City and highway driving, no makeup oil added mostly because the Nissan dip stick is so frustrating to deal with.

The aluminum is the only thing that jumps out at me, anything to be concerned with?

Appreciate any information and advice.

Nope, and your base number indicates you probably could have gone over 10,000 miles! I wouldn't be worried with aluminum, this engine sheds a few ppm from what Ive seen.

wierd report. seems very good for 7000 miles. aluminum is a bit high in the sense that it is the same as iron but when all metals are 6 and under I'd say awesome.

I'd love to see what 10000 looked like. most likely darn close to this one.

it's the WIX oil analysis kit from Amazon, not Blackstone Labs.

it is a little strange, iron didn't go up from a previous Blackstone sample with 5,500 miles.

yet aluminum went up, pistons? sorry to nitpick, just looking to learn.

The average ppm aluminum from the VQ engines are 5

Why are you running such a heavy oil? That motor is spec'd for 5w30, API SL.

Really? I'm not trying to start an argument....but there is virtually ZERO difference in viscosities between most 30 weights and M1 0w40. The difference is insignificant.

Any engine that specs for a weight would beg for M1 0w40 if it could talk.

That looks like a great match for your 3.5. I'd keep using that. thumbsup I've used Mobil 1 0W-40 in my Integra that specifies 5W-30 before and the UOA came back excellent. FWIW, that oil is only about 1 cSt thicker than the 10W-30 High Mileage oils I have been using in my Firebird.

Because it returns good UOAs?

False.

Mobil 1 5w30 has HTHS of 3.1, whereas the 0w40 is 3.8. That means the 5w30 is nearly 20% thinner in operation. That's not insignificant.

Go graph them on the Widman site if you don't believe me:
http://www.widman.biz/English/Calculators/Graph.html

By running the 0w40 you're robbing power & MPG, increasing oil pressure, and increasing heat. Until you can objectively prove that the 0w40 is necessary over the manufacturer spec'd 5w30, there is no reason to use it.

I didn't catch the 40 wt. Nissan is pretty picky about running the reccomended weights in their vehicles. I'd like to see a uoa with the 5w30. Might be even better.

He might be losing like 1/4 of a horsepower and 0.000002Mpg though really. While there is the potential for impact there I'm doubting it is even measurable.

Yes, he's likely increasing oil pressure. He may be increasing heat (depending on whether oil temps are thermostatically controlled or not), but there isn't really a reason NOT to use it either, as it is likely a better product (it may not be adding any actual benefit but that's an aside and we aren't equipped to measure that here) than what the car specifies.

OVERKILL, your points are well taken. But we have seen countless UOAs on here from VQ35 motors (DE, HR) that show it is perfectly happy to hum along on whatever 5w30 you put in it.

As it is, the whole "VQ37s destroy oil" myth seems be getting disproven around here too.

I think OP should try the 5w30 and see that his UOAs come back just as good if not better, but that's my opinion.
