mobile 1 oil... is it that bad?
 

ok so i have always used mobile 1 in my cars forever. however i just ran across a couple threads saying it wasnt good for our motors since it was non ester based oil.

1) why doesnt nissan mention this in the manual. it says use "synthetic oil".

2) my other question is, should i just finish off my 3000 miles with this oil and switch to redline or should i look to get this outta my car as soon as possible. i guess what im askin, is running one 3000 mile cycle on mobile 1 gonna do any damage or cause any more valvetrain noise?

Search more. Plenty of oil threads and differing opinions regarding Mobil 1 and ester based oils.

searching is what has led me to starting this thread. seems like some people swear it will ruin your motor, while some say it runs great on these 3.7's. im more comfused after searching than i was before. before i wouldnt have given mobile 1's credibility a second thought

thats the only thing nissan wants you to ever run in the GTR...so you know ive been using it for 3 years now... dont see why it would be different or worse for the Z

prior to the couple threads i saw on here, i have NEVER heard a bad word uttered about M1.

:icon18:

And you are going to be less confused after the various replies to this thread? The same people who posted on those other threads are gonna post here and give the same opinions. It's not like there was some consensus reached and nobody bothered to post it :)

tell me your secrets hidden underground wealth of forum knowledge!
:stirthepot:

there has to be some secret society of auto engineers hidden here somewhere to tell me wtf is goin on with this mystery mobile 1 issue that apperently only the nissan community has stumbled upon...

i just wanna make sure we arent making something outta nothing..

For what it's worth, I run Mobil 1 and car is doing fine. No way Mobil 1 is gonna "ruin" your engine. Also no reason to believe that Nissan's magic Ester oil is any better then a top tier synthetic.

I use Mobil 1 only listen to me.

There you go edub, the internet has spoken. :tup:

well when you put it like that.... :roflpuke2:

i knew the secret underground 370 knowledge would surface

:iagree:

I use it too, and I just stayed at a Holiday Inn Express :icon17:

I've used Mobil 1 in my cars based on the fact its the 'Official Motor Oil' of about 80% of racing... If it's good enough for them, it's good enough for me. :tup:


Hey I stayed in a Holiday Inn Express too recently... and woke up with a severe rash... :wtf2: What was your room number...?? :icon08:

:roflpuke2:

I stayed at a Holiday Inn Express during the EMCO Gears Classic and those rat bastages wouldn't let me drive in the race.

OP. The "importance" of oil is waaaaaay overplayed. I use Mobil 1 and have for awhile. The worst thing involved with oil is not changing it. And if I'm not mistaken, M1 does have esters in it. Also, do you really believe that Nissan makes their own oil? Let me answer that...NO.

For what its worth on the subject. I know of someone who has "religously" ran mobil 1 on their 350 (different beast i know) for over 160000. The only thing to break on that car was the passenger and driverside door handles....oh and 1 thermostat at 140,000. just a fyi.

my friend told me that castro gold is better than mobil 1..really makes me go hmmmm?? so which is better? lol

Is he Cuban? :)

lol no

That settles it then. just as i thought, haters on mobile 1 prolly just hate cuz of what the dealers or performance shops happen to be pushing that day

From what I read on the 350z boards, Mobil1's UOA results were less than spectacular. That may be a reason why it gets the bad rep.

Personally, I shy away from it, but I do use their filters.

If you really want to know have your oil sent out and tested.

I just got an oil change on my Z at the dealership and they used mobile 1, and it seems a bit more sluggish after. I asked my brother in law about it cause he know a lot about cars and racing, and he said the viscosity of the oil might be why. the computer might sense this. not sure if thats even remotely possible but next oil change im going to get nissan ester and see how see drives.

Mobil 1 is the most terribly awesome motor oil you could ever possibly not use in any engine but yours.

I would definitely not unrecommend avoiding not using it if you don't care about not keeping your engine from getting unruined or not.

I paid $100 for Ester oil. It's not required, but Nissan recommends you spend a lot of money for expensive oil because the car runs really hot.

I think most of us are fine with any brand name synthetic. How often do you even hear of engines blowing anymore? If you use any quality oil you will most likely have long life out of your engine.

Personally I stick to ester base ONLY because I drive the car infrequently so the extra cost doesn't really hurt me that much. If it was a DD I would use Castrol or Mobil 1.

Ester oil was a warranty requirement for the 2009 model-year Z That's where the persistent and erroneous ester-is-best thinking came from. In 2010, that requirement was dropped along with Nissan saying that they no longer required ester oils for the 2009 model year anymore.

Mobil 1 is fine. So is Castrol, Redline, etc etc...virtually every other quality synthetic oil.

All things being equal there is no way to feel the difference in oil while driving.

Either it's in your head or you've got some other issue.

:iagree::iagree:

BTW it's Mobil not Mobile :icon17:

/\ this. BUT the crappy UOAs were for Mobil1 5w30. I personally am running mobile 1 0w40 since it's a true synthetic (unlike their 5w30), has very good UOAs in general and the slightly heavier weight is good since this car sees track time on a semi regular basis.

Oh, and that nissan ester oil is a crock. The uoa's for that oil havent' been any better (and sometimes worse) than many other oils out there.

This is exactly why I typically run Castrol Syntec 0w30. The UOA's seem to be pretty good for my Z so far.

M1 0w40

:thumbup:

use wesson canola oil or ***-troglide

man a guy makes on quick mistake with some spelling and you guys have the time of your life with it haha.

GC 0w30 is good stuff too. My other choice were I not running Mobil1.

:tup:

I've been using Mobil 1 since my first oil change. If it's good enough for NASCAR motors, then it's good enough for my Z.(btw when I was told at the dealership that an oil change with Nissan ester oil was $125.00,I said to myself nfw will I pay that much for an oil change- it was a ploy to sell me the "extended warranty package" . That too was a nfw!

Not all motors are engineered the same, hence the variety of motoroil on the market.

Your nascar comment is borderline retarded. No offense if you are actually mentally handicapped. I love retards.

LOL I agree witht he above statement in reguards to engine design. New mustangs run 5-20 and z's are running 5-30 or 0-30 is good too. Just because it works great for american won't mean it will work for imports. I am considering getting my hands on some motul.

Also, when considering UOA's you really need to note at what mileage it was taken. Comparing one oil on a car at 1000 miles to another oil at 10,000 doesn't really tell you much about the oil.

mobil 1 0w40 is the only true synthetic from mobil and i have used it for 78,000 of the engines boosted life.
