honda using excessive amount of power steering fluid
What year and engine?
No sign of external leaks (spots on the driveway - wet pump, hoses, gear)?
Approximately how much fluid are you losing?
Some vehicles use a vacuum regulated switch tied into the power steering system. These switches can leak internally, allowing the engine to actually burns up the PS fluid in the combustion chamber.
Give me more information so I can see if it applies to your Civic.
