When comparing 5w20 vs. 5w30 motor oil, the 20 indicates that the oil has a lower viscosity and is thinner at higher temperatures. … So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures.
Can You Use 5W-30 Instead of 5W-20? In theory, yes, you can switch from using 5W-20 to the 5W-30 because they have similar viscosity ratings. In fact, often, when you take your car to a mechanic for an oil change, they’ll put the 30 instead of the 20 because it’s thicker.
The thicker 5W-30 should see a slight advantage when operating at higher temperatures, while the thinner 5W-20 oil should provide better engine protection at lower temperature levels and has the added benefit of slightly improving fuel efficiency.
To answer your question: Swapping 5w20 for 5w30 would *not* be a good idea. If the manufacturer of your car doesn’t spec 5W20 oil then you shouldn’t use it. The oil will be too thin (the smaller the number the “thinner” the oil) to provide the needed protection for your engine.
This ability to function well both in summer and winter brings with it the convenience of not having to change oil weights with the seasons. 5w30 oil’s lower viscosity also means less strain on the oil pump, as well as better fuel economy.
Theres nothing wrong with using 5w-20 in the summer, in fact 5w-30 wouldn’t be any better, remember that the “w” stands for “weather”. Unless your pulling trailer or a heavy load, you’ll be just fine.
5W20 motor oil is another low-temperature grade typically recommended for winter use, with a 10W-30 as an alternative for higher temperatures. This oil type is common because it provides the best fuel economy, saves fuel consumption, and has fewer exhaust emissions.
5W30 is perfectly fine. In fact according to the 2014 CRV 2.4L Owner’s Manual in Japan 0W20 and 5W30 are both recommended grades of oil.
It’s perfectly safe, most 5w30 will shear down to a 20w over time anyways.
When comparing 5w20 vs. 5w30 motor oil, the 20 indicates that the oil has a lower viscosity and is thinner at higher temperatures. … So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures.
5w30 motor oil has a winter viscosity grade of five, meaning it’s less viscous (less thick) at very low temperatures compared to, say, 10w30. It has a hot viscosity grade of 30, which means it is less viscous at high temperatures than an oil such as 5w50.
As you have likely now concluded, 5W20 is better suited for colder temperatures. If you need motor oil for summertime performance, 5W30 is going to be the better bet. However, you should only switch to this oil type of your car manufacturer or personal mechanic recommend doing so.
Is 5w20 good for hot weather? 5w-20will not necessarily break down faster, it will justhave a lower viscosity when it’s hot. Synthetic oil will take longer to break down, and you can get it in 5W-20 or 30.
The lower the W number, the better the oil will perform in colder temperatures. Typically, a 5W oil is recommended for winter use, but synthetic oils can be formulated to flow even more easily when cold.
The higher the number, the higher the viscosity. So 5w30 motor oil will be thicker at operating temperatures than 5w20 motor oil will.
SAE stands for Society of Automotive Engineers . They made #W-## oil grade system. 5W-20 and SAE 5W-20 are the same thing.
A synthetic blend oil.
If you add 5w30 to your vehicle instead of 0w20, the performance of your vehicle will not affect much. Your vehicle will continue to run smoothly and providing you comfortable rides.
Just do it in your own engine. And to the person who wanted to know if it was “safe” to use Mobil-1 5W-30 in your engine – As long as you really are using Mobil-1 5W-30… yes, it’s safe.
Don’t worry about it, change it and the filter again at 5-8K miles and you should be fine. The only viscosity difference between those oils will be a quite cold temps ~0F or there abouts. If you don’t see much of those temps, don’t worry.

There are a full range of Mobil-branded engine oils suitable for Honda cars with either gasoline or hybrid engines, including the Honda Civic, AR-V and Honda Accord models. It is important to use the right oil in your car to comply with Honda’s manufacturer specifications.
For Honda Accords made in 2011 or later, Honda recommends 0W-20 motor oil. These are the top picks, in order: Mobil 1 Extended Performance Full-Synthetic 0W-20. Castrol Edge Advanced Full-Synthetic 0W-20.
So to answer your question, no. Changing your own oil is not cheaper (unless you drive a Bugatti). If anything, it’s more expensive. But the little details like knowing exactly what’s in your car, and the pride of knowing you did it yourself, makes DIY oil changes worth the time, money, and overall struggle.
Newer vehicles can utilize thinner oils for faster lubrication of new engine parts. In contrast, older, high-mileage engines benefit from thicker oils to prevent friction and oil loss.
Oil weight, or viscosity, refers to how thick or thin the oil is. … Your engine needs oil that is thin enough for cold starts, and thick enough when the engine is hot. Since oil gets thinner when heated, and thicker when cooled, most of us use what are called multi-grade, or multi-viscosity oils.
here’s an example: 5w-20. 5: this is the oil’s viscosity rating at low or winter temperatures. w: this stands for “winter,” and is part of the “5” rating. 20: this is the oil’s viscosity rating at high temperatures.
Modern cars are designed to use lower viscosity oil ranges, so they can properly lubricate ( see attachment) Going from 5w-20 to 10w-30 should cause no harm for one oil change.
PETROFLO 0w-20 and 5w-20 SYNTHETIC MOTOR OIL protects engines up to 204°C (400° F.). It contains fewer impurities, so it protects better than conventional oils in cold weather.
The difference is in the viscosity of each at different temperatures. The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.
It is same as the case of these two oils; the 5W-30 is thicker than the 0W-30 motor oil. It’s the viscosity or “flowability” or thinness of any oil that determines it’s fuel economy improvement capacity. The 0W-30 is thinner or less viscous than the 5W-30 which makes it considered as better for saving more.
