Mobil 1 0w-40 or 5w-40

[meboice]

...a 10W40 is heavier than a 5W40? Although my question is general, I cannot help but think that the thickness of one similar grade oil isn't necessarily the same as another...?

[cmosentine]

Best oil I have seen for the 2.0t that had little oil consumptions and came out clean every 5000 KM was Lubro Moly... http://www.germanautoparts.com/Volks.../Engine/513/12 FOR FSI and http://www.germanautoparts.com/Volks.../Engine/513/13 FOR TSI take your pick by far one of the best oils out there and test proven in extreme hot and cold weather to have little oil consumption at my shop.

I second LM, but any 502 oil will work. You can get it at NAPA here in Michigan, but it goes by the name Liqui-Moly. But I caution that there are several types of LM, but only one is fully synthetic. They also changed the fully synthetic to 0w-40 (from 5w-40). When I first purchased my 08 WE, I used M1 0w-40. I found I was using about 1/2 quart per 5000 miles. LM cut that down to about 1/4 quart per 5000 miles.

[gmikel]

Haha, we're not open overnight.

Can't you get anything right?

so you work 3 to 11 so what

[meboice]

I've been using M1 5W40 TDT for 5 years and I change the oil approximately every 3,000 miles. I've never had to top off the oil...Though I find that this car is rare in this regard. ...but, 3,000 miles doesn't really give the oil a chance to burn-off. We were very careful about engine break-in too.

Depends on the temp. At operating temp they are the same. This temp is where the visc is measured for the labeled grade, in this case a 40 weight, the visc at +100c is a range from 12.5cSt to near 15cSt. The W-rating is simply a cold cranking test at progressively colder temps (-20f, -25f, etc) and is separately determined.

http://www.widman.biz/English/Calculators/Graph.html

A 5w-40 is thinner at all temps below +100c than a 10w-40 or 15w-40. That doesn't mean a 5w-40 is thinner than a 10w-30 though. Every visc and every product needs to be analyzed specifically to compare their viscs.



As you can see, 5w-40 isn't drastically better than a 10w-40 in cold, esp when compared to a 5w-30.

keep useing it, you're fine. it's no where near as complicated as apeshirt makes it.

[Apexxx]

Too complicated for some people.

Motor oil threads on Vortex make me giggle. They always start off with someone asking an innocent question (In this case, Mobil 1 0w-40 or 5w-40), and devolve into arguments similar to gay vs. straight, Coke vs. Pepsi, carnivore vs. vegan, or 1911 vs. Glock.

Great fun for those of us that simply change our oil at the specified interval with VW 502 spec oil.

Please, by all means, carry on...

Well, it is a technical forum afterall.

[gmikel]

use an approved earl and all will be fine.

[Apexxx]

yeah, because vag never ever had an oil related issue.

no way either could there ever be a better oil than oem oil.

see, if you have zero clue, oem oil is a good way to go.

the rest of us are here for more information, and most everyone has heard about VW 502, believe it or not. if that's all you have to offer, you should maybe find a new hobby, like beanie babies. it suits your comprehension level.

[gmikel]

you would be lost if you could not tell us how smart you think you are and how stupid we are. somebody needs a new hobby for sure.

vag had an oil sludge problem in the longitudinal 1.8t. however they addressed it with the larger oil filter ( not for more filtration but rather to increase capacity) and requiring synthetic oil. not perfect for sure, but i've got an 03 passat 1.8 with 150000 mikes on it without any problems using whats recommended. i've got a couple of friends with well over 240000 miles and no problems. no uoa's either, just regular service.

Point proven...

[Apexxx]

The best part, 'changing at the specified interval'. Uhh, is that 10k or 5k, like when the 2.0t was first introduced, before inclusive service? Are we going to take into account 'severe operating conditions' or not?

Wait, maybe just get a UOA? Oh, I did.

I see a lot of gums flapping, nothing but frothy poop coming out.

2.0T's with VW502.00 oil have always been specified at 10k OCI.

VW502.00 is the severe operating conditions oil.

[Apexxx]

Umm, nope. 1st change at 5k prior to inclusive service.

[BsickPassat]

Umm, nope. 1st change at 5k prior to inclusive service.

Vw = 5k, then another 5k, and then every 10k thereafter
Audi = 5k, then every 10k thereafter

from the 2008 manual, prior to the CareFREE service:



... after the initial oil change(s)... 10k OCI's, just as I stated earlier.

VW502.00 is the severe operating conditions oil.

[BsickPassat]

if it was 5k oci's, then the service intervals would be 5k, 10k, 15k, etc

[Apexxx]

And your point is....?

[edyvw]

OMG!
Ok, in a country where speed limit is in some extreme cases 75 miles per hour there are people so obsessed with oils that my question is: do you have a life?
This obsession would be justifiable in Germany where cars can use their fullpotential and where you need best tires, best brakes and best oils.
So, to make life easier: Use Castrol 0W30 or M1 0W40.
Why using Rotella? Why usinf TDT? What is a point? Price? UOA?
If VW says that M1 0W40 is good for the car or GC or whatever oil meets 502.00, why reinventing the wheel?

[gmikel]

[Apexxx]

I have no objections to 502 oil, but we do have better alternatives.

502 fanbois should bear in mind how poorly it faired in:

1.8t



3.2 VR6




2.0 FSI




4.2 FSI




and 3.0 AVK.




I guess it's easier to theorize than to actually examine facts.

Otherwise, just follow the manual and don't think for yourself.

[edyvw]

I do not have a clue what you talking about!
I used in my 1.8T GC all the time and engine was clean like new!!!

[Apexxx]

Ok, stick your head in the sand.

how many miles on the engine and was the oil even changed. their is nothing to validate that oil was a problem, more likely it was a lack of timely maintainance.

[Apexxx]

So, you're saying that, without a full explanation, you're lost.

Sorry, some people here will get left behind.

[edyvw]

Ok, stick your head in the sand.

I am coming from Europe. In Europe all 5W40 or 5W30 or 0W30 meet 502.00.
For sludge problems I heard first time when i moved to the US! My friend actually screwed up his A4 bcs he was thinking that $19.99 oil changes are OK with these cars. In EU $19,99 oil change does not exists! You go with synthetics and you pay for them, trust me. So there was no sludge issues!
Now, I always used GC, changed oil every 7,000 miles, and engine was like a brend new inside!
Now, you are showing us pictures that means what?
Oil in those engines could be any oil, it could be 502.00 that was changed like every 40,000 miles.
Means nothing!
I have never heard from friends who owned 1.8T and used 502.00 that they had ANY problems!

[Apexxx]

Europe has different, more highly refined, fuels, for starters.

GC is actually a 503.01 oil, which is a different beast. It's the long-life spec, that exceeds 502.

If you range over to the FSI Forums, you'll see failure after failure on spec oil. People using HD or high zink oils had essentially no failures.

Blaming owner neglect on 1.8t sludge, and "all" the other instances I cited is outright arrogant.

Remember, VAG speced a larger capacity filter to solve the sludging oil problem, which has nothing to do with oil quality issues. People who did 5k changes over the "official" 10k changes were well-served. You can't BS me, I was there in 2002 when Audi went to 10k. I had a new B6 1.8t, so **** it.

VAG also updated the 502 spec in 2004, with sludge resistance as a priority.



Welcome to reality.

If you're happy with your fanboi oil, that's ~totally awesome~ (pun intended)

[Apexxx]

Don't forget people, spec oil is the ONLY way to go...



Surely an error. Dozens of samples must be wrong.

Everyone wants to play with fire, but no one likes getting burned.

[gmikel]

whatever

[edyvw]

Well, there is first problem of the fact that Synthetic oils in the US are by far Group III oils (except few like GC). They are mainly lower quality than European oils (which you said are not having bragging rights).
Also, not all European countries have low sulphur fuels. Go to Ukraine, Serbia, Macedonia, Bulgaria etc and you will see content of sulphur in the fuels.
I was changing GC every 7,000 not 5,000 as VW said, and no issues at all.
I agree with you that SOME 502.00 oils could be a problem, but by far, big majority is not!

[Apexxx]

BZZT, they're all Gruppe III now.

PAO base oil?

What is this, 2003?
