Why do some car owners try to get the last mile out of a oil change?
Compared to engine damage from dirty oil, they are not that costly.
Even a low price oil and filter changed at 5-8K is better than extending any oil/filter combination. The whole point of a oil change is to get the dirty oil out and clean oil in, right?
I agree with the UOA group, that is the only way to know when oil needs to be replaced.
That mileage is different for every car (even if the same model), because of different driving habits, etc.
Even with a UOA at a high mile interval, it would be better to put the UOA cost into a fresh oil change.
When in doubt, change it out.
Now I wait for the posts to correct my skewed reasoning !
