Can You Still Drive with 5% Oil Life Remaining?

[IsabelleLee]

You can still drive with only 5% oil remaining, but the distance you can travel depends on the type of oil used (mineral oil, semi-synthetic oil, or full synthetic oil). For example, when using mineral oil with 5% oil life remaining, you can typically drive up to 250 kilometers. Functions of Engine Oil: Friction Reduction: A sufficiently thick oil film separates the surfaces of sliding parts, thereby reducing wear. Sealing: Engine oil forms a seal between the piston rings and pistons, reducing gas leakage and preventing contaminants from entering. Rust Prevention: Lubricating oil adheres to part surfaces, protecting them from contact with water, air, acidic substances, and harmful gases. Cushioning: When cylinder pressure rises sharply, the load on pistons, piston rings, connecting rods, and crankshaft bearings increases suddenly. The lubricated bearings help cushion this impact load. Cleaning: High-quality engine oil carries away carbon deposits, sludge, and worn metal particles from engine parts back to the oil pan, flushing away contaminants through oil circulation. Precautions for Oil Change: Drain oil when hot for better fluidity; Fill to the dipstick mark; Choose oil change intervals based on vehicle condition, road conditions, oil quality, and driving habits; Select oil based on driving environment, frequency, and engine requirements—prefer higher quality over lower.
