CVS, primarily known as a retail pharmacy chain, offers a wide range of products, including over-the-counter medication, health and beauty items, food and beverages, and general merchandise. However, CVS does not specialize in automotive products, and as such, it does not typically sell engine oil. Customers looking for automotive supplies, including engine oil, would be better served at auto parts stores (like AutoZone or Advance Auto Parts), large supermarkets, or department stores that have an automotive section (such as Walmart or Target). These outlets specialize in or have dedicated sections for automotive needs and are likely to offer a variety of engine oils for different types of vehicles.

Yes, 2-stroke engines do use oil, but it's generally mixed with the fuel rather than being added separately like in a 4-stroke engine. This is because 2-stroke engines don't have a dedicated lubrication system, so the oil is burned along with the fuel during combustion.

1. To reset your check engine light. the simplest method is to remove the battery. Disconnecting the battery's negative terminal for a few minutes should do the trick. However. if the issue is severe or the light remains on immediately. this approach may not be effective.

No, electric vehicles (EVs) are generally better for the environment than traditional gas-powered cars.

1. Emission-free: EVs produce zero tailpipe emissions, reducing the amount of carbon dioxide and other pollutants released into the atmosphere.

2. Energy efficiency: Electric vehicles are 4-5 times more energy efficient than petrol/diesel cars. They convert a higher percentage of the electrical energy from the grid to power at the wheels.

3. Renewable energy integration: If charged from renewable sources like wind or solar power, emissions can be even lower.

4. Decrease dependency on fossil fuels: As electric cars run on electricity, they reduce the dependence on fossil fuels, leading to a decrease in greenhouse gas emissions.

However, there are two main environmental concerns related with EVs:

1. Battery production: Manufacturing the lithium-ion batteries commonly used in EVs can have a substantial environmental impact. The process is energy-intensive and involves the mining of rare earth metals, which can be damaging to local environments.

2. Electricity source: If the electricity used to charge EVs comes from coal-fired power plants, the overall environmental impact is higher, as burning coal for electricity produces large amounts of CO2 emissions.
Overall, the environmental impact of EVs is largely dependent on how the electricity they use is generated. As the energy grid becomes more sustainably focused, the benefits of electric vehicles will increase. Furthermore, innovation is leading to more sustainable battery options which are set to lessen the environmental impact of their production.
