Mobil 1 0w40 Users?
 

Many Z owners use this oil?

Ran into a random Z driver in a parking lot yesterday and got to talking. He's been using MB1 0w-40 for over 30k+ miles and "swears by it."

Mentioned better flow at start up and protection during "hot drives" and a better anti-wear additive pkg. :driving: He also does the Oil Analysis thru Blackstone.

P.S. Been using MB1 5w-30 in mine :driving:

How does he know it has better flow during start up? Has he noticed a huge difference in temps from what Nissan tells us to use? And if yes what temps is he running? Better Anti-Wear additive pkg sounds like he is just talking out of his a**.

Well, it flows better because it's 0W

I wouldn't run 40 for any reason, car recommends 30, I use 30, no need to run thicker oil if I don't have to


And I think Mobil 1 is amazing, just not for this car

Stick with your 30 weight. The engine was designed for 30; 40 will be too thick for optimal operation. 40 probably won't do enough damage to worry about (more stress on the pump, &c), but why use the wrong stuff when the right stuff is readily available? If you were making long hauls in the desert, there might be an advantage to using 40; for everybody else, stick to the factory recommendations.

:iagree:

And if I cared to run Mobil 1 in my car, I'd run 0w30

Because that is how oil weights work?

From what's I've seen, the 0W oils work really well in the VQs. GC was a dream in mine.

For this guy specifically, M1 0W-40 is really thin for a 40W oil. It seems to run really well in the VQs, as they tend to like an oil that is slightly thicker at temp. UOAs look amazing.

I was a little skeptical about the "Extra Anti-Wear Protection," so I looked on the MB1 website and found that 0w-40 does in fact have just a little more Zinc/Phos additive, which is a common additive for reduced wear.

Also, it's spec'd for BMW & Mercedes (Normally calls for 5w-30; 0w-40 is rec. when using MB1) and GT-R etc...

As for "better flow," I think it's b/c it's a 0w weight oil.

p.s. He did say that his Oil Temps always ran high during the summer and that's why he changed over for a more "stable" oil at high temp

P.p.s I doubt he's on any forums... older guy

But he is still assuming. Especially on start up.

Well, let's remove the need to assume then!


Redline 5W-30: 62 cST @40C
Mobil 1 5W-30: 61.7 cST @40C
Amsoil 5W-30: 60.3 cST@ 40C
Mobil 1 0W-40: 65 cST @40C




Whether the higher viscosity in cold is helpful is a bigger questions, but most UOAs seem to indicate the VQs wear less with a 0W oil in them.

If I still had mine and was planning to keep it, I would have no qualms running GC or the M1 oil. I would not go back to a 5W oil though.

Ive been running 0w40 mobil 1 for allmost 80,000 miles with FI and my UOA's come back great.

I needed to get an oil change before I got my tune and was given the advise to use M1 0-40 by the tuner. I think I will continue to use it as temperature can be extremely hot here.

You just love to throw up all these facts huh? There is no reason to run that type of oil. Does he think Nissan the creators of the car do not know what they are doing.

I've used M1 0W40 since my second oil change. Only 12k miles on the car, but everything seems to be working well. Next change is going with a 25 row cooler though. I'm tired of running 200+ degrees down the highway on a cool day.

yes, how are supposed to make informed decisions with all these stupid facts getting in the way! :shakes head:

They absolutely know what they are doing--giving directions to the lowest common denominator to minimize their risk. 5W-30 is common and safe...but there are several other oils you might want to use for specific use cases.

Nissan recommended ester oil anyways...do you use that?

They do make things tough:rolleyes:

I've always used Castrol synthetic 5w-30. I'm boosted for 5 almost 6k miles and gonna do a UOA. I'll try Mobil synthetic 0w-40 n after 2 oil changes of using Mobil synthetic 0w-40 I'll do another UOA.

Define 200+? 205 210 220 all normal good temps. 270 280 290 okay your having a problem.

I use an oil with ester because Nissan says its a good idea. And its been proven to be effective. Running another a different weight oil has.not

Hop on BITOG and read for yourself.

According To a MB1 rep I spoke w/ @ sema, 0w40 has ester as part of its ingredient list.

I believe all M1 synthetic oils contain esters

It says it on their website now too
It's just not Ester "based"

I have m1 0w40. This is synthetic under the euro standard, not the same as the US standard.

This is GTR's factory fill.
Great UOA's are the quantitative proof.
Nissan "ester" oil is just normal non-syn oil with ester additive to quiet down the vvel. I remembered reading about poor UOA's in vq37 application.

If weight is an issue, "German Castro" 5w30 is excellent. Redline 5w30 is another good one.

But oil is like a voodoo topic, some feel better to just stick with what manufacturer says, others rely on UOA's, just do whatever you want.

If your oil change interval is not too long, exercise precaution on cold start, and normal driving takes up 99.9 percent of the miles on your odo, result of this debate won't matter too much I think.

The only German castrol I've been able to find stateside is the 0W-30

My mistake

No worries.


I've heard rumors that some folks have found a 5w-30 GC in the US....I guess we can hope.

i ran mobil1's 0W-40 awhile back and noticed the oil warmed up much quicker in the mornings. buuuuuut i also noticed i burned more of it everytime i checked my oil level which is about once every two weeks.

i went back to 5w-30 and ill stay with it. redline was great too but you HAVE to be religious about changing it every 3k miles. after that the oil looks like crap!

The Mobil 1 0w40 is their best oil. I wouldn't use any of the API certified (5w30) Mobil 1 oils in this engine because the low ZDDP and high iron levels often reported by Blackstone tests. If you want to stay the stock weight the Redline 5w30 is the best option.

Do I dare ask, what brand oil Z drivers use most? :ughdance:

This is is good to know. I assume you're still using Mobile1?

this is true but the oil cannot go past 3k miles before its toast. also its 3 times the price of the mobil1 5w-30 im running.

as far as performance i see ZERO difference. as far as protecting the engine....... i hope its doing its job.

200-210 on a cool day (50F) at 80mph on the highway. Any stop and go traffic (same temp) and I'm to 230-240 in a hurry. Warm day in summer and I'm lucky if the temps ever get below 230.

I wouldn't sweat 230 honestly. Oil viscosity is tested at 210 degrees. My feeling is modern synthetic oil should hold fine at 230.

I always wonder, do the 3.5 maxima, Altima and FX/M37 ever have this oil temp "problem"? I think the oil temp gauge is making us z guys a little too conscious (myself included)..

Having said all that, being a car lover, there's nothing wrong with preferring a cooler oil temp.

Yes they do, my old Maxima would burn up oil, so I assume the new one will too!


I'll be adding an oil cooler sooner than later

When I got my oil change at the dealership not to long ago they used m1 0w-40 .

To my knowledge, only the VHR motors really have a serious oil temp issue.

The heads generate a lot of heat on the valve train and the only coolant up there is the oil itself.

There's a steel-on-steel junction in the valve train that heats up bad. Look at any disassembly pics of our heads, you'll see where the steel has turned blue from the heat near that junction.

0w-40 from a dealership? Really? By your special request???

^ nope I didn't even ask honestly they offered m1 or Nissan Ester and Ester was going to cost like 40$ more so I went with m1 and service guy said he recommended m1 better then I noticed it was 0w-40
