How should I maintain my Audi 80's engine?

I recently purchased an Audi 80 and I want to make sure I am properly maintaining the engine. Can you provide any tips or advice?

Regular oil changes are essential for the health of your Audi 80's engine. This should be done every 5,000 miles or as recommended in your owner's manual.

Make sure to check your oil levels regularly and top off if necessary. Low oil levels can cause major damage to your engine.

Consider using high-quality synthetic oil instead of conventional oil. It provides better protection and performance for your engine.
