Anti-lock brakes & Changing Fluid
If you have an anti-lock brake system in your car, you should change your brake fluid every 18 months. If you don't, the parts in the anti-lock mechanism can corrode and the whole part may need to be replaced. The anti-lock brake component for a new F-body car costs about $2,500 to replace. It's cheaper just to have the brake fluid removed and replaced with new fluid than pay to replace a faulty anti-lock brake system.

Take care of your car and it will take care of you. Changing all of the fluids in your car can make it run very reliably for a very long time.

You should change your oil every 3,000 to 4,000 miles with nothing but Synthetic oil. You can get Mobil 1 or Castrol Syntec for about $3.48 a quart. A Buick engine was run with synthetic oil for 200,000 miles and taken completely apart. All of the internal parts were checked with a micrometer and still met factory specifications. The viscosity does not break down in synthetic oil like it does in conventional oil.

You should change your anti-freeze every 20,000 to 30,000 miles. Leaving the old dirty water inside your engine can have it corrode the aluminum parts inside as well as causing the radiator to leak. A bottle of anti-freeze only costs about $5.00 at any Discount Auto stores. Chemicals in the anti-freeze also aid in some of the lubrication of the engine.
