I just changed the oil in my 2001 Hyundai Tiburon today. I know it's not the same year as yours, but I put 4 quarts in mine. I checked the stick under the hood and it showed that it was about full.
A 2001 HYUNDAI TIBURON WILL TAKE APPROX. 3.7L
It should say in your owners manual.
About 2.75q with a new filter, and about 2.5q if you are just changing the oil
6 qts.
690ml oil and filter, 660ml for just replacing the oil
The 4.7 V-8 hold 6 quarts
A 4 cylinder takes 4 and 1/2 quarts
Find the dipstick and pour oil in carefully, half quart at a time, till it comes to just below 'Max'.
5w30
5w30
Depends on what motor V8 or V6 both have different capacities v6 is 5.2L and v8 is 6.2L
Probably any car oil.
