@tturbotim: You've heard these from your dad, your buddy at the shop and a random guy at the gas station. 😅 Some are outdated advice, and some are legit. Save this post and follow Turbo.Tim for more car facts. 🏁 ⛽ 1. "Premium gas makes any car faster." MYTH ❌ Octane only measures resistance to knock, not energy. If your car runs fine on regular, premium gives you nothing but a lighter wallet. Fun fact: turbocharged and high-compression engines that require premium can pull timing on regular, so the myth flips for them. 🔧 🌡️ 2. "You need to warm up your car for 5 minutes." MYTH ❌ Fuel-injected engines are ready in about 30 seconds. Just drive gently until the temperature gauge moves. Fun fact: this advice comes from the carburetor era, when engines truly needed time to run right. 🕰️ 🛢️ 3. "Change your oil every 3,000 miles." MYTH ❌ Modern synthetic oils and engines often go 5,000 to 10,000 miles. Your owner's manual knows best. Fun fact: towing, short trips and dusty roads count as severe use and shorten the interval. 📖 🛞 4. "Cold weather lowers tire pressure." TRUE ✅ Pressure drops roughly 1 PSI for every 10°F of temperature drop, so check your tires when the first cold snap hits. Fun fact: your TPMS light often pops on the first cold morning of the year for exactly this reason. ❄️ ⏱️ 5. "Idling burns more gas than restarting." TRUE ✅ After about 10 seconds of idling, shutting the engine off uses less fuel. That's why many new cars have auto start-stop. Fun fact: restarting costs far less fuel than most people assume, and modern starters are built for it. 🔑 🚨 6. "Running on empty can hurt your fuel pump." MOSTLY TRUE ✅ The pump sits in the tank and uses fuel to stay cool, so a low tank can run it hotter and wear it faster. Fun fact: it's not a guaranteed failure, but a fuel pump replacement can run hundreds of dollars, so don't push your luck. ⛽ 🏆 Score: 3 myths, 3 true.
