What is the correct procedure for checking the engine oil level with the dipstick (varilla medidora)?

1. Check with the engine running at maximum RPM on a steep incline
2. Park on a flat, level surface, turn off the engine, wait a few minutes for oil to settle into the oil pan, pull and wipe the dipstick clean, reinsert it fully, and verify the oil level is between MIN and MAX marks
3. Check only once every 5 years during major engine overhaul
4. Pour 5 liters of oil without checking the dipstick level
