How to Change Oil
- Run the engine long enough to get it thoroughly warm, park it on level ground, and turn it off. On a small engine, disconnect the spark plug wire for safety.
- Put a bucket or basin under the oil drain plug (some engines may have a tube).
- Unscrew the plug, and drain the oil into the bucket.
- If there is a filter, remove it with an oil filter wrench, and replace it with a new one, first wiping the bottom of the new filter or its gasket (if it has one) lightly with oil to ensure a good seal. Snug the new filter down by hand, and give it an extra quarter turn with the wrench.
- Replace the drain plug; snug it down firmly, but don’t overtighten.
- Add the specified amount and type of new oil at the oil cap or the dipstick tube.
