Zoomzoom. I'm using the Belgium Castrol
5w40 in my BMW. In most countries (France,
Denmark,Finland, South Africa), this oil
is called a sythetic under the TXT Softec
name. It may be a mixture of Grp.3 and
Grp.5 basestock. I do know that if this oil
was developed to reduce sludge and wear in
sludge prone VW engines, just think how clean
it will keep a normal engine.
It does not meet the vw 503.01 spec and in Germany it is refered to as a hdrocracked oil. It should work great for 5-6k miles but will probably thin to a 30 weight anyway. GC is shear stable with no VII's and will last longer. This info is for the green GC, we don't know about the gold yet.

this is the oil that I am talking about:
Castrol Syntec 5w-40 - Specially formulated to meet the needs of BMW, Mercedes-Benz and Volkswagen - Offers full synthetic performance, engineered specifically to meet the Volkswagen engine warranty requirements, including testing in VW TDI® engines.
VW 502.00, 505.00
MB 229.1, MB 229.3
Our friend Mola's singing an interesting tune
Says BC comes from the Black Lagoon.
Well I for sure don't know about that
But keep this info under your hat.
In any conditions, hot or cold
This stuff is 'bout as good as Gold
So if Made in Belgium is what you see
You've got the brew known as BC
hm so it is fairly close to diesel oil..no wonder why VW and AOA want to use it in their sludge prone 1.8T's.
I was doing a TB and valve covers on my S4 in Audi dealership and we had to change the oil afterwards..and this was what they had.
I had GC in there with bearly 1K on it .
I liked the way my S4 felt with GC...It is definetly more "slugish" with BC and my oil temps are around 225 with it compared to 205-210 with GC..but I will live with it until late fall when GC will go in again...
I was toying with idea of trying to run Redline 5W-20 over the winter but I still have some concerns since this car is chipped and puts out 325HP over stock 250...I am also not sure how would my twin turbos react to 20wt viscosity?
