:wtf Happened to Mobil 1 5W-30 synthetic motor oil ?

The current Mobil 1 5W-30 oil that is API SM / ILSAC GF-4 rated.
It is only ACEA performance rating of A1 :thumbsdow

The last batch that I have of Mobil 1 5W-30 that was API SL/ILSAC GF-3 rated.
Bottle dated March 3, '03.
Has an ACEA performance rating of A5.


So Mobil 1 5W-30 oil has less performance protection now for your vehicles.

See for yourself:
http://www.mobil1.com/USA-English/Lubes/PDS/GLXXENPVLMOMobil1_5W-30.asp

Note:
Mobil 1 10W-30 that is API SM /ILSAC GF-4 rated, still meets ACEA A5 performance rating.
&
Mobil 1 EP 5W-30 that is API SM / ILSAC GF-4 rated, meets ACEA A5 performance rating.
(But Mobil 1 EP oil is not available in Canada.)


Makes me glad that I am using Made in Germany - Castrol Syntec 0W-30 oil that is ACEA performance rating of A3 (A3 is > than A5, when talking all out performance. A5 keeps fuel economy/energy conserving in mind) :D
But the additives only meet API SL (SM limits some additives to a reduced level) & no energy conserving donut (it is too thick of an oil) lol

i switched to amsoil not too long ago. i kept hearing bad things from a few people about mobil 1 regarding it's performance.

No way I'm letting it go for 10k. I still change it every 3-3.5k.

Mike, you keep posting this stuff, but what does it mean? Seriously, dumb it down for us people who don't know/don't care to read up on it. I use Mobil 1 5w30 and change it now around 5k. So, if that's what I'm doing, and Mobil 1 is going to cause my engine to turn into a nuclear warhead, what should I be using (aside from Germany made Castrol, which I don't know if I can even get around here/don't care to/don't feel like finding out). So, what other oil should I be using (US made, readily available at any auto parts store) so that I can prevent armageddon?

Just informing user's of Mobil 1 5W-30, that the current version is not the same as the old version.

ACEA (Association of European Automobile Manufacturers) is an European performance/minimum quality level rating standards for oil.

There are 3 standards, that we care about for gasoline engines:

ACEA A1/B1:
"Oil intended for use in gasoline and car + light van diesel engines specifically designed to be capable of using low friction low viscosity oils with a High temperature / High shear rate viscosity of 2.6 to 3.5 mPas.s.
These oils may be unsuitable for use in some engines.
Consult owner manual or handbook if in doubt."

ACEA A5/B5:
"Stable, stay-in-grade oil intended for use at extended drain intervals in high performance gasoline and car + light van diesel engines designed to be capable of using low friction low viscosity oils with a High temperature / High shear rate viscosity of 2.9 to 3.5 mPa.s.
These oils may be unsuitable for use in some engines.
Consult owner manual or handbook if in doubt."

ACEA A3/B3:
"Stable, stay-in-grade oil intended for use in high performance gasoline and car + light van diesel engines and/or for extended drain intervals where specified by the engine manufacturer, and/or for year-round use of low viscosity oils, and/or for severe operating conditions as defined by the engine manufacturer."

ACEA A3/B4:
"Stable, stay-in-grade oil intended for use in high performance gasoline and direct injection diesel engines, but also suitable for applications described under A3/B3."

ACEA EUROPEAN OIL SEQUENCES booklet - 2004 Revision 1 - SERVICE FILL OILS FOR
GASOLINE ENGINES
LIGHT DUTY DIESEL ENGINES
ENGINES WITH AFTER TREATMENT DEVICES and
HEAVY DUTY DIESEL ENGINES (http://www.acea.be/ASB20/axidownloads20s.nsf/Category0ACEA/A3164D2EBB7E1840C125708C004EE21F/$File/ACEA2004_rev%20Sep05.pdf)


Will your engine be killed using Mobil 1 5W-30?
Very unlikely, unless you put your engine to the extreme.
Then there are better oils to pick.

It is now not as good for:
extended oil change intervals,
higher oil temp oil conditions,
Turbo'd or super-charged engines,
track days.

Since it is no longer meeting ACEA A5 rating, but now ACEA A1 means with time:
the oil will shear more (thin out with use),
& more oil comsumption from burning up / evaporation.


My sugguestion, if you like to stick with Mobil 1 is:
Pass on the Mobil 1 5W-30 oil,
& use Mobil 1 Extended Performance 5W-30 oil (http://www.mobil1.com/USA-English/MotorOil/Oils/Mobil_1_Extended_Performance_5W-30.aspx) instead.

The "new" Pennzoil Platinum (http://www.pennzoilplatinum.com) EOP based synthetic oil also sounds interesting.


If your interested in (made in Germany) Castrol Syntec 0W-30 oil:
Look for it in:
in US at larger AutoZone stores.
in Canada at Walmart, Canadian Tire, or PartSource stores.


Bottom line:
IMO, the current Mobil 1 5W-30 is not as good (in performance) as a buy for your dollar vs in the past.
Past on the Mobil 1 5W-30 oil & get Mobil 1 Extended Performance 5W-30 oil instead.

PS: Mobil 1 5W-30 is still better than almost any dino motor oil.

So, Mike, if I can find Castrol Syntec Germen blend, how much more would I be looking at spending? Are there any negative effects of using 0w30 all year round?

It is not a "blend".
(Made in Germany) Castrol Syntec 0W-30 is full synthetic motor oil.
Here locally: it cost same or little less than Mobil 1 oil.
I am guessing in the US regularly around $5-6 per US quart.
It only comes in the 1 US Quart sizes, no big jugs.
Make sure it says on the back label:
Made in Germany
&
ACEA A3 rated.

(There is a possiblity of some old pre-2002 US made "winter" Castrol Syntec 0W-30 around. DON'T BUY THAT!)

Yes, there is some negatives using Castrol Syntec 0W-30 year around.
I find a little lower gas mileage (1-2 mpg) using it (hence the not getting the "Energy Conserving donut rating"); as it is almost a 40-weight oil when hot.
& it is pretty thick when cold, almost like Mobil 1 10W-30 at 0F range.
But it is cold crank start rated to -40C/F (0W-x must meet cold crank rating to -35C/-31F).
I use it all year long, so far from -17F to 95F range.
It seems to actually like it in the hot weather better for gas mileage.

So the only adverse affect would be lower gas mileage?

Yes.

Oh, maybe a little less power when the oil is cold.
I never noticed any.
I almost always baby my car until it is up to normal operting temps, before getting on the gas.
(Some small engine car owners, like Honda Civics say it rev's slower. But they are comparing it to a thin 5W-20 synthetic blend/synthetic oil.)

PS: I heard from a Ecotec GA owner...

That (Made in Germany) Castrol Syntec 0W-30 oil smoothed out/made quieter his engine; compared to Mobil 1 oil.


Next oil change on my Mom's Sunfire GT 2.4L engine (late spring) will get Castrol Syntec 0W-30 oil.
(Currently running on the last of my Mobil 1 5W-30, ACEA A5 rated oil.)

If you can find it try out Royal Purple.

I've heard great things about Royal Purple, but 2 or 3 years ago someone created a thread about it. They said that back in the day it was good stuff, but the company was going under, or something and sold it to someone else. They basically said that the forumlation wasn't the same (or they didn't know whether it was or not)... Anywho, that was a few years ago and that's the jist of it.

Probably why it's impossible to find it nowadays.

The Pepboys in my area always has 5w-30 and 10w-30 Royal Purple in large stock. I think Pepboys is the only one that carries it in store now. I've never found it in Advanced Auto Parts or Auto Zone, just like you can't get German Castrol in any other place other then Auto Zone. I personally use Royal Purple 5w-30.
