Honda's Maintanence Minder is a great system, unlike this Toyota one. MM actually does take other factors into affect. I followed it religiously on my old Accord. The light came on at a different mileage every time, unlike the 4Runner which is always at about 4500 miles. It's stupid with a recommended 10k interval. Granted, it's pretty easy just to reset it and move on with my day.
Why is everyone overlooking the OP's mileages for maintenance minder?
He said it came one at 4400, then 13000, then 18000. This means it does not come on every 4500 or every 5000...
This means it came on after 4400 miles, then again after 8600 miles, then after 5000 miles. Solid data, no conjecture, no assumptions..... it doesn't go off on a purely mileage based equation. If it did, it would come on at 5000, 10000, 15000, etc.
Has anyone else tracked miles traveled between oil change indicator?
