If you are a Castrol guy, considering going to your local Autozone and trying the Castrol Syntec 0w-30 red label (not yellow) without the API starburst and Made in Germany on the back?
There are some good UOAs from folks that have used it. With the GC, you at least get your $$$ worth.

I'll just chime in here and say that I would never consider Castrol of any flavor, as I hold them primarily responsible for the existance of "fake" synthetic oils... They could make the finest oil in existance and I would not buy it.
Just went to Autozone. No GC here. All the USA stuff.
Castrol is clearly labelled "Not for sale outside the USA." on the container. This obviously means it doesn't fit the rest of the world's definition of syn.
It's good stuff though. I have no illusions.

The one thing which has me curious is why have we seen so many good UOA results on here with Castrol Syntec Blend but their top "full synthetic" hasn't performed as well, despite costing more money.
I would like to see the Syntec 10/40 ran in a good motor . The data sheet looks simalar to the new breed 0/40's like Motul . A very light 40wt with moly I'm guessing .
I wish Castrol provided easy access to their data sheets like Mobil does. Maybe they do and I just haven't found it yet.
I still have a horror of 10-40's from the old days, but I would like to see this info.
I may have to change my opinion of syntec blend after this site. The actual specs. don't really look too good.

I run 5W-30 Syntec, all of my Honda motors have been happy w/ it. I have one UOA on here that was pretty good for how hard I run my cars, the only down side was a slight vis drop.
I would have had a 5000 mile UOA, except before my car reached 5000, it was totaled.
I will have more UOA's in the future.
Also note depending on where you buy Syntec, it's usually at least .50 to $1.00 cheaper than M1.

I am currently running Syntec 10W-40 in the BMW 325i. A UOA is planned for about 8000 miles (one year) and will be posted here. The only thing unique about it so far is the Tide detergent smell.
