The owner's manual will recommend what grade of fuel (ie. 85, 86, 87, 92 octane) the vehicle is designed for.  Using higher grades than what is recommended may not have any noticeable performance improvements.  It may also rob performance and fuel economy.

Proper tire inflation.  Follow the label on the inside of the driver's front door.

Clean and unrestricted air filters.

Regular oil changes. Non-aggressive driving habits.

Using cruise control on the highway.

Maintaining safe driving and stopping distances.

Using Auto 4X4 and 4X4 only when road conditions are slippery.

Limit use of defroster.  Air conditioning compressor runs, robbing horsepower and fuel economy.

Proper wheel alignment.

Will provide the most life out of your tires.

Prevents radial pulls, chopping and uneven tire wear.

Better fuel economy.

Cleaner and well lubricated moving engine parts will increase engine life.

Better fuel economy.

Prevents uneven tire wear.

Prolongs tire life.

Provides better handling.

Better fuel economy.

Note:  GM has designed your vehicle with specific tire pressure recommendations on the driver's inside front door label.  Provides for the best performance and fuel economy.

Brake pulsations are caused by the following:

Aggressive braking. Worn or damaged wheel bearings and hubs.

Stuck or frozen calipers, pins and slides.

Rust and pad material accumulation on rotor surface.

Out of round brake drum or failed drum brake hardware.

Frozen parking brake cable

Worn out brake linings, pads or shoes.

All of these things can cause excessive heat build-up on the rotors or drums resulting in brake pulsations.

On a normal operating vehicle, this is caused by various accessories on at once.  The alternator is turned "on" in stages (pulse with modulation) by the engine control module (ECM) based on the demand of the electrical system.  When demands are less, the alternator output is reduced putting less resistance on the engine increasing performance and fuel economy. 

Removes deposits and gum from the nozzles, seats, springs and needles or balls.  

Improves fuel spray patterns.

Longer injector life.

Better fuel economy.

Removes carbon and coke build-up(a by-product of combustion) from throttle plates, intake manifold and valves.

Allows the engine to mix air with the fuel creating better atomization.

Better performance, idle quality and fuel economy.
