What Are the Consequences of a Car Running Low on Engine Oil?

When a car runs without engine oil, it can lead to engine crankshaft seizure, cylinder scoring, and bearing wear in the engine. Engine oil not only lubricates but also helps in cooling, cleaning, and sealing within the engine. Without oil, engine components operate under dry friction, generating extreme heat instantly, which can cause parts to burn or melt. During operation, engine oil forms a protective film on component surfaces, preventing direct contact and reducing abnormal wear and excessive temperatures between parts. If a car's engine lacks oil, it must not be driven further. In such cases, immediately stop the vehicle in a safe location, turn off the engine, and call for professional assistance. Since the engine relies on oil for lubrication, continued driving with low oil pressure can cause severe internal wear, unusual noises, and part damage. In worse cases, it may lead to bearing seizure, piston burning, and mechanical failure, requiring major repairs or even a complete engine replacement.

What Causes a Car to Lack Power When Starting?

Reasons for a car lacking power when starting: engine carbon buildup, transmission failure, dirty transmission fluid. Engine carbon buildup: Carbon deposits are a major culprit causing insufficient engine power and weak car starts. Carbon buildup on the throttle valve affects air intake; buildup on spark plugs affects ignition; buildup on fuel injectors affects fuel injection, and overheated carbon deposits can cause detonation, leading to weak car starts. Therefore, it's advisable to first clean the engine's carbon deposits before investigating other potential causes of weak starts. Solution: Recommended to seek professional maintenance at a 4S shop. Transmission failure: Clutch failure in the transmission can cause weak car starts. The clutch's function is to transmit and cut off engine power. Manual transmissions, dual-clutch transmissions, etc., use friction plate clutches. Over time, these friction plates wear severely, causing slippage and resulting in weak starts. Solution: Replace the transmission. Dirty transmission fluid: Dirty or insufficient transmission fluid can also cause weak car starts. Besides lubrication, transmission fluid serves as the medium for hydraulic mechanisms inside the transmission. These hydraulic mechanisms control the clutch and gear shifting. If the fluid is too dirty or insufficient, these mechanisms will malfunction. Solution: Recommended to have the transmission cleaned at a 4S shop.

Can 195 and 205 Tires Be Used Interchangeably?

195 and 205 tires can be used interchangeably provided that the wheel rim is marked as 5.5J or 6.0J (rim width). However, if the J-value is larger or smaller, this solution is not feasible because each rim width has a corresponding range of compatible tire widths. Here is additional information: 1. Improved Vehicle Stability: Many car owners who have switched from 195 to 205 tires report feeling that the vehicle is more stable, though the improvement in handling is not significant. Fuel consumption increases, and there is also some loss of power. It is important to note that after widening the tire tread, you should check whether the tire rubs against the fender. If it does, you must revert to the original size, as this poses a safety hazard. 2. Increased Tire Tread Width: Switching from 195 to 205 tires essentially means increasing the tire tread width. Wider tires can indeed provide better grip and lateral force, significantly enhancing vehicle stability. Even during aggressive driving or sharp turns, they can give you sufficient driving confidence.

What Causes Engine Overheating After Driving for a Period of Time?

Reasons for engine overheating after driving for a period of time: severe coolant shortage, water pump failure, cooling fan malfunction. Severe coolant shortage: If the car overheats after driving for a while, it's likely not just a minor coolant deficiency but possibly due to a leak in the radiator pipes. Solution: If you notice insufficient engine coolant, you can refill it yourself, but be sure to purchase the same brand and specifications as the original manufacturer's coolant. Water pump failure: When the water pump fails, the water that cools the engine cannot circulate and renew in time. As a result, after driving for a while, the engine temperature will rise rapidly, and the coolant temperature warning light on the dashboard will illuminate. Solution: Loosen the packing, clear the water diversion channel; disassemble the pump body to remove debris and rust; remove the pump shaft for correction or replacement with a new one. Cooling fan malfunction: This prevents the engine's heat from dissipating, causing the engine temperature to rise. Upon opening the engine compartment, you will naturally feel significant heat. Solution: The car owner needs to promptly visit a professional repair shop for maintenance.

Can You Drive with a Flat Tubeless Tire?

Yes, you can drive. Tubeless tires have an advantage: when punctured by a sharp object, they slowly leak air as long as the object isn't removed, unlike tube tires which quickly lose all air. Here are some additional details: 1. Mounted on the rim: The valve of a tubeless tire is directly installed on the rim, and both the valve and the rim are in a sealed state. If inflating manually, start vigorously to quickly inflate and seal both sides of the tire, then install the valve core and inflate to the specified pressure. Tighten the valve core. If there's no air leakage, it's ready for use. 2. Inflation: When inflating, wrap a piece of cloth or something similar around the area between the tire and the rim before inflating.

How many times should the high and low beams be alternated?

No less than twice. During the lighting test, when you hear voice prompts such as: approaching a sharp curve, approaching a slope, approaching an arch bridge, approaching a crosswalk, or approaching an intersection without traffic signals, you should alternate between high and low beams no less than twice. Here is additional information: 1. The Road Traffic Safety Law stipulates: when driving at night, drivers must alternate between high and low beams in situations such as sharp curves, slopes, overtaking (while also turning on the left turn signal), arch bridges, crosswalks, and intersections without traffic signals; additionally, when overtaking at night, you must not only turn on the turn signal but also use the high and low beam alternation to alert the vehicle ahead; when approaching a crossing, you must use the high and low beam alternation to alert vehicles on both sides of the intersection. 2. Signaling oncoming vehicles to switch to low beams: In fact, when driving on urban roads, the vast majority of high and low beam alternations are used to signal vehicles in the opposite lane to switch to low beams. This is because during nighttime encounters between two vehicles, high beams can cause intense glare, dazzling the other driver and compromising driving safety, and also affect the visibility of pedestrians on both sides of the road.
