I fell for the M05 made in germany Syntec brown crap, called up Castrol had bit of bitch. Told them I won't be purchasing their product anymore till the lable reciprocates what in the bottle consistantly.

In response they said "the performance of this oil isn't compromised, possibly a differnt additive package was used"

me - "really no ****?"

Guess i'm back to M1 0W40, atleast they have some consistancy. Or Royal Purple Racing 41.

absolutely not, don't think cause its a 0W30 oil makes it thin, its actually a very heavy 30 weight oil. Castrol could have passed it off as a 5W30 if they really wanted.

Possibly castrol dropped the more expensive green GC cause of how the dollar is trading. Less profit margin at $5 a quart cause its an imported oil. Why don't they just market the oil for what it really is for more money instead of disquising the oil in a 0W30 container.

Call it Syntec Racing oil or something and sell it for $6.50 a quart, atleast your guarenteed whats in the container instead of resorting to the reading sku number etc. I dislike how castrol plays these "whats behind door #2?" games.

If I have to pay $10 a quart to get Royal Purple or buy M1 0W40 atleast I know whats in the oil container.

OK, here is more info on the new M05 version of Castrol 0w30. I'm pretty confident now that this oil is Castrol's SLX Longtec 0w30. This oil is the same viscosity as the green GC (12.2 cst at 100c) and passes the same specs, plus now it passes MB 229.5 as well. Someone did a virgin oil analysis on the M05 stuff sold here, and we compared it to a VOA done on Longtec 0w30 by someone in Europe, and this pretty much confirms they are the same. That same person posted a used oil report from his 1.8T engine and it looked very good too.

So I was panicking for nothing, it appears Castrol isn't trying to trick us here, but are simply now using the newest version of 0w30 sold by Castrol in Europe. The old green version hasn't been sold over there for a little while now so it was only a matter of time before we ended up getting their newest version over here instead. So once your local store runs out of the green GC, don't be afraid to try the new gold colored stuff.

So we still need to make sure it is made in Germany, right.

THANK GOD...I just put the brownish/gold Castrol 0w30 in my car over the weekend, and thought to myself "Hey, wasn't that supposed to be green?" I thought nothing more of it until now...at least it looks like I'm not hurting anything. I watch the oil pressure guage pretty closely, and it looks like it did with the green stuff. Not that it is a terribly accurate way of telling, but at least nothing looks out of the ordinary, and my car is running like a champ right now.

I still like the greeen stuff better. Even if it is the same, I think green looks better

picked myself up a few quarts today of the MOxxxx GC the greenish tint, says right on the back "As the technology leader, Castrol continually IMPROVES performance through product innovation. This may result in color/odor variations from time to time." also says "NOT FOR SALE OUTSIDE THE AMERICAS". just saw it on the bottle and thought it might pertain to this discussion. also if anyone has trouble finding GC pm me and let me know if i can help! -Jim

Yes, if it says made in Germany, it's good to use, whether it's gold or green. I prefer the green right now since I know for sure it's good, but the gold stuff will be going in my car when the supply of green runs out. I'm confident it's good stuff.
