Thanks to you guys, I've been hunting for the green stuff, even though it may not be the best oil for my application. In the search, I came across the belgian made 5w-40. I did a search on this forum and it seems to not get the same kind of love that the german stuff gets. Anyhow after reading some of the posts, it seems that the popular idea is that the BC 5w-40 is the same as the softec TXT 5w-40 that is sold in france, belgium, and south africa. After visiting their site, I found this: http://www.castrol.com/castrol/productdetailmin.do?categoryId=9000612&contentId=7000675 If that link doesn't come up, it states "Castrol TXT Softec provides excellent wear protection under all driving conditions and delivers good cold starting and oil pressure build up. TXT Softec uses fully synthetic base fluids and an advanced formulation to provide the following benefits: Maximum wear protection and deposit control assured Reduced friction allows easier cold starting and faster oil pressure build-up Engine deposits are kept to the minimum possible to preserve engine life reduce ownership costs Maximum possible drain interval intervals for standard applications " Notice it says "fully synthetic base fluids". I'm assuming this means this is a group IV oil then? It IS marketed as a synthetic in these other countries as well. Any thoughts?
