What are the consequences of using poor-quality engine oil in a car?
1 Answers
Using poor-quality engine oil in a car may lead to decreased power, increased fuel consumption, and damage to components such as the three-way catalytic converter. Below are detailed methods for determining the quality of engine oil: 1. Check the packaging: The caps on branded engine oils are generally one-time use and feature the manufacturer's special markings. 2. Smell the oil: High-quality engine oil, being fully synthetic, has a relatively aromatic smell. If the oil has a noticeable sour odor, it indicates that the oil has deteriorated. 3. Test the fluidity: Good engine oil has excellent fluidity, while poor-quality engine oil will produce bubbles when shaken vigorously.
