How do I read the markings on my engine oil dipstick?

No, by adding that much oil, you’ll almost certainly be overfilling the engine which is no good for it at all. It’s a fair bet that an engine that needed an extra seven litres of oil added has already blown up. Which means you can ignore the numbers; they’re probably a part number or batch number.

What you’re looking for are two holes at the very end of the dipstick. The oil level should be between those holes. For whatever reason, Mitsubishi used holes in the dipstick rather than a high and low mark stamped into it. But it works just the same. Keep the oil level between those holes and you’ll be fine.
