There are a total of 5 letter markings on an automatic transmission, with their specific meanings as follows: 1. P (parking) gear: Represents the parking gear. When parking, shift the gear lever to the P position to lock the output shaft with the transmission's parking brake device, then tighten the hand brake to prevent the car from moving. 2. R (reverse) gear: Represents the reverse gear. Use this gear when reversing the car. 3. D (drive) gear: Represents the drive gear. Used for normal driving, simply place the gear lever in the D position, and the car will automatically adjust the gears while driving. 4. L (low) gear: Represents the low gear. Equivalent to 2nd gear, often used when going up or down hills. 5. N (neutral) gear: Represents the neutral gear. Used when starting the car or towing.

I remember when I first started learning to drive, the letter indicators on automatic transmission cars were really confusing. Later, I understood that P stands for Park, used when turning off the engine or parking for a long time—it locks the wheels. R is Reverse gear; switch to it when backing up, and the car will move backward. N is Neutral, where the car has no power, useful for pushing during car washes or towing. D is Drive, the gear used for normal driving, where the car shifts automatically to move forward. There's also S for Sport mode, which provides faster acceleration, and L for Low gear, great for climbing steep hills. Mastering the meanings of these letters made daily driving much smoother and allowed me to adapt to different road conditions for improved safety.

Can a Car Using 98-Octane Gasoline Switch to 95-Octane?

It is not advisable for a car using 98-octane gasoline to switch to 95-octane, as it may cause the following issues: 1. Affect the normal operation of the engine; 2. Lead to increased car noise, reduced driving power, and potential engine damage. The difference between 98-octane and 95-octane gasoline lies in their octane ratings: 98-octane gasoline is a mixture of 98% isooctane and 2% n-heptane, while 95-octane gasoline consists of 95% isooctane and 3% n-heptane. Different gasoline grades represent varying levels of fuel anti-knock performance, with higher octane numbers indicating better anti-knock properties. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from the distillation, cracking, or pyrolysis of petroleum.

How often should spark plugs be replaced?

The replacement interval for spark plugs varies depending on the material: 1. Nickel alloy spark plugs should be replaced approximately every 20,000 kilometers; 2. Platinum spark plugs should be replaced approximately every 40,000 kilometers; 3. Iridium spark plugs should be replaced approximately every 60,000 to 80,000 kilometers. Commonly known as spark plugs, their working principle is to discharge the pulsed high voltage delivered by the high-voltage wire, breaking down the air between the two electrodes of the spark plug to generate an electric spark that ignites the air-fuel mixture in the cylinder. The steps for replacing spark plugs are: 1. Turn off the engine and remove the spark plug cap; 2. Unscrew the old spark plug counterclockwise; 3. Screw in the new spark plug clockwise; 4. Reattach the spark plug cap; 5. Check for any errors and start the engine for a test run.
