Mobil 1 10w40 Turbodiesel is available in US & Canada. The supplier I found in Michigan where I am is Vesco Oil (800-527-5358). They sell it by case (6 quarts per case) at @28.08 including free delivery. They also provide some discounts if you buy at list 36 cases. Mobil part number for this oil is 48149.
A couple of dealers I checked with do not have the oil for sale - they have it only in drums.
Hope this helps everyone.
