Reset oil change indicator

I have a 2008 Winnebago 33v and it is telling me to change the oil. It only has @ 1000 miles since last oil change.
1. Does it go by mileage or time between changes?
2. Can I just reset it?
3. If so, how do I reset it.
Thanks for your input!

This is the way Workhorse Chassis is reset:

To reset the Engine Oil change reminder, turn the ignition switch to "ON" position, but do not start. Fully press and release accelerator pedal three times within 5 seconds, and turn ignition "OFF" for at least 10 seconds. The oil life counter on the engine controller will be reset to start a new cycle.

You should perform this operation each time you change the oil.

Are you a Ford or GM chassis?

If this is a Workhorse chassis with a GM engine, it considers several factors in predicting the need for an oil change. Mileage is part of it, but it also factors in operating conditions such as RPMs, engine temperature, etc. to evaluate the probable condition of the oil.

The following quote is from a research paper on oil change prediction methods:

The General Motors (GM) oil-life system, first introduced in 1988, determines when to change the engine oil and filter based on the operating conditions of the engine. The technology does not actually monitor any single quality or physical property of the oil. Instead, the oil-life system records engine revolutions, calculates engine oil temperature and engine oil contamination content. The rate of degradation of the engine oil is calculated by assessing the severity of engine operation as a function of the calculated engine oil temperature and oil.
If yours is calling for a change at 1000 miles, I can only guess that the engine is run only briefly and seldom gets fully warmed up, and maybe often operates at idle as well. Both of those lead to early life contamination of the oil.

I have a GM engine in a big SUV and oil change intervals typically run to 12-15 months and 11,000+ miles, but it runs at highway speeds almost exclusively.
