How many quarts of oil are needed after new filter for a 1995 Pontiac Firebird 3.4L?
Listed in your Owner's manual, but you probably don't have one or you would have looked. It will be at least 4.5 qts. Put that amount in, start the engine, run for 1 minute, shut it off and wait for 15 minutes, check the level. Add until it is full. You will then know how much it holds.
