It is related to the working condition of the engine ignition system and the electronic fuel injection system. The following are the specific reasons and solutions: 1. Abnormal ignition system: The ignition energy is too weak or there is intermittent misfiring. Solution: Replace with better-performing spark plugs. 2. Abnormal electronic fuel injection system: Low fuel pressure, clogged fuel filter, clogged or leaking fuel injectors causing poor fuel spray and atomization. Also, check if the air filter is severely clogged, as this can lead to insufficient air intake, resulting in an overly rich air-fuel mixture. Solution: Take it to a specialized repair shop for inspection and analysis. 3. Low cylinder pressure or clogged exhaust system: Solution: Take it to a specialized repair shop for inspection and analysis.

Can the Mistra use 0w20 engine oil?

The Mistra is not recommended to use 0w20 engine oil. The recommended engine oil specification for the Hyundai Mistra is 5w30, with a replacement capacity of 5L. It uses fully synthetic oil and has a replacement interval of 5,000 kilometers. Naturally aspirated engines have lower requirements for oil performance, so mineral oil or semi-synthetic oil can be used. If the consumer's budget allows, fully synthetic oil can be used. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the 'blood' of the car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil, imparting certain new properties, making them an important part of lubricating oil.
