my canadian spec. 2004 echo. h/b calls for OCI of 5000miles/6months. I just found this in Toyota GB website which states OCI of 10000miles.
"Running Costs
Service intervals are set to 20,000 miles with only a half-hour check-up required every 10,000 miles in which the oil and filter are changed and other consumables are checked. "
What is going on here?
