Hi everyone....I'm new to the forum and was wondering if anyone runs Amsoil 5w30 in their Mada along with the Ea oil filter? I just bought my 05 LE this past weekend and want to start things off on the right foot. Also, the LE has 63,000 miles on the clock.

Thanks in advance.

Amsoil is good stuff!!!! I think Scr38 and a few others are running it.

I was flipping through the owner's manual and it says that "Nissan recommends mineral based oil." Does this mean using synthetic oil is a waste of money?

What is everyone else using?

I've been using Mobil-1 from day 1..... I much prefer full synthetic.

I switched to Royal Purple synthetic and it really quieted the valvetrain down, and I don't have to change the oil as frequently. I'm using Amsoil in the trans and rears. All with good luck.

Since I bought my Mada used, I'm not sure what the previous owner used, is it safe to use a full synthetic motor oil or should I use a blend?

Use Full, I wouldn't waste my time or money on a blend.

I switched to Mobil1 from Amsoil. I now have less racket on startup - it seemed like after 3,000 miles or so on the Amsoil (with Amsoil filter) it got noisy. So I switched to Mobil1 and OEM filters, quieter now, even on longer intervals.

I use RP all around but for you with 63000 i would use 10w-30

Efharisto Scorpion. I already purchased the 5W30 Mobil 1 Extended Performance. I will see how this works.

Since the extended performance is good for 15k miles do you think it's safe to change the oil every 7.5k miles (I don't believe in going 15k between intervals)?

I would use what you have purchased as it is just fine. Everyone has there own preference as to which Synthetic they prefer, but IMO, I feel that if you use a reputable brand, you will be just fine. I have a different approach about the synthetic oil that I use. I actually switch brands each time I change my oil. There is a theory behind this method, but that isn't important at this point. The key to using the synthetic oil is to back it with the best possible oil filter you can. I prefer Mobil 1 or Purolator Pure 1, but that's me. That said, I have 65,000 miles on my Armada with no problems, and change my oil every 10,000 miles. I also own a 2003 Nissan Altima with the 2.5 four cylinder that currently has 174,000 miles on it, and it has always had an oil change every 10,000 miles. The Altima run like new, and it doesn't burn oil, never has had a leak, and the only thing in the engine compartment that has ever had to be repaired or replaced, was the crank angle sensor which was a factory recall. No doubt in my mind that synthetic oil is the only way to go. Good Luck!

I change my oil every 2500k and i use K&N oil filter even thou i use RP synthetic

I'm changing every 6000 miles with synthetic. Mobil 1 or Amsoil oil with a Mobil 1 filter or Purolator Pure 1...

im curious about your method...can you please explain...or point me in the right direction to get that info. also what brands do you switch between...and the grades?

I can't point you in a direction for the method, because it is my own! I use nothing but synthetic because it without a doubt is superior. What
I do is rotate between the brands of oil that I use, just as I rotate fuel injection cleaners. Why, well everyone makes the best oil or at least that is what they claim. How do I know they do, because they say they do! Well, lots of money is spent on marketing and since I have no means of actually testing the various oils, I really can't tell which is working the best. So my theory is this, rather than stick to one brand for the life of the car and really never know if that was the best oil for my engine, I vary the brands in hope that if one is not as good as the other, at least I have had a better one in there at some point. Same with fuel injection cleaners. As with oil, fuel injection cleaner is something that you really have no way of telling whether it is keeping the injectors clean or not, so if I stick to one brand for the life of my car and I end up having injector problems, well that is how I would find out that brand was no good. I figure if I try different products, perhaps one will be better than the other, and at least I will have benefited from that because at some point I would have used the best there is out there. If I truly new who's oil is the best or who's injection cleaner is best, then that is the brand I would stick with for the life of my vehicles, but I don't have the means to do the proper testing, so I stick with my rotation theory! As for brands of oil I use, well generally it will be Mobil 1, Royal Purple, Amsoil, and one that I am using for the first time, and that is called Matrix Lubricants. Matrix is a little known company in Texas that sells direct to the public. They manufacture their own oil and sell direct to the public, so there prices are great because they do very little advertising and they don't sell to a middleman. I just took a 900 mile trip with a fresh oil change with Matrix, and the Armada really seems to run smoothly with this oil. If you are curious about this company, there website is http://formulamx.com/. I don't think it is important what synthetic you use if you rotate, just stick with a brands you are comfortable with because again, nobody truly knows who makes the best synthetic oil. As for oil weight, I use strictly 5-W30. Oil filters are either K/N, Mobil 1, or Purolator Pure 1. I change my oil every 10,000 miles and I also have an Altima that now has 176,000 trouble free miles on it, with no oil or seal leaks, and I don't have to add oil in-between oil changes either. I guess my theory has worked well with this car, and time will tell how my 04" Armada will hold up.

I go back and forth between 5w30 Amsoil XL-7500, Mobil1, or Pennzoil Platinum. Backed up with Mobil1 or Purolator PureOne filters. Got 10000+ on the clock now.

I have run Mobil 1 full synthetic in my '08 Armada since my first oil change (now has 52K), until recently. I also ran Mobil 1 in my previous vehicle, '01 Nissan pathfinder, to 99K with no problems.

I began some research on oil quality after noticing some valve train noise at start-up on my Armada. I didn't like that the valve train took a second or so to get lubrication going at engine start-up...it indicated that the oil was migrating down from the top of the engine, which a quality synthetic should help protect against.

Tried Rotella full synthetic for a couple of changes, but no noticeable differences other that the cost...about $10 less per oil change... but still had the valve noise issue. Some have suggested that Rotella syn. is virtually the same oil as Mobil 1, with some soot control additives aimed at diesel fuel byproducts. Seemed like the same stuff to me...just cost less. :)

After some forum trolling and feedback from some folks that shared their used oil lab test results, I switched to Castrol Syntec German blend full synthetic. Most of what I have read suggests that this full syn. formulation is one of the best available in the US market today.

Here's what I know from using the oil, after two complete oil changes at 7500 mile intervals: 1) compared to Mobil 1, the oil comes out much cleaner after 7500 miles...you can actually still see through the oil stream as it flows out of the oil pan...nice dark red, but not fully opaque. By comparison, Mobil 1 at that interval is completely BLACK, burnt smelling stuff. I admit, I haven't researched what the difference in color means, but on the surface it looks like the oil is less contaminated..which seems like a good thing. 2) Valve train noise at start-up is gone...and the engine is noticeably quieter at idle. To me this indicates better adhesion/less migration, which is also good.

So, I endorse the German spec Syntec over Mobil 1 after years of using Mobil 1 exclusively...try it for a change cycle and see the difference for yourself.

Also, regarding change intervals, you may find this article of interest. http://neptune.spacebears.com/cars/stories/mobil1.html

That's great information Cayers71! As my above post has indicated, my 2003 Nissan Altima has now 178,000 miles on it, all with a 10,000 mile oil change interval with full synthetic oil. My wife told me the other day that I need to start looking at buying another car, and I just laughed at her. She drives it from time to time so I asked her what was wrong with the Altima and she said nothing really, it just has so many miles on it. I told it's just getting broken in! In my most recent oil change in the Altima and Armada, I put in Matrix Formula MX4 5w30 synthetic and these engines both seem to run real well, and no ticking at all on startup. It will be interesting to see what it looks like when I drain it.
