quote:Yes. At least two VOAs have been posted, and several UOAs. My theory is that this oil is about 80% Group V (esters) and 20% Group III. The primary component of the base oil blend has to be esters because of the extremely low pour point this oil has (-81°F). A predominantly PAO or Group III oil simply could not have a pour point that low.
Originally posted by ruking77: Perhaps this has been discussed before, but is the Euro Castrol a group 111 synthetic oil? Has any virgin and used oil analysis test been run on this product?

Originally posted by Cutehumor: I have looked for the german castrol as well. but here in Memphis. the temps are in the high 90's in the summer and in the winter high 20's in january. might not see it until the winter if at all. I think alot of people are still scared of the 0w-30 weight even if it is a synthetic for some reason. some stores might think it might collect dust on their shelves.
quote:Another German Castrol post, oh boy. Well, it seems the US one is the same so don't worry about trying to find the A3 one. Do we have a VOA of the US syntec to end this debate? Lately, I'm perfectly fine with a lower viscosity oil. 12.1cst is almost a 40wt so you probably will loose a few HP and MPG in your Civic. For a LS1 this would be idea, but a Civic would probably do better with M1 0w-20 IMO.
You can't beat a 12.1 vis at 100 C!!! $4.99 a quart for an oil composed mainly of esters
quote:It could very well be 20% Group IV. As for the European "laws" and what can and can't be called "full synthetic," no one on here has uncovered the magic formula yet. But by digging arround on some European web sites and looking at various MSDS sheets, it seems that if the PRIMARY component in the base oil blend is Group IV or Group V, an oil can be labeled "full synthetic." It can still have some Group III (or Group II or I) in it, but the primary component has to be Group IV or V. If the primary component of the base oil blend is Group III (even if it has some Group V in it), it can't be labeled "full synthetic." As an example, the MSDS for Shell Helix Ultra 0w40 lists PAO at about 60%, XHVI (a Group III) at about 20%, and esters at about 10%. This oil is labeled "full synthetic."

quote:guitargeek, First find a 0W30 bottle with the weight in a RED not YELLOW block and then look on the back for this (courtesy of G-Man II) The back is the important thing because there are a few red label bottles that are not from Germany.
