What is the shelf life of engine oil?

How much oil do I put in my car?
To get an idea of how much oil you need; the gap between the marks on the dipstick usually represents around 1 litre of oil, so you know that if your oil mark was at the minimum, you need around a litre to top it up. If it’s only halfway down, you probably need around half a litre.
What happens if oil level is above Max?
Overfilling with oil can cause foaming, which turns a slippery lubricant into a sudsy fluid with air bubbles that diminish the lubricating and cooling properties.
