What all fluids are there?

windshield wiper fluid. The most vital. Without it, you cannot see out your window clearly and the cannot drive safely.

Engine oil, transmission fluid, power steering fluid, brake fluid, antifreeze, Gasoline or Diesel fuel, airconditioner fluid, Tire air, Differential box oil, Cigarette Lighter Fluid, Windshield washer fuel, convertible top hydraulic fluid, aerodynamic body fluid, Chrome Plated Platinum Louvered Muffler Bearing Grease, Ball Hitch Lube, Horn lube.

Some modern cars don't change fluids, they are sealed. So it depends on the year. But the fluids are engine oil, radiator, transmission, rear end/differential, brakes and power steering. That doesn't include windshield washer fluid....

If it is so simple why are you asking it? O.o
