Looks like you accidentally posted in the member's rides section, which is meant for showing off your car. Make sure you post in the appropriate technical section in the future. I went ahead and moved this thread for you.
In regard to your question - This isn't my topic of expertise, but I did a quick search and it seems like 5W-30 and 10W-30 are the most common. Another thing to consider is the mileage of your vehicle. Your car is over 20 years old, so it's likely you have high mileage. If so, you might want to consider using a high mileage oil.
I cleaned this thread. To those who posted previously, it is not acceptable to reply with "search", and it is DEFINITELY not acceptable to reply with false information.
