Back in the '80s, M1 was advertised as "40,000km protection" in Oz, and in the '90s, I had agreement from Mobil with my 4Runner (3VZE) that 40,000km, or 1 year was fine...the "one year" was the clincher, if I did 5,000KM, that represented another type of driving that they suggested should be changed annually also.
