Just went to Petronas, they didn't print the logo but it is written instead :

I reckon the Mobil Super 3000 XE 5W30 is a newer product against Mobil 1 New Life 0W40.

http://www.mobil.com/UK-English/Lubes/PDS/...0_XE_5W-30.aspx

Super 3000 is a low ash engine oil (of 0.8% sulfated ash ) formulated for newer cars fitted with emission after-treatment systems. It's not meant for older engines , say pre-2000 , that comes without emission after-treatment systems.

Whereas Mobil 1 New Life 0W40 is an older formulation (having a higher sulfated ash content of 1.3%) meant for older engines .

http://www.mobil.com/UK-English/Lubes/PDS/...Life_0W-40.aspx

It's not meant for newer engines with the latest emission after-treatment systems.

Thus, I believe Super 3000 is not sub par against New Life .

Maybe somebody can shed some light on their commencement dates of formulation/manufacturing ??

look.
my understanding of mobil product line up is that mobil 1 is their top of the line, the best.
http://www.mobil.co.uk/UK-English-LCW/care...s_products.aspx

the fact that mobil have their 3000 products having API SM with lesser data sheet details compared to mobil 1 with API SN having more thorough data sheet published, is enough of an indication to avoid nit picking ash/phosphorous details.

either way BOTH are NOT under API licensing as i've mentioned which are either lapsed or just haven't license (new product, maybe?) yet which i quote again:


for all i know the 3000 could be just meant for low ash, but having a shittier additive/base stock, where else the mobil 1 new life is a new blend/formulation, having good additive package and base stock that's AIMED FOR older car to make them LIKE NEW (hence the damn product name, don't ask me on why ash or phosphorous would improve an engine, please ask mobil instead)

if you're THAT ticked off on the SAPS issue, by all means go with something like http://www.mobil.co.uk/UK-English-LCW/care...il-1-0w20.aspx#
which is 1) low SAPS 2) mobil 1 3) actually showing up on API certification.
personally, NEWER products and still looking back at API SM is NOTHING NEW to me.

You completely miss the point !

The technical point !

first off, let me clarify this as annoying as it may be after a few replies already and you just have to have quoted replies where i have to do a lot of manual work:
I am not a lubricant engineer, merely an enthusiast who goes through length that most people would think i am crazy for doing so.
With that said, i believe every human being, including lubricant engineers would make mistakes and as i have made disclaimers NUMEROUS a times in my previous replies which you've blatantly ignored while continued to nitpick me on SAPS. (sulphated ash, phosphorous sulphur, just in case.)

Last clarification:
http://www.gf-5.com/uploads/File/API%20SN%20Discussion.pdf
(and as linked on first page of this thread)
http://www.gf-5.com/uploads/File/ILSAC_GF-...22-09_final.pdf
http://www.gf-5.com/uploads/File/Final-GF5...ent-1-23-08.pdf
only sulphur and phosphorous requirements, i don't see ash in this.
if you have further documentation for ash, by all means please provide them

summary:

Phosphorus	0.08 or 0.06
Sulphur	0.6 or 0.5

again, the oil parameters i see from 3000 are lacking compared to mobil 1.
not to mention, i cannot find NEITHER being certified on API.
heck, API SN itself doesn't have low SAPS requirement, only SN with resource conserving and/or ILSAC GF-5 does.

like i've replied, whatever purpose or categories mobil1 intended them from, it's best to clarify with mobil themselves more so when they have such confusing line up (it sure is giving you one heck of a tough time seeking so much clarification)

from the top of my head i've yet to recall modern EO having separation between flat tappet/roller rocker and so on. Perhaps i'm spoiled with my API standardization/going with reputable boutique brands that don't give me that much of a headache in choosing what oil to get from them.



Like i've mentioned, i'm not anal over low SAPS as posted above documents, if i am going for SN + ILSAC GF5 + resource conserving, i don't know, maybe because i ALREADY HAVE LOW SAPS.
but of course sure, huge blunder by lubricant engineer. (which i'm not btw, not sure how i am perceived as such, but ok.)


i quote myself again:

http://english.stackexchange.com/questions...-for-all-i-know

until mobil1 gives me more info such as more thorough data sheet, MSDS, a VOA and/or UOA, i am answering based on what i have.

so here is what i know:
mobil 1 > mobil 3000 as a general product lineup
info for mobil 1 is more thorough than mobil 3000
majority of mobil 1 products are indeed API certified as opposed to a lesser amount on the 3000

and just so you know, even FULLY SYNTHETICS, there's THREE groups of base stocks. please wiki them if you wish to know more (or heck read the first page already FFS)


now if you're still dissatisfied with my reply, by ALL means, please contact mobil directly to seek further clarification: http://www.mobil.co.uk/UK-English-LCW/cont...?CountryCode=UK
thank you.
if you're a HUGE fan of mobil 3000 over mobil 1, by ALL means, please use mobil 3000 instead.

my last and final input on this matter:
- i personally will never choose either mobil products
- if i am FORCED to choose one, which is the lesser of evils in my case, i would still stick by mobil 1.

unless you have anything new to share, i will no longer reply to you any further pertaining this matter and/or this 2 particular product.

thanks and have a nice day

you may be interested in this and see if you regret in mobil 1 or not because me as a lubricant engineer (lol) made a bad recommendation

*facepalm*

Wait till next oil change.so far so good hehe

hi sifu,
im newbie (just 'escape' from service center) and start learning about engine oil
a shop recommend me ELF fully syn 5w40 (im actually looking for fully syn 5w30). Is this good enough for normal driving habit?

Peace

Sorry for being technical and subjective in interpretation.

Good day .

Both oils are suitable for cars with emission after-treatment systems.

For normal driving , of course they are good.

5W30 is supposedly good for fuel economy.

Do take note 5W40 offers better engine protection in terms of viscosity.

in modern engine oil, no.

please read first page, and or my UOA samples.

In the absence of further data from ELF, I would make reference to certain oils from Mobil fully synthetic range.

A typical operating viscosity of a 5W40 estimates at about 16.8 cSt against 5W30's typical operating viscosity of 13.1 cSt .

IIRC 5W40 probably offers higher HT/HS viscosity than 5W30.

Thus a 5W40 offers better engine protection than a 5W30 , in terms of viscosity. Other oil parameters such as additive type and

quantity etc being disregarded for this comparison.


Note : HT/HS means High Temperature High Shear viscosity.

look at data sheets (VI, HTHS etc) and compare before making assumptions.

info on first page.

do take note, the HTHS difference between xw30 and xw40 in modern EO is very minimal.

https://mobiloil.com/en/motor-oils/mobil-1/mobil-1

HTHS Viscosity, mPa•s @ 150ºC (ASTM D4683) of various viscosity grades

Mobil 1 fully syn oil API SN :-

a) 5W-20 = 2.75 ;

b) 5W-30 = 3.10 ;

c) 10W-30 = 3.00 ;

d) 0W -40 = 3.80 ;

e) 5W-50 = 4.40 ; and

f) 15W-50 = 4.50

I attach PetroCanada data sheet table for public reference here.
Do take note the high flash point and low pour point that most mainstream EO can't compete.

thanks a lot for the input
besides the 5w30 or 5w40, is ELF good as in additive etc?

refer the image chemistry101 sent.

unless you're active in motorsports or have a tendency to red line your engine a lot, and actually overheating, the difference is still negligible.

or, refer my UOA which i've had multiple track days and constant red lining.
not the best wear report around, and the OCI was a little too long considering my usage, however it's still within acceptable range.

Yeah I already know that and it wasn't what I was getting at. What I'm saying is that there are popular products like UMW pennzoil, Mobil 3000 without official API certification or logos on their products but are labelled as SM/SN anyway.
