When checking the oil level on a Briggs and Stratton engine should the dipstick be screwed down or just pushed in?

When checking the oil level on a Briggs and Stratton engine, the dipstick should be just pushed in without screwing it down. This allows you to get an accurate reading of the oil level. After removing the dipstick, wipe it clean before reinserting it to check the level again. Always ensure the engine is on a level surface for the most accurate measurement.
