The type of oil recommended by the car manufacturer will be listed in the manual. It may recommend a particular brand, but the grade and ACEA specification are the important things to look for. Does brand matter? As long as the grade and ACEA specification is correct, you should be fine.
What are the different types of motor oil?
As you can see from our list, the three main types of motor oil are conventional oil, synthetic blends, and full synthetic engine oil. Conventional motor oil is made from crude oil and has been around for ages. It does a fine job of protecting your engine and it does so at a lower cost than synthetic oil and synthetic motor oil blends.
What is the best oil for a car engine?
This oil also helps condition seals to stop leaks and reduce oil consumption, which prevents engine damage. Older car engines often do better with a conventional motor oil rather than the newer synthetic or synthetic blends. If you want to keep it old school, then Castrol GTX is a great traditional motor oil option.
Are all oil brands interchangeable?
The answer is… they’re all interchangeable so long as they meet the oil weight and certifications for your vehicle. Mobil 1, Pennzoil, Valvoline, even the discounted brands such as Walmart’s Supertech and Peak will not wear your engine out any quicker than any other brand that meets the basic standards for your vehicle.
Is synthetic engine oil better than conventional?
Synthetics provide better cold weather protection through faster oil flow at start up. They also tend to resist breakdown better in high-heat situations, like summer or high-performance conditions. If you’re thorough and consistent about changing your oil on time, conventional motor oil will protect your engine.
Does engine oil expire?
Simply put, the shelf life of conventional motor or “lube” oil is up to five years. It’s not something that goes bad in a couple of months. It’s impossible to predict exactly how long motor oil shelf life is because petroleum stability (how well it resists change in its properties) is situation-dependent.
What is the expiration date of motor oil?
There is no official expiration date on oil like we get on food. However motor oil is the same as tyres, they will last for a long time however they go past there best after 5 years. Does motor oil go bad sitting in an engine? In the engine, the oil will start to degrade over time yes.
Does motor oil go bad?
Although you can look at the expiration dates on the bottle, motor oil can also go bad just from sitting in a car engine for too long or when stored improperly. Under optimal conditions, motor oil should remain fairly stable. However, extreme temperatures, synthetic additives and oxidation all play a role in causing it to go bad.
How long does an unopened motor oil bottle last?
An unopened motor oil bottle lasts for approximately 5 years, or until the expiration date on the bottle expires. If the oil is already in the engine, you should follow the manufacturer’s schedule for how often it should be changed. It is usually every year or every two years. 1. Unopened on Shelf
What does unused engine oil mean?
Unused engine oil refers to motor oil that has not been used in an engine. The biggest indicator that your unused motor oil is bad is the expiry date. Unused motor oil will start to degrade and lose its effectiveness after a certain amount of time. Most engine oils will have an expiry date printed on the bottle.
Can I put any oil in my car?
You can add any engine oil as long as it has the right specifications — preferably with an official approval of the OEM (Original Equipment Manufacturer). Not the brand, but the specification and viscosity indicated in your car’s manual are your reference for using the right oil.
Should I add oil to my car?
While all vehicles are a little different, adding oil is something anyone can do with a little eye for detail and a willingness to get dirty. Adding oil, however, is not a substitute for getting your oil changed. Check oil after the car rests for 5 minutes by popping the hood and pulling out the car’s dipstick.
How do I choose the right engine oil?
It is important to choose the right engine oil for your car. The wrong oil can cause damage to your engine and may void your warranty. Check your owner’s manual or the oil label on your car to find the recommended oil type and weight. There is a very fine line between what you want the oil for and what you should use it for.
Can you put synthetic oil in an old car?
Yes, You Can Put Synthetic Oil in a Classic or Just Plain Old Car It protects better, performs better, and lasts longer, and it’s no longer made with a chemical compound that could hurt older vehicles.
How much oil should I put in my car?
too low: if the level falls below the lowest marking, it’s time to add more oil (see below). how much oil does my car need? motor oil is definitely not one-size-fits-all. figuring out how much oil your car holds will require you to read your owner’s manual. if your check indicates you have low oil, you’ll want to add half a quart at a time.
Is all oil the same quality?
When it comes to choosing engine oil for your car, you might think “it’s just oil, surely they’re all the same?” Not only are there different types of oil, but they also differ in viscosity and additives which can have a significant impact on the performance and life of your engine.
Is all crude oil the same?
Not all crude oil is the same. Just as there are different types of crude oil derivatives — diesel, gasoline, kerosene (jet fuel), fuel oil, bunker fuel, plastics, synthetics, cosmetics, household products, etc., — there are different kinds of crude oil.
Why are crude oil from different locations of higher and lower quality?
The reason crude oils from different locations are of higher and lower quality is that of the geologic process that produces crude oil. Sulfur content and weight are the two qualities by which crude oil is typically judged. High-sulfur, heavy oils are the lowest quality and the least expensive on the global market.
What are the characteristics of crude oil?
Crude oils have different quality characteristics. Crude oils that are light (higher degrees of API gravity, or lower density) and sweet (low sulfur content) are usually priced higher than heavy, sour crude oils. This is partly because gasoline and diesel fuel, which typically sell at a significant premium to residual fuel oil and other “bottom…
What is the difference between synthetic and conventional engine oil?
As motor oil circulates through your vehicle’s engine, deposits form. Conventional oils form sludge from these deposits over time, reducing your engine’s efficiency and lifespan. Full synthetic oils, by contrast, contain fewer impurities and resist sludge and deposit formation.

We do recommend Castrol or Liqui Moly for most engine types. Will synthetic oil last 2 years? The most so-called “long-life” synthetic motor oils last up to 2 years or even longer.
What is the longest lasting motor oil?
The new synthetic oils are the longest lasting motor oils, but some last for longer than others. You should be able to find this information right on the bottle. Your next longest lasting oils are synthetic blends followed by conventional motor oil.
Which oil is best for my car?
Choose an oil with the vehicle manufacture’s recommended viscosity rating (check your owner’s manual). Viscosity is an oil’s ability to flow at different temperatures. The two most common viscosities (a.k.a. weights) are SAE 5W-30 and SAE 10W-30. The lower the number, the thinner the oil.
Is Castrol a good engine oil?
If you’re looking for a reliable synthetic motor oil, then Castrol has you covered. This affordable synthetic engine oil option is designed to reduce engine wear leaving engine parts up to four times smoother through molecules that stick to the engine.
Is all 5W-30 oil the same?
5w30 is a motor oil that is widely used in light-duty petrol and diesel engines. Like most motor oils produced today, 5w30 is a multi-grade oil, meaning it ranges from a lower viscosity grade of 5 to a higher viscosity grade of 30.
Is 5W-30 the same as 5W-20?
5W-30 is also rated 5W in winter conditions, with an SAE grade of 30 when the engine’s warmed up and you’re driving. This oil behaves the same as 5W-20 in the cold. However, it becomes comparatively thicker when flowing under standard running temperatures. For a long time, 5W-30 was the most common motor oil.
Is 5W-30 oil good for car engine?
5W-30 oil is unsuitable for extremely high temperature use since, at these temperatures, car engines require a thicker oil with proper bearing support and cushioning. As 5W-30 oil is comparatively thinner than any other multigrade oil like 5W-40, it may not lubricate the engine well. 2. Is 5W-30 Oil Suited For Heavy-Duty Use?
What is the best engine oil for my car?
The ideal engine oil for your vehicle is one that sustains its viscosity and grade, even in the hottest temperatures as well as in the coldest temperature situations. 5w30 oil is suited to a broad range of temperatures, making it one of the most commonly used oils on the market.
What does W mean in engine oil?
The ‘ W ’ stands for winter. The numbers after the W stand for the oil viscosity rating at high temperature (212°F). The higher this number, the better resistance the oil will have against thinning at a high temperature. What Is 5W-30 Oil Good For? 5W-30 oil is primarily a winter viscosity grade motor oil .
Does wrong engine oil matter?
Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so. Contrary to what some believe, adding synthetic oil to regular oil won’t harm the engine, but there’s also no benefit in doing so.
What happens if you use the wrong engine oil?
Engine Damage: Using the wrong type of engine oil can cause substantial damage to the engine. Using too high viscosity oil can result in the oil losing its cohesive strength and not being as lubricating as it should be. This will also result in burning of mobil oil and cause long-term damage to the components.
What happens if your engine oil is too thick?
What this means is that if the motor oil in your car’s engine is too thick, it will not be able to properly lubricate the components of the engine properly, causing excess resistance when you start the car.
Why is my engine not lubricating properly?
This happens because the wrong weight of engine oil can do a poor job of coating and lubricating all engine components. What you are hearing is metal components such as valves and valve lifters hitting against other metal. Temporarily switching to a different oil viscosity may cure the problem.
What happens if you mix too much oil?
Using too thick of an oil can result in high oil pressure in some cases. While it’s not recommended to mix various brands (example: Valvoline, Castrol, Mobil 1, Amsoil, etc.) of oil, it won’t cause damage to your engine. What matters more is sticking with the same oil viscosity.
Does different oil make a difference?
Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can’t compete with the overall engine performance and protection provided by synthetics.
What’s the difference between synthetic oil and mineral oil?
It’s hard to find any info that’s not just marketing garbage. Most oils have proprietary additives.Mineral based oils contain sulphates that can be damaging to “yellow metals” i.e. copper and brass etc… (an issue with gearboxes) Synthetic oils generally do not.Follow vehicle makers specifications.
Is it better to use cheap oil or quality oil?
Repair Savings Taking care of a vehicle by using quality oil will save money in the long run, even though these lubricants are more costly.

What is engine oil and why is it in my engine?
Dan has been an auto mechanic, truck driver, engineer, and many other things. What Is Oil and Why Is It in My Engine? Oil is the substance that lubricates the internal moving components of your vehicle’s engine.
Is higher viscosity oil better?
A higher-viscosity oil will withstand more heat than a lower-viscosity oil. However, at colder temperatures, it can actually become so thick that your starter cannot turn over the engine—and worse yet, it won’t flow to all the moving parts it should.
Is all car oil the same?
Engine oils aren’t all the same. You can’t assume that the same oil you used for your last car will work for this one. So if you need to top-up, make sure you use the right grade and specification.
Is engine oil the same as motor oil?
This is a notable point to consider when choosing oil for your car, as it plays an essential role in your engine performance and longevity. Get this clear – engine oil and motor oil are the same doesn’t mean all oils are the same. Both engine and motor oil are the same, but they have various types.
Which type of motor oil is best?
Generally speaking, Group IV base oils offer the best performance, Group III second best, and so on in reverse order. But be forewarned – there are exceptions. And, you can’t judge motor oil performance solely on base oil type. You must take into account its entire formulation, including the additives.
Can you mix different motor oil brands?
All API-certified oils should be compatible, and each motor oil will comprise a base compound and several additives that form the product base and other qualities that make each oil unique. Therefore, you can safely mix one motor oil brand (e.g. Castro) with a different brand (e.g. Valvoline). You can also mix synthetic oil with conventional oil.
