How to prolong the life of your Audi 80's engine?

I recently purchased an old Audi 80 and I want to take good care of its engine. What measures can I take to ensure its longevity?

First and foremost, make sure to perform regular oil changes and use high-quality oil. This will keep the engine well-lubricated and prevent premature wear and tear.

Keep an eye on the engine temperature and make sure it doesn't overheat. Use a good quality coolant and have the cooling system checked regularly.

Avoid harsh driving and sudden accelerations. This puts unnecessary strain on the engine and can cause damage over time.
