The Difference Between Mineral Oil and Semi-Synthetic Oil

1Answers

07/29/2025, 04:09:15 PM

Mineral oil and semi-synthetic oil differ as follows: 1. Mineral oil is extracted from petroleum. The base oil of mineral oil is the residual bottom oil from the refining process after the distillation of useful light substances (such as aviation fuel, gasoline, etc.), which is then further refined. Mineral oil is currently the most common type of lubricant on the market. Although it is inexpensive, its service life and lubrication performance are significantly inferior to semi-synthetic oil, and it also causes greater environmental pollution. 2. Semi-synthetic oil is a product made from semi-synthetic base oil, specifically international Group III base oil. It is a purified product derived from mineral oil through hydrocracking technology, and its cost is higher than that of mineral oil.

Does the Anti-Slip Light Affect the Car?

The impact of the anti-slip light being on is as follows: 1. Side slipping and rollover: If the anti-slip light remains constantly lit, it indicates a malfunction in the car's anti-slip system. In such cases, it is not advisable to continue driving. If the anti-slip system fails, the car is prone to side slipping and rollover on slippery roads. 2. Safety threat: It severely affects the stability and safety of the car. The anti-slip light may come on under the following circumstances: 1. Slippery road conditions causing the ABS to activate, thus triggering the light; 2. ABS pump failure; 3. Signal transmission error.

What is the purpose of a car's three-way catalytic converter?

The function of a three-way catalytic converter is to transform harmful gases emitted by a car into harmless gases. Below is relevant information about the three-way catalytic converter: 1. Working principle: When high-temperature exhaust gases pass through the purification device, the purifying agent in the three-way catalytic converter enhances the activity of three gases—CO, HC, and NOx—promoting certain oxidation-reduction chemical reactions. Among these, CO oxidizes at high temperatures into colorless, non-toxic carbon dioxide gas; HC compounds oxidize into water (H2O) and carbon dioxide; and NOx is reduced into nitrogen and oxygen. 2. Consequences of damage: If the three-way catalytic converter is damaged, the secondary oxygen sensor on it will fail to provide accurate data to the car's computer, leading to either excessively lean or rich fuel mixture concentration. A lean mixture can cause ignition difficulties, lack of power while driving, engine backfiring, etc., while a rich mixture can increase fuel consumption, result in incomplete combustion, and cause severe carbon buildup in cylinders and spark plugs. When such faults occur, the engine warning light should illuminate.

What is the reason for one side of the rear shock absorber being higher than the other?

One side of the rear shock absorber being higher than the other is due to the forward inertia effect when the car brakes. To prevent the front of the car from rubbing against the ground, the shock absorber is set higher in the front and lower in the rear. Introduction to Car Shock Absorbers: Car shock absorbers, also known as car dampers, typically wear out after driving an average of 20,000 kilometers per year, reaching 80,000 kilometers. At this point, the shock absorber may fail to function effectively and needs replacement. Shock Absorber Maintenance Tips: After driving the car on rough roads for about 10 kilometers, stop and touch the outer shell of the shock absorber. If it is not warm enough, it indicates no internal resistance, meaning the shock absorber is not working. In this case, adding appropriate lubricating oil and retesting may help—if the shell becomes warm, it suggests a lack of oil inside. Press down firmly on the bumper and then release; if the car bounces two or three times, the shock absorber is functioning well. If the car vibrates excessively during slow driving followed by sudden braking, it indicates a problem with the shock absorber.

The following is the relevant introduction of autohold: 1. How to turn on autohold: When the engine is running, the left front door is closed, and the driver's seat belt is fastened, press the "autohold" switch to turn on the automatic parking hold function; the indicator light on the switch button lights up, and the green autohold indicator light on the combination instrument lights up. 2. How to turn off autohold: When the automatic parking hold function is turned on, press the "autohold" switch again to turn off the automatic parking hold function, the indicator light on the switch button goes off, and the green autohold indicator light on the combination instrument goes off.

Can I pick up the car at the 4S store on Saturday?

You can pick up the car at the 4S store on Saturday. When picking up the car, pay attention to checking the production date: Open the engine hood and check the production date to see if there is a significant gap between the production date and the pickup date. A smaller gap means fewer movements, which, although unavoidable in the sales process, reduces the likelihood of the dealer tampering with the mileage. When picking up the car, pay attention to checking the tires: Check if the tires are intact. Tires are a relatively straightforward way to inspect the car. If a new car has been used excessively, the tires will show significant wear. The tire hairs will not be as complete as on a new car, and in severe cases, the tire hairs may be completely worn away, with visible damage marks on the tire surface.
