Shell use group 1 in there red and yellow bottle, Helix pLus is group 3 blended with group 1. Valvoline Durablend is also GP3 with group 1. Rest of range is the same except for Synpower which is group 3. Castrol is also group 1 in the GTX range, including the Magnatec. They may possibley be reaching SM with Group 2, but i am sure its Group 1 with group 3 blends or ester. Edge range is Synthetic Penrite use majority Group 1, the semi synths again all blended with group 3. Everyday Synth is group 3, Sin range is PAO and Ester. Mobil use Group 1 in their Super 2000 range and 1000 range. Super 3000 range is Group 3 and MObil 1 is PAO and whatever is discussed on here on numerous occasions. Even Pennzoil who are not that big here are GRoup 1, even when they dont use it in the U.S anymore. Because most of them are blended in Singapore by Shell, using GRoup 1, most of Shell oils are only SL still. Platinum and some of the diesels are group 3 and group 2 due to fantastic specs, and High mileage is now exactly the same as U.S specs, same tech sheet. The Synthetic blend they have told be is group 1 and 3 blended in Singapore. All their others are group 1. Even though Johnny told me U.S Pennzoil dont use Group 1, we still imprt Group 1 Pennsoil the GT Streetmachine was GRoup 1 they told be. I still have all the emails somewhere. Caltex i am sure still blend with GRoup 1. THey all use GRoup 1 in all exept the Synthetics and some of the Diesel oils.
Who else is left ??? These are the main oils on the Shelves as K-Mart, Supercheap, Repco and Autobarn..... If any of these oils can be confirmed to me to be at least Group 2 and above or proven otherwise i will use them.
I have asked this question here before about our base oils, MObil, Shell etc are only refining GRoup 1 here, due to its quality i am told. Group 3 from Korea and Singapore. I am not sure where the PAO and Ester is from for Aussie blended oils (Mobil 1 etc).
