Preventative Maintenance & Cost Saving Tips

Almost every expensive repair we see started as a cheap one somebody put off. That's not a lecture - it's just the pattern. Below is what actually saves money, in the order it saves the most.

The 10-minute check before a long trip

Ten minutes in the driveway prevents most roadside breakdowns.

Fluids. Engine oil, coolant, brake fluid, power steering, transmission, washer fluid. You're looking at level and color - dark, gritty, or milky fluid tells you more than a low level does.

Belts and hoses. Squeeze the radiator hoses when the engine is cold. They should feel firm, not spongy or crunchy. Look at the serpentine belt for cracks across the ribs. A belt failure takes out the alternator, water pump, power steering, and A/C all at once.

Tires. Check pressure cold, including the spare. Look for uneven wear - wear on one edge means alignment, wear in the center or both edges means pressure. Check for bulges in the sidewall; a bulge is a tire about to fail.

Lights and wipers. Walk around with the car running and have someone tap the brakes. Replace wiper blades that chatter or streak.

Battery. Corrosion on the terminals, or a battery over four years old going into winter, is worth testing before it leaves you somewhere.

Fuel economy: what actually works

Most fuel-saving advice is noise. These four are measurable:

1. Correct tire pressure. Underinflated tires cost you 3% or more, and they wear out faster on top of it. Check monthly. 2. Ease off the pedal. Hard acceleration and hard braking cost 15-30% on the highway. Smooth driving is the single biggest lever you control. 3. Slow down. Fuel use climbs sharply above about 55 mph. Running 65 instead of 55 costs roughly 15-20%. 4. Fix the check engine light. A dead oxygen sensor or a fouled plug can cost up to 30% in fuel economy while feeling completely normal to drive.

Also worth doing: drop the extra weight out of the trunk, take the roof rack off when you're not using it, and don't idle for more than a minute - restarting uses less fuel than idling.

Not worth doing: premium fuel in an engine that doesn't require it. If your manual says 87, buying 93 buys you nothing.

The repairs worth doing early

Some jobs get dramatically more expensive if you wait. These are the ones:

| Do it now | Or pay for this later | |---|---| | Brake pads | Pads and rotors, sometimes a caliper | | Alignment | A full set of tires, gone in a few thousand miles | | Coolant leak | Overheating, warped head, head gasket | | Timing belt at interval | On an interference engine, a destroyed engine | | Small oil leak | Low oil, bearing damage, engine failure | | Transmission fluid service | Transmission rebuild or replacement |

Where people waste money

• Replacing parts to chase a symptom. Get it diagnosed first. Guessing costs more than testing.
• Skipping the free rotation. If tires were bought with rotations included, use them. It's the difference between 40,000 miles and 60,000.
• Waiting for a "convenient time." Repairs don't hold still. They get worse on their own schedule, usually on a weekend.
• Only fixing what's broken. A car inspected twice a year rarely surprises you. That predictability is worth more than the inspection costs.
