Typically most forign cars hold around 5 quarts. I would recomend you buy a 5quart container and a 1 quart container of oil and pour in 4 quarts, start your car for 10 seconds and turn it off, check your oil lvl if you need to add more add 1 more quart and so on.
For a 1999 Solara v6, the oil capacity is 5 qts. of 5W30.
The oil pump is in the oil pan (aka the "sump").
3.6 liters
4 quarts for 2.4 4 cyl and 5 qts for v6

STP's part number is S3614. This oil filter fits a 2006 Toyota Solara (6 cyl) and other similar years of Toyota.
if it is a four cylinder it is most likely 4.2 to 4.6 capacity.
For my 2002 Echo it is 3.7 Liters with a filter change.
6.5 qts
Check your owners manual. I think you'll discover you need 5 quarts with filter change. Cheers
