It's Castrol SLX 0w30 that is found off-the-shelf at random Autozone stores. In the back it will say that it's made in Germany. The label in the front is green instead of red. Not to be confused with the indentical red label 0w30 made in the States. Another tell tale sign is the green oil instead of the usuall brownish color.


It's suppose to be real good stuff and unlike the current Castrol synthetic it's not made from Group III dino oil.

specs:
Color: Green
Pour Point: -61*C
Flash Point: 238*C
Viscosity @ 40*C: 68.5
Viscosity @ 100*C: 12.1
Viscosity @ 150*C: 5.7
HTHS: 3.6
Cold Cranking Vis @ -30*C: 3200
TBN: 10.6
VI: 179

Any hoot, keep an eye out and do post if you come across it. It was first spotted in Canada and there has been some report that it has made it's way in the Mid West. So far all the local shops in Cali still carry the red label 0w30. I'm hoping it makes its way down here.

correct me if im wrong but wouldnt this be the same thing as buying 30W racing oil?

Want2race

someone in GA bought 20 cases of that at a police auction a while back.. I dont think its anything great!

Raymund

Nope, hence it has 0W rating before the 30.

This oil pours at -61C and At 40C, it has a viscosity rating of 68.5cst earning it a 0Wxx

straight 30 weight must only be within the viscosity of 9.30-12.49cst (centistoke) at 100C to qualify as a 30W

.RJ

what would be the benefit of this over regular syntec 5w30?

Raymund

LOL.. it's nothing great yet it was being auctioned in 20 case bulks.

Raymund

In general, 0W30 should flow better than a 5W30 during start-ups and yet provide the same oil film thickness at high temp. But, it all depends on a case by case basis. This German Castrol is actually thicker at 100C than Mobil 1s 10W30 oil. and will out flow it during colder climates. So, as it seems, this oil should provide better protection than M1s 10W30 at both end of the spectrum.

20 cases were stolen therefor 20 cases are sold at once...

ok i have a question.

Take 5W30 oil. The first number refers to the HOT oil viscosity and the second refers to the cold viscosity, or is it the other way around. I would think that hot oil would be thinner than cold oil...

.RJ

is 0W30 going to be too thin for high-rpm use?

I use honda 5w30 on track... no problems at all.

You have it backwards read Raymund Post. Multi viscosity Oil is formulated so that its thiner at ambient temp and thickens as it warms up. It is pretty weird.

RJ they both end up at 30 so as long as you warm your car up you should be ok.

Thats some crazy chit. Defying the laws of physics...

it pours at -61c deg. ****. when will california weather get anywhere near it for us to require a 0W-xx? NEVER. 5-30 fine,
i use 10-30 no problem with cold starts.

0w30 and 5w30 will flow the same when warmed up. the 0w or 5w is the flow characteristics 0 degrees F and the 30 is the flow characteristics at 212 deg. F.

Not really - viscous fluid LSD's work in the same way, only much exagerated.

There's a difference between defying physics and manipulating it.

One of my friends built a pretty interesting ITR motor a couple of years ago with NEO 0w 5 synthetic and has continued to use it since.

He swears by it as well as some others I know. I know JUN USA uses it in there race motors as well.
