For $10 more they will tell you the condition of your additive package.

I have benefitted a lot from what you guys post here, as I'm definitely less knowledgeable regarding maintenance, mechanics & automotive stuff. Thay said, it's my understanding that, at least, some "debris" (i.e. minerals, etc.) will circulate through our internal engine parts, but modern motors can take thay & much more.

I would be interested to see the results too.

It makes me want to do some analysis too, even though I use Castrol GTX 10W-30 and only have done one oil change, since most of us don't drive our sport cars in the winter.

Just a FYI, in Canada we use Fluid Life based out of Alberta and Ontario. Same tests different company.

I bet this wouldn't do much for a first oil change since it would probably be expected to haev tons of debris. I am gonna cut the oem filter open when I do the first oil change. I bought the magnetic filter cover and drain plug I hope they do their job!

Oil analysis
 

A shamless plug (Amsoil Dealer)! Doesn't Amsoil provide oil analysis as well? Have you conducted any oil analysis of 370Z's using Amsoil 0-30w?

I use Amsoil 0-30w in my former Z with good results.:tup:

I originally thought about going with an aftermarket oil, but after reading about the "magic" Nissan oil, I've been sticking with it. (Going on my 4th oil change now.)

After seeing these results, I'm second guessing.

Subscribed.

Perhaps we are concluding from the wrong direction.........Is it possible that the Nissan ester oil is actually "collecting" into its "solution" more of the contaminents that build up from engine wear & tear and heat than what other oils collect off the moving and extremely heated parts?? So in essence it may be doing a better job keeping the parts clean it comes into contact with...

One of its claims is that it removes surface contaminents better than other leading oils.

^^ I like the way you think!

^ me 2

i'll be switching soon from Nissan oil, I'll get a sample out of that (100% stock now) and switch to a different oil either Amsoil 0W30 or maybe Motul and then get another test after that.

The contaminants shown are traditionally interpreted to be a sign of excessive wear not superior detergency LOL

But the sample is only as strong as the oil's ability to remove the contaminants, so one motor using a better "detergent" oil appear to have more wear, versus a not-so-good "detergent" oil appearing to have better wear because it isn't removing enough. Too tough to be positive either way. This is a moot point now IMO.

Are you in politics???:ughdance::ughdance:

No, he just isn't ready to jump to any conclusions, I'd say.

Well, it does contain abrasives afterall. Nano-Carbon Particles!
