I've been keeping an eye on automotive technology, and the BMW 730 now mostly features four-cylinder engines. For example, the latest G70 series uses a 2.0-liter turbocharged inline-four engine, delivering approximately 258 horsepower. While some might think a four-cylinder isn't powerful enough for such a large luxury car, it actually responds quite quickly when driven, accelerating from 0-100km/h in just about 6 seconds, making overtaking in the city no problem at all. It's also fuel-efficient, with an average consumption of around 8L/100km, making it both eco-friendly and economical to maintain. In comparison, older 730 models might have had six-cylinder engines, but the trend now is toward smaller displacements without sacrificing power. When choosing a car, I recommend test-driving it to feel the power delivery—don't let the number of cylinders scare you.

I've driven the BMW 730 many times, and its four-cylinder engine doesn't feel underpowered at all. Starting at traffic lights in the city is smooth, and it's stable on the highway. BMW designed it this way to save fuel and reduce taxes. Although the engine sound isn't as nice as a six-cylinder, it's more than sufficient for daily use. Maintenance costs are also lower than those of larger engines, saving a significant amount on fuel each year. However, the noise is slightly louder during highway cruising, which is a minor drawback. Nowadays, cars are trending toward energy efficiency, making four-cylinder engines more suitable for the average driver.

According to the data I've checked, the BMW 730 engine is generally a four-cylinder. Modern versions like the 730i use a 2.0T turbo with a sufficient horsepower of 258. This design prioritizes environmental protection, offering small displacement but strong performance, delivering quick acceleration when driving. There might be occasional noise issues, but you get used to it. Choosing this type of car mainly depends on practicality and economy.

do baby car seats expire

Yes, baby car seats have expiration dates, typically between 6 to 10 years from the date of manufacture. Using an expired car seat is a significant safety risk. The primary reasons for expiration are the degradation of plastic and other materials over time due to temperature fluctuations and exposure to sunlight, which can cause the seat to crack or fail in a crash. Additionally, safety standards and technology evolve, meaning an older seat may lack critical safety improvements. You can find the expiration date stamped on the plastic shell of the seat, often on the back or bottom. It might also be printed on a sticker with the model number and manufacturing date. Most manufacturers also include it in the owner's manual. If you cannot locate it, contact the manufacturer directly with the model number. Reason for Expiration Key Considerations Typical Industry Guideline Material Degradation Plastics become brittle and may not withstand crash forces. 6-10 years Outdated Safety Standards Lacks newer features like side-impact protection. Varies by model year Missing Parts/Instructions Increases risk of improper installation. Check immediately Recall History Older models may have unresolved safety recalls. Check NHTSA website Never buy a used car seat unless you know its full history and can confirm it has never been in an accident. If a seat has been in a crash, even a minor one, it should be retired immediately, as its structural integrity is compromised. When a seat expires, the best practice is to dismantle it (following the manufacturer's instructions to prevent reuse) and dispose of it, often through a recycling program if available. Your child's safety is paramount, and an up-to-date, properly installed car seat is your first line of defense.

does costco sell car oil

Yes, Costco does sell car oil, primarily under its highly regarded Kirkland Signature brand. They offer full synthetic and synthetic blend motor oils that meet or exceed industry standards (like API SP) at a significantly lower price than many auto parts stores. You can typically find popular viscosities such as 5W-30 and 5W-20. However, Costco's selection is limited compared to specialized retailers, often stocking only a few high-demand types. It's exclusively an in-warehouse item, not available for online purchase, and availability can vary by location. The primary draw is the value. Costco sells motor oil in bulk packs, usually two 5-quart jugs, which is enough for most oil changes with some left over. This bulk pricing model makes it an excellent choice for households with multiple vehicles or for those who perform their own oil changes regularly. Feature Kirkland Signature Full Synthetic 5W-30 Mobil 1 Full Synthetic 5W-30 (for comparison) Viscosity Grades 5W-30, 5W-20 0W-20, 5W-30, 10W-30, etc. API Certification API SP API SP Quantity per Pack 2 x 5-Quart Jugs Typically 1 x 5-Quart Jug Approx. Price per Quart ~$3.50 - $4.00 ~$7.00 - $9.00 Deal Frequency Regularly stocked, occasional instant savings Frequent sales & rebates at auto parts stores Before making a trip, it's wise to call your local warehouse to confirm they have the weight your vehicle's manufacturer recommends. Your owner's manual will specify the correct viscosity and the required performance standard. If you need a specific niche product, a high-mileage formula, or just a single bottle, a traditional auto parts store will offer more flexibility, though at a higher per-quart cost.

do cars use gas for heat

Yes, most traditional gasoline and diesel-powered cars do use gas (fuel) to generate heat for the cabin. This is done through a clever system that repurposes waste heat from the engine. However, electric vehicles (EVs) operate differently and use battery power for heating, which can impact their driving range. The system in a conventional car is called a heater core . It works like a small radiator. Hot engine coolant, which absorbs excess heat from the engine block, is circulated through a small radiator-like unit located behind the dashboard. When you turn on the heat and adjust the temperature dial, a blend door opens, and the car's fan blows air across the heated fins of the heater core. This warm air is then directed through the vents and into the cabin. Because this heat is a byproduct of the engine's normal operation, using the heater in a gas car has a minimal direct impact on fuel economy—the engine is producing the heat regardless. Electric vehicles don't have a large, hot engine, so they must create heat electronically. Most use an electric resistance heater , which functions like a large space heater, drawing significant power from the high-voltage battery. Some newer, more efficient EVs use a heat pump system, which works like an air conditioner in reverse to transfer ambient heat from the outside air into the cabin. Using the heater in an EV actively consumes battery energy, which is why driving range can decrease noticeably in cold weather. Vehicle Type Primary Heating Method Energy Source Impact on Efficiency/Range Gasoline/Diesel Car Heater Core (engine coolant) Waste heat from engine Minimal direct impact on fuel economy EV (Resistance Heater) Electric Resistance Heater High-voltage battery Significant reduction in driving range EV (Heat Pump) Heat Pump System High-voltage battery More efficient, lesser impact on range than resistance heater Hybrid Vehicle Combination of heater core and electric heater Engine waste heat & battery Varies based on driving mode; electric heating can use fuel

do cars have spark plugs

Yes, most cars on the road today have spark plugs , but it's not a universal rule. The answer depends entirely on the type of engine. Vehicles with traditional gasoline engines require spark plugs to ignite the air-fuel mixture. However, diesel engines operate on a principle called compression ignition and use glow plugs instead for cold starts. Furthermore, fully electric vehicles (EVs) like Teslas have no spark plugs whatsoever, as they are powered by electric motors and batteries. A spark plug is a critical component responsible for creating the electrical spark that ignites the compressed air-fuel mixture in an engine's cylinder. This small but powerful explosion is what drives the piston down, creating the power that turns your car's wheels. The condition of your spark plugs directly impacts engine performance, fuel efficiency, and emissions. Here’s a quick breakdown of which vehicles have them: Vehicle Engine Type Requires Spark Plugs? Ignition Component Key Function Gasoline/Petrol Engine Yes Spark Plug Creates an electrical spark for ignition. Diesel Engine No Glow Plug Heats the combustion chamber for compression ignition. Hybrid Vehicle (Gasoline) Yes Spark Plug Ignites fuel during gasoline engine operation. Fully Electric Vehicle (EV) No N/A Uses electric motors powered by a battery pack. Natural Gas Vehicle Yes Spark Plug Functions similarly to a gasoline engine. For gasoline car owners, worn-out spark plugs can cause noticeable issues like rough idling, difficulty starting, reduced acceleration, and higher fuel consumption. Most manufacturers recommend replacing them anywhere between 30,000 and 100,000 miles, depending on the plug material (e.g., copper, platinum, iridium). Checking your owner's manual is the best way to know your specific car's maintenance schedule.

does lowes make car keys

Yes, many Lowe's stores offer car key copying and programming services for a wide variety of modern vehicle keys, including basic transponder keys and more advanced key fobs. This service is available at their Key & Code Kiosks , which are typically found in the hardware section. However, availability depends on your specific key type and whether the in-store machine has the required blank key and programming capabilities. The process is generally straightforward. You bring your existing key to the kiosk, and an on-screen guide walks you through selecting your vehicle's make, model, and year. The machine will then cut a new key and, if necessary, program it to match your car's immobilizer system. This is a significant advantage over hardware stores that only cut basic metal keys. Service Aspect Details at Lowe's Important Considerations Key Types Handled Transponder keys, key fobs, basic laser-cut keys. Does not handle proprietary smart keys (e.g., Tesla, some BMW). Cost Range Typically $30 - $150, depending on key complexity. Often cheaper than a dealership but more than a basic copy. Vehicle Compatibility Covers most major brands like Ford, Chevrolet, Toyota, Honda. Always call your local store to confirm they can service your specific vehicle. Service Time Usually completed in under 15 minutes. Complex programming or lack of blank keys may cause delays. Alternative Providers Home Depot, Ace Hardware, locksmiths, car dealerships. Dealerships are the most expensive but guarantee compatibility. Before heading to Lowe's, it's crucial to call your nearest store to verify they can handle your specific key. For older cars with simple metal keys without chips, a basic key-cutting service at any hardware store will suffice. For modern vehicles, Lowe's provides a convenient middle-ground solution between a high-cost dealership and a mobile locksmith.

do electric cars use gas

No, a fully electric car does not use gasoline. It operates exclusively on electricity stored in a large battery pack, which powers an electric motor to drive the wheels. Vehicles that do use gas, like hybrids, are not considered fully electric. An electric vehicle's "fueling" process involves plugging into a charging station, from a standard household outlet to a high-powered public DC fast charger. The core of a Battery Electric Vehicle (BEV) is its high-voltage battery. This battery needs to be recharged by connecting to an external power source. There are three main levels of charging: Level 1 Charging: Uses a standard 120-volt outlet. This is very slow, typically adding only 3-5 miles of range per hour, and is best for overnight topping off. Level 2 Charging: Requires a 240-volt outlet, similar to a clothes dryer. This is the most common type for home installation and public stations, adding about 20-30 miles of range per hour. DC Fast Charging: The quickest option, found at dedicated public stations. It can charge a battery from 10% to 80% in as little as 20-40 minutes, depending on the car and charger capability. For comparison, here are some key differences between a BEV and a standard gasoline car: Feature Battery Electric Vehicle (BEV) Gasoline Vehicle Power Source Electricity from a battery pack Gasoline from a fuel tank "Refueling" Method Plug-in charging Pumping liquid fuel Tailpipe Emissions Zero direct emissions Produces CO2 and other pollutants Key Components Battery, electric motor, inverter Internal combustion engine, fuel system, exhaust Maintenance No oil changes, fewer moving parts Regular oil changes, spark plug replacements Typical Range 250-400+ miles on a full charge 300-450+ miles on a full tank Acceleration Instant torque for quick off-the-line speed Power builds with engine RPM The driving experience is also different. BEVs are known for their quiet operation and immediate acceleration because the electric motor delivers maximum torque instantly. While the upfront cost can be higher, owners often save significantly on fuel and maintenance over the vehicle's lifetime.
