Motor oils are graded based on their viscosity. 5w 20 and 5w 30 engine oils are commonly used in colder temperatures. However, they are recommended for older engines and light-duty use. This is because an oil with a higher rating indicates that it is thicker and suits well those engines which run hot easily.
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 type of oil should I use for my car?
You should always use the oil recommended by Solution Oil. However, 5w30 oil can operate in temperatures ranging from -30ºC to 35ºC, making it an ideal choice if you drive your car in a location with relatively high seasonal temperature fluctuations. 5w30 oil is particularly suitable for cars driving in cold climates.
Is high mileage engine oil a way to fix engine wear?
Just don’t think that high mileage engine oil is a way to fix engine wear. Both high mileage 5w30 and 10w30 engine oils have the same additives, the only difference is the viscosity at cold startups. Since both oils have the same operating temperature viscosity (30) and additives, they will perform exactly the same.
What is the difference between 0w40 and 5w40?
The longer it takes for the oil to pass through, the higher the SAE code is assigned due to the higher viscosity, which means the 5w40 has a higher viscosity than 5w30. Read more about the difference between 0w40 vs 5w40. More… Why Is Thickness Important? Why Is Thickness Important?
How often should you change oil in car?
And while the old rule of thumb was to change your oil every 3,000 miles or so, modern automotive technology has stretched that figure even further. Due to better engineering and better oil formulations, now you can expect between 7,500 to 10,000 miles between oil changes!
How many miles should an oil change last?
Let us simplify it for you. Conservative estimates for oil-change intervals used to be as low as 3000 miles, before significant improvements in fuel-delivery systems, engine materials, manufacturing methods, and oil chemistry. Today, modern engines driven normally stretch intervals to 7500 or even more than 10,000 miles.
What is the recommended synthetic oil change interval?
Manufacturers’ recommended synthetic-oil change intervals vary greatly. For the vehicles in Car and Driver’ s long-term test fleet, those intervals range from 6000 to 16,000 miles (and almost always include oil-filter changes).
Should I get an oil change?
A regular oil change service gives you a well-lubricated, cleaner engine, so you’re extending the life of the car and potentially reducing ongoing maintenance costs as well. Using old engine oil means your car’s emissions are likely to be dirtier than if you get a regular oil change done.
How often should you drive a car?
Every 10,000 to 15,000 miles or every six months (16,093 to 24,140 kilometers) Let’s take a look at the circumstances for each. First, if some experts say that 3,000 miles is too often, why would those same experts recommend intervals of every 1,000 miles? It all depends on your driving habits.

What engine oil do I need for my Vauxhall?
Some other common car models recommend 0W-30 oil, which is similar to 5W-30 but will be less viscous at lower temperatures. Certain Vauxhall Astra, Vauxhall Corsa and MINI Cooper models recommend this. Remember to check your handbook for your specific make and model, as the recommended oil can differ. What are engine oil specifications?
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 .
Do older cars need thicker oil?
Many older, high mileage engines might face issues with oil pressure due to age and wear and tear. In this case, a practical method to improve oil pressure is to use a thicker oil, since the thicker oils have heavier base weight oil, which can help protect worn engine bearings well.
Should I use thicker oil in an older engine?
As a lot of oil burning is taking place and adding thicker oil won’t fix your engine, it will even worsen the situation. But there are many types of thicker oil to use in an older engine. Let’s discuss should I use thicker oil in an older engine or not!
Should I put thicker winter weight oil in my car?
It would especially not do your engine any good to put the thicker winter weight oil into the vehicle (assuming you are gaining on winter where you are at). The thicker oil when cold will not flow as well as the 5w-30, which means your engine will remain oil starved longer at start up, causing it to achieve more wear. Not good all the way around.
Is it possible to increase oil pressure in an older engine?
Yes, because it is a feasible method to improve oil pressure in an older engine. Slightly more viscous oil will help you in protect worn bearings too. When heavier oil will be added to the engine, it will never leak and throw extra smoke out of the engine. Thicker oil can be the best motor oil for hot weather.
What engine oil should I use?
Therefore some mechanics recommend using engine oil that is one level thicker than the recommended engine oil for engines that are considered old. For example, if the recommended 5W-20, you can change to 10W-30. The viscosity of the oil is able to withstand large component clearances
What oil should I use in my older engine?
Monograde oils are still widely available, primarily because they’re used in very hot climates, or in heavy-duty applications such as mining or construction equipment. These single-grade oils can be used in 1950s and older cars – generally SAE 30 to SAE 50 – but most owners use multi-grade.
What is the best oil for an old engine?
Castrol Classic Oil is the perfect choice for your classic or vintage car. Older engines have very different requirements than modern engines. What oil is best for old engines?

What kind of oil do you use on a flat tappet engine?
If you have an older engine with flat tappets (generally pre-1980s), or certain performance modifications, you’ll need to treat them to oil with zinc dialkyldithiophosphate (ZDDP), which lubricates them and prevents premature wear to the camshaft. Zinc got phased out when cars didn’t need it anymore, since it can harm catalytic converters.
What kind of oil does a car run on?
Older cars ran on monograde or “straight-weight” oil, because that’s all there was. Multi-grade or multi-viscosity oils – such as 10W30, where the “W” stands for “winter, ” not “weight ,” as some think – arrived in the 1950s.
Should I use viscose oil in an older engine?
In fact, a slight viscose oil could be a better idea for older engines as it will also help protect weary bearings. It’s because when a thicker or heavier oil is added to an old engine, it throws extra smoke out of it without leaking the oil. So, should I use thicker oil in an older engine?
Can I use 10W 40 instead of 5W-30?

Can I use 10w40 instead of 5W-30?
A common question is whether it’s safe to use 10W-30 instead of 5W-30 oil, for example. While it’s best to use what’s recommended in your owner’s manual, inadvertently using a viscosity one grade higher or lower than what’s recommended generally poses no long-term harm.
What is the difference between 10W-40 and 5W-30 motor oil?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil. The second number in the motor oil’s name describes the viscosity of the oil when the engine is warm and the oil reaches operating temperature.
Can I run all 10W40?
Heck you can run all 10w40 if you like. You migth lose a little gas milage but that is all. No one quart will not do any “damage”. Heck you can run all 10w40 if you like. You migth lose a little gas milage but that is all. Thanks. I did seem to notice that. It felt a little… “sticky” and the gas light was on before we got it home.
Is the 5W30 bad in mileage?
However, the 5W30 is not bad in mileage either. It works excellent and provides the best mileage in colder temperatures. Which one to choose – 10W40 vs. 5W30? The answer is, choose the one that your user manual says. This is the best option that could ever be for your engine.
Should I use 5W or 10W oil?

Should I use a 10W oil instead of a 5W?
There is a small benefit of using a 10W instead of a 5W oil in that the 10W will normally have less viscosity improvers in it. Viscosity improvers help the oil behave “thicker” at higher temperatures, but they do not actually provide lubrication.
What does 5W mean in engine oil?
The first number (5W) refers to the oil’s viscosity when cold, measured at 40°C (104°F). “5W” refers to the oil’s viscosity when cold, measured at 40°C (104°F). It helps to think of the “W” as standing for “winter.” Lower numbers mean the oil will remain more fluid and easier to circulate throughout your engine for improved start-up protection.
What is the difference between 5W-30 and 10W-30?
When looking at 5W-30 vs 10W-30, they both provide the same viscosity at operating temperature, as indicated by their identical “30” ratings. Oil viscosity is the measure of its resistance to flow.
Is 5W-30 oil bad for your engine?
Using 5W-30 instead can reduce fuel economy and impede flow throughout the engine. While using it temporarily in a pinch likely won’t cause your engine lasting harm, remember that the engineers who built your engine did so with a specific viscosity oil in mind, meaning it’s best to stick with it.
Is it OK to use 10w30 instead of 5W-30?
You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperatures. Generally, the viscosity difference between the two is neglectable. However, it’s important to note that a 10w30 oil will move slower than a 5w30 oil in cold environments.
Is 5W-30 oil better than 10W-30?
The lower the oil’s “W” viscosity, the more readily it will flow when cold. In this case, 5W-30 will flow more easily at startup than 10W-30. In fact, some automakers allow you to switch to a lower viscosity oil depending on weather. Find the Right Viscosity Oil for Your Engine
Should I use 20w50 oil on my engine?
It’s important to note, that your engine’s oil pump, and thus the engine, has to work extremely hard to pump thicker oil and maintain oil pressure, so folks that would resort to 20w50 oil on their tired, old engine would also sacrifice horsepower using it.
Should I use 10W – 30 oil if it is cold?
However, the 10W – 30 oil will be thicker when it is cold. As per API recommendations (1) for car engines, you can use 10W – 30 oil if the maximum expected outside temperature is above -18°C (0°F). If you are living in an area where the outside temperature can go below zero; It is better to use 5W – 30.
What Acea rating should 10W30 engine oil have?

What is the difference between Mobil 1 5W-20 and 5W-40?
While Mobil 1 5W-20 has corresponding viscosities of 49.8 and 8.9. Clearly the 5W-40 is a MUCH thicker, denser, heavier oil (both full synthetics). Use the recommended viscosity for your particular application. You should only adjust those figures within the general approved range.
What does 5 and 40 mean in engine oil?
The 5 means that the oil will flow at zero celsius the same way a 5-weight oil would. The 20 and 40 mean that the oil will flow like a 20 and 40-weight respectively at engine operating temperature (180-195C usually). The actual viscosity of the oil is therefore the SECOND number. The first number just indicates how resistant it is to cold.
Is 5W-30 or 10w30 better for winter?
10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.
What is the difference between 10W-30 and 5W-30 oil?
5W-30 oil has a better low temperature viscosity grade as compared to, say, 10W-30 oil. As a result, the 5W-30 is less viscous in cold temperature settings. The low viscosity of this oil means it doesn’t thicken at a colder operating temperature and flows smoothly through the engine without causing friction.
Is 5W30 oil good for cold weather?
Having the lower viscosity rating makes the 5W30 oil an excellent choice for cold weather. This helps to ensure an easier start up and better lubrication in these extreme winter temperatures. The higher viscosity rating, 10W, of the 10W30 oil at a lower temperature means that it will thicken faster in cold weather.
Is 10W30 oil good for a high mileage engine?
10W30 oil can be good for a high-mileage engine. However, there are many more factors to consider before, and it is best to follow the manufacturer’s recommendations. However, many people prefer to use even thicker motor oils than 10W30 in high mileage engines.
Should I use 5W30 or 10W30 in December?
Agree with above post, but this is the wrong question to ask in December, unless you live in the Deep South or somewhere else warm. Most cars now recommend 5W30 for winter and optionally 10W30 for summer. If I lived in West Texas, I would use 10W30 in the summer and 5W30 in the winter.
