Temecula’s Top 10 Car Care Myths (Busted!) — And the Real Maintenance Tips Every Driver Needs

Temecula drivers are no strangers to sizzling summers, stop-and-go I-15 traffic, dusty vineyards, and the occasional “surprise storm” that makes everyone forget how wipers work. And with all that, the myths about car maintenance spread faster than a Saturday line at the Temecula wineries.

So today, we’re breaking down the Top 10 Auto Care Myths Temecula drivers still believe — and the real maintenance facts that keep your car running right. And because trust matters: Excellent Auto Care & Tire has been in the same location, same owners, same honest approach for 30+ years. No upsells. No games. No shady “your blinker fluid is low” nonsense.

Let’s get into it.

Checking engine oil level in a car engine bay

MYTH 1: “If my oil light isn’t on, I don’t need to check my oil.”

TRUTH: By the time the light comes on, your engine is already begging for mercy.

In Temecula’s heat, engine oil breaks down faster. Check your oil monthly, especially before road trips or wine-country weekends.

EAC Pro Tip: Use the manufacturer-recommended oil grade — not the “cheapest jug from the gas station.”

---

MYTH 2: “All tires wear out the same, so I don’t need to rotate them.”

TRUTH: Front tires take a beating — especially on I-15 merges.

Rotating every 5,000–7,000 miles extends tire life and improves handling.

EAC Pro Tip: Temecula temperature swings affect pressure, so check PSI monthly.

---

MYTH 3: “My car doesn’t overheat, so my cooling system is fine.”

TRUTH: Heat damage happens long before the needle moves.

With summer temps pushing triple digits, your coolant and hoses work overtime.Check coolant levels regularly and flush every 2–3 years.

EAC Pro Tip: If you see dried coolant residue (white or green crust) — that’s a leak.

---

MYTH 4: “Air filters only need replacing when they look dirty.”

TRUTH: In Temecula, dust and pollen clog filters way faster

than you think.

Check every 12,000–15,000 miles, or sooner if you live near dirt roads or drive through wine-country dust clouds.

EAC Pro Tip: A clogged filter can tank your MPG — no one wants that.

---

MYTH 5: “Brake squeaks are normal… right?”

TRUTH: They’re a warning sign — and ignoring them

gets expensive.

Brake pads save your rotors. Rotors save your wallet. Inspect every 10,000 miles and replace pads promptly.

EAC Pro Tip: Grinding = metal on metal = emergency.

---

MYTH 6: “Batteries only fail in winter.”

TRUTH: Temecula’s heat can zap a battery faster than cold

ever will.

Heat evaporates battery fluid and weakens internal components. Test annually and replace every 3–5 years.

EAC Pro Tip: Corroded terminals? That’s a starting problem waiting to happen.

---

MYTH 7: “If my lights look fine, they’re fine.”

TRUTH: Sun, dust, and age can dim headlights by 50% —

without burning out.

Check headlights, brake lights, and turn signals monthly.

EAC Pro Tip: Foggy lenses? EAC can restore clarity and improve night visibility.

---

MYTH 8: “Wiper blades last a year, easy.”

TRUTH: Temecula sun cooks wiper rubber like a pancake on asphalt.

Replace wipers every 6–12 months or if they leave streaks.

EAC Pro Tip: Keep washer fluid topped — it’s your best friend during surprise downpours.

---

MYTH 9: “Maintenance schedules are just suggestions.”

TRUTH: They’re the single best tool to avoid expensive repairs.

Your manufacturer’s schedule exists for a reason — it protects your engine, transmission, and warranty.

EAC Pro Tip: Keep a simple log. Your future self (and resale value) will thank you.

---

MYTH 10: “Shops always upsell unnecessary repairs.”

TRUTH: Some do. EAC doesn’t — and our history proves it.
