Hi there,

which one of these three oil´s should I use for 2001 GTI 1.8T:?

http://oil-center.de/shopupdate/magento/...30-1-liter.html

http://oil-center.de/shopupdate/magento/index.php/sae/sae-0w-40/shell-helix-ultra-0w-40-1-liter.html

http://www.fahrzeugoel24.de/de/shell-helix-ultra-5w40-1-liter.html

I live in germany and usually run an oci of 6000 miles. I found that the engine runs quiter with the Shell oil compared to Mobil 1 0W40. So I switched first to the 0W40 grade and current i am running the 5W40 grade

And then I came across this forum and startet reading about the GC 0W30 producing great results in almost any engine.

So now I cant make up my mind which one I should use next. To be honest I would love to give the GC a try but am kinda worried because my engine has around 100k on it and has an ECU upgrade, mufflersystem, fmic and more of that good stuff to produce more power.

Always been on sythetics (first 0W30 standard VW Oil, 0W40 Mobil1, 5W50 Mobil 1, 0W-40 Shell Helix Ultra and now the first fill 5W-40 Shell Helix Ultra)...

Is GC "Turbo safe"? It would be great if someone could post UOA´s over the mentioned oils,cant seem to find many in the search:)

Thanks much in advance for any advice:)

stormy,
Any of the synthetics you listed should be excellent choices for your car. I prefer a 5w40 or 0w40 for a turbocharged car. Mobil 1 0w40 is a very popular choice for hopped-up European vehicles over here - but honestly I would use whatever 0w40 or 5w40 synthetic that's the least expensive. I've seen how much oil costs over there!

I'm no longer a fan of GC 0W-30 due to it's lowish 167 VI.
For example M1 0W-40 is lighter at all start-up temp's as high as 25C. It's 12% lighter at 0C.

Of the the 3 oil choices you've provided, Shell Helix 0W-40 would likely be my first choice although I'd like to see the info on a PDS first.
 
Shell Helix Ultra 0W40:

Cost´s about 7€ in the internetshop I always buy my oil at...

Shell Helix Ultra 5W40:
http://www.epc.shell.com/documentRetrieve.asp?documentId=64146022

around 6,7€ on the net:)

Castrol Professional Longtec 0W30 (think its the GC everybody talks about here?)

http://datasheets.bp.com/bpglis/FusionPDS.nsf/0/2836C2ED45EE0795802577ED00480CAF/$file/BPXE-85KPNL_0.pdf

Somewhere around 8,8€

Pricing always 1 Liter (a little more than a quart)

Dont want to run the M1 0W40 anymore since they changed the formula for one:

old:

New:

http://src.discounto.de/pics/product/30549/48233_5-Liter-Mobil-1-New-Life-0W-40-30549_xxl.jpg

And for two always had lifter tick and timing cain "rattle" at cold start in the winter with Mobil 1. That left after about 4k with the 0W40 Helix Ultra (not one tick ore rattle at all, plus the engine ran smoother than ever(not so rough as with mobil 1 )
smile.gif


So after the second intervall of the 0W40 I thought I´d give the 5W40 grad a chance...

After looking at the pdf´s myself i figure the 5W40 grade from Shell is out (not much differnece to CG at 100cst) ..Eventhough it has better specs (HTHS at 3,7 for both Shell grades) like Ferrari and the VW 503.01.

So basicly 0W40 Shell Helix or CG 0W-30?

2 more questions, what does "stout" mean? (been living in germany for a while lol) and why is a low VI a quality mesure? Always thought because the spread 0 to 30 is smaller than lets say 0 to 40 the first would have less VI thus being more "stable"?

Thanks again

Here are the specs. Looks pretty good, about on-par with M1 0w40 (slightly lower HTHS).


KV @ 40 = 74.5
KV @ 100 = 13.5
VI = 187
Flash = 222 C
Pour = -35 C
HTHS = 3.68

API SM/CF
ACEA A3/B3/B4
VW 502/505
MB 229.5
BMW LL-01

Stormy, thanks for posting the Helix 0W-40 and 5W-40 PDS info.
Actually the spec' of the two grades are very close as far as their above none extreme cold performance is concerned.
They both have the same 3.68cP HTHS vis' and their VIs are 187 and 180 respectively.
So yes I would definitely choose both over GC giving a slight perferance to the 0W-40 grade. It's too bad we can't, IFAIK, get those European Helix grades hear in NA as they look to be a good alternative to M1 0W-40.
 
Sounds like the Shell 0W-40 is your oil.
Relatively inexpensive and quiet in your application.
You could try the 5W-40, if you want to save a little cash, and it might do well also.
Still, if the 0W-40 cleared up your lifter tick, and the price is at the lower end, why not just use it?
Why pay more for Castrol, which might not be any better, or might even be worse?
I've had GC in most of my cars at one time or another, and I've always found it to be smooth and quiet.
However, if Shell Helix Ultra 0W-40 were readily available here (I'm pretty sure you could get it, at some insane price, since you can get pretty much anything here), I'd try it in the Forester.
I think you've found your oil for your car as you use it.
 
Shell Helix 0w40 can be shipped to the US, but why bother when there's stuff like M1 0w40 that's equivalent or betteR?

More robust, stronger, able to withstand harsher conditions.

Or like bier - on one hand you have fizzy, light lagers like Kronenbourg. On the other hand you have heavier, richer, more flavorful brews like porter - those are more robust.

Thanks for the explenation for stout

No thing about the pds infos

I think I´ll go with the Shell Helix Ultra 0W40 for the next change (still have a liter in the trunk and a liter of the 5W40 at home)so I can use the "old" stuff up
smile.gif
...and just stick with it
smile.gif


As far as I can tell (ignoring the lifter tick I had on startup with the M1 0W40)

Thanks for everythin so far
smile.gif


Any more info is welcome

Got one more question:

Just read this article on bitog (especialy the conclusion)...

http://www.bobistheoilguy.com/effects-of-shearing/

...and was wondering if that means the GC would have higher stability against shearing and heat compared to the Shell Helix Ultra?

Thus meaning less bearing wear for instance?

Found a pds from GC that said it had GF-3 SL

No because even if you have slightly more percentage viscosity loss with the higher VI Shell Helix, since you're dealing will a 40wt oil vs a 30wt it will still likely be heavier at operating temp's.
Another point is that GC 0W-30 doesn't meet the Porsche A40 list and I believe Shell Helix does.
