As a rule of thumb, 20W40 oil is fine for most petrol cars. The main thing to keep in mind is that the lower the “W” number, the thinner the oil will be at low temperatures. This means that 20W40 oil will be slightly thicker than other oils when your car is first started up, but it will quickly thin out once the engine is up to temperature.
If you live in a particularly cold climate, you may want to consider using a slightly thinner oil, such as 10W40 or 5W30. However, 20W40 oil will still flow freely even in very cold temperatures, so it’s not a bad choice for most drivers.
Types of engine oil and their uses
Motor oil is a lubricant that is used in internal combustion engines to reduce wear and friction. There are many different types of motor oil, each with its own set of benefits.
- Conventional motor oil is the most common type of motor oil. It is made from petroleum and is designed to protect your engine against wear and tear.
- Synthetic motor oil is made from synthetic materials and is designed to provide better protection for your engine than conventional motor oil.
- High mileage motor oil is designed for engines with more than 75,000 miles. It contains special additives that help to reduce wear and tear.
- Diesel motor oil is designed for diesel engines. It has a higher viscosity than conventional motor oil and contains additives that protect diesel engines from wear and tear.
- Racing motor oil is designed for high-performance engines. It has a higher viscosity than conventional motor oil and contains additives that protect engines from wear and tear.
Each type of motor oil has its own set of benefits. Choose the type of motor oil that is best for your engine based on your driving habits and the conditions in which you typically drive.
How to choose the right engine oil for your car
When it comes to engine oil, there are a lot of choices on the market. How do you choose the right one for your car?
The first step is to figure out what type of engine oil your car needs. There are three types: conventional, synthetic, and blends. Conventional oil is the most common type; it’s made from crude oil and it’s what most cars take. Synthetic oil is a synthetic version of conventional oil; it’s designed to last longer and protect your engine better in extreme conditions. Blends are a mix of the two types.
The next step is to check your car’s owner’s manual. It will tell you what type and weight of oil your car needs. Weight is important because it refers to the thickness of the oil. The thicker the oil, the better it will protect your engine in cold weather.
Once you know what type and weight of oil your car needs, you can start looking at brands. There are a lot of different brands on the market, and they all have different qualities. Do your research and find one that fits your needs.
When you’re ready to buy, make sure you get the right size. The oil comes in different weights, and you need to get the weight that matches your car’s requirements.
Once you’ve got all of that figured out, it’s time to start changing your oil! Changing your oil is a simple process, and it’s something you can do yourself. All you need is an oil filter, some oil, and a wrench.
Changing your car’s oil is important for keeping your engine running smoothly. By following these steps, you can make sure you’re using the right type and brand of oil for your car.
Engine oil is one of the most important fluids in your car. It protects your engine from wear and tear, helps it run cooler, and prevents corrosion. Different types of engine oil are designed for different purposes so it’s important to choose the right type for your car. You can use 20W40 oil in a petrol car but you may not get the best results. We hope this article has helped you understand more about engine oils and how to choose the right one for your vehicle.
