BC that is HIGHLY illegal. If it says made in Germany its the real stuff. Plus you can use the bottom stamp on the bottle to tell also.

http://www.bobistheoilguy.com/forums...&Number=718643Thats the FAQ on bobistheoilguy. It explains the bottom stamp and how to decode it.

Its totally different. My last 6 quarts had 4 that were goldish in color and 2 that were the old greenish tint. Talk about funky looking oil.

I just called castrol and there tech told me it did not matter if it said european formula or not 0-30 all has the same formula he said it did not matter were it was "formulated" , I said so why the different bottles,he said "that the GC that is still out on the will eventually go away and all you will se is 0-30 but it will be the same stuff" he said "the oil was formulated to cater to BMW and Mercedes and that type of consumer is not going to change there own oil so they had to change there marketing stagies".

The GC has to meet MUCH higher specs in Europe. The oil guidelines in the US are very very very vague. Hell a Group II base oil can be called a fully synthetic now.

Did a VOA (no TBN measured) with Blackstone on 5-08 with oil from a bottle with production code beginning with M07... which I believe means produced in 2007.

The following elements/properties were identified;

iron 1 ppm
silicon 6
sodium 6
calcium 1957
magnesium 618
phosphorus 933
zinc 1160

SUS at 210 F 66.3
cSts at 100 C 11.97
flashpoint 455 F

All other elements/properties were listed as nil or 0.

Blackstone comments: Nothing wrong with this oil and it has a strong viscosity for a 0w-30...in the range we often find for 10w-40s.
That is a used oil analysis for the GC when it was brand new.

Went on a scavenging hunt to find this. This is from the ACTUAL US site.

SAE 0W-30: Castrol SYNTEC 0W-30 European Formula is engineered to meet the Mercedes Benz 229.5
specification*. The 0W-30 viscosity grade is ideal for winter conditions where low temperature pumpability is
required. A unique, low-temperature formulation provides exceptional pumpability in cold weather and allows for
unaided engine starts down to -40ºF. Exceeds all car and light truck manufacturer’s warranty requirements for the
protection of gasoline, diesel and turbocharged engines where API SL, SJ, SH, CF or CD is recommended.
Exceeds European ACEA: A3, B3, B4; VW 502 00, 505 00, 503 01; MB 229.1, 229.3, 229.5; BMW LL-01; GMLLA-
025, GM-LL-B-025 and the engine protection requirements of ILSAC GF-3 for API Certified Gasoline
Engine Oils.
Now this is from the GERMAN site.

MB 229.3 und 229.5
GM-LL-A-025, GM-LL-B-025
VW 502 00/503 01/505 00
BMW Longlife 01
ACEA A3/B3/B4
API SL/CF
The only thing I find different is the US brand meets the MB 229.1 requirement which IIRC is a less stringent requirement therefor requiring "worse" oil.


I posted on BITOG so we shall see.

Only problem with that is you end up paying $9.50 a quart for it.

Also it was posted by a pepboys employee that they now carry it as of Aug 1st. Suppose to have 12 quarts on the shelf.

Look at post #49. If the bottle looks like that and has made in germany on the back its the "good" stuff.

Thanks I looked at the pics on post #49; mine doesn't look like that and doesn't say made in Germany on the back. Bummer!

Also, I posted on BITOG and the thinking over there is its just a cookie cutter responce when asked about the European Formula 0W30. It IS a different formula but Castrol seems intent on hiding it.

Virgin UOAs have proved this.

The only difference is the size of the filter. The pf46 is the stock size and the pf57 (not sure of the numbers) is like 1.5" longer.
