oil at best, and at worst will damage your engine.
Rattle at startup is (somewhat) due to oil draining back in the pan. That can be stopped (to an extent) with a decent oil filter that has a good drainback valve.

I've always associated Shell's Rotella with diesel engines. Are you running a diesel or is this one engineered for gasoline engines too?

has anyone ever tried out the motul 300v oil, its pricey, well very pricey at $13 a quart it was co-developed with the engineers of NISMO, Motul and Honda Mugen Japan GT Teams as well as the Subaru World Rally Team and is widely used by many racing teams and manufacturers including PRODrive, Formula Renault, Subaru World Rally Team, Japan GT Nismo, Honda Mugen Team, Ferarri 550 Maranello, Le Mans 24H, Formula 3, FIA GT, French GT, Porsche GT, well the list goes on. i've seen many claims that this oil is very good at eliminating metal on metal dry start ups due to its extremely good coating properties. here some specs on its 5w-30 http://www.rallysport.ca/lubricants/300V%20Power%20Racing%205W-30%208255%20%28GB%29.pdf if anyone has tried it, what do ya think about it

Shell rotella t 5w 40 is for all engines it has an sm api rating which our service manual says we can use in our trucks
Say what you want, but after about 20 years of using CD2 Oil Detergent I swear by the stuff!
The only caution I would give is that if you have a HIGH MILEAGE vehicle, or one that has had any oil leaks at all at any time I would not use it. Because the detergent in it works so well it can actually re-open old oil leaks.
Beyond that however I have PERSONALLY experienced it do amazing things with cleaning out the CRUD that builds up in the motor.
