If you (change the oil and) reset the maintenance minder/oil life display at 20%, then you'll miss seeing the codes for all of the other required maintenance items that don't appear until the oil life gets down to 15% or less.Thank you for your input, thats gives me an idea on how often should be change.
with 150,000 on the clock my plan is to change it every 5,000 miles so I guess at about 20 percent of life.
Good point xGS,If you (change the oil and) reset the maintenance minder/oil life display at 20%, then you'll miss seeing the codes for all of the other required maintenance items that don't appear until the oil life gets down to 15% or less.
The "maintenance due soon" message is not the same as the "maintenance due now" message.I change my oil every 6,000 miles regardless of what the MM reads. However I do not reset the MM until it hits 15% so I can see the suggested maintenance codes when they come up. Then I reset it to 100%. Before I began this routine, the MM hit 15% around 9,000 miles after the previous oil change, give or take. I do a lot of highway driving, not sure if my MM results/mileage would be the same if it were more city driving. So now I end up with 3 oil changes in the same mileage (i.e.: 18,000 miles) that used to take 2 oil changes when I strictly followed the MM. I am doing it this way because I had to make some long trips (i.e.: 1,500 to 2,000 miles) when the MM was sitting at 30%. On one occasion I had to interrupt a trip for an oil change 600 miles from home when the "maintenance due soon" notation came up along with the infamous 15% number on the dash. I hated that experience, so I decided to take control of scheduled maintenance by doing more than the MM code required.
