Hello, 'Been maintaining an ever increasing fleet of turboed cars-3 Saab 9-5 2.3l to be specific. The manuals state that ACEA A3,B3 rated oil is preferred in these engines. It's been mentioned on this board before. I just read today on the Amalie oil site that they have an A3,B3 rated mineral oil under their Wolf's Head Super Duty brand. I assumed such an oil had to be a synthetic; GC (German Castrol 0W-30), Mobil 1 0W-40, Amsoil (whatever the "European Formula" oil is) or a Redline product. I've e-mailed the company to ask for particulars. Does anybody know anything about or have any experience with these products from Amalie? At the moment shipping to the US for orders over $19 is free. How can this not be tempting to a turbo owner? Kira
