Most car engines are designed to handle 5w20 oil because this type of oil flows well when the engine reaches its operating temperature of 212 degrees. If 5w30 oil is used, the engine will encounter much more resistance at this stage which is not good for it.
Here`s the rundown for our purposes here: In a pinch, while it`s generally OK to use an oil that`s one viscosity rating higher or lower than what the manufacturer recommends, it`s best to use the viscosity given in the owner`s manual. When considering 5W-20 vs 5W-30, they are the same viscosity when the engine is cold.
6 Liters Of German RAVENOL DXG 5w30 Motor Oil – Meets the Chrysler MS-6395 motor oil quality standard and viscosity required for the 3.6L Chrysler 300 engine.
When it comes to their higher operating temperature performance, 5W30 motor oil performs slightly better than 5W-20 and is a thicker oil than its counterpart. 5W30 motor oil would be more robust and not break down very easily at a higher temperature.
The 5W-20 will remain a little thinner at operating temperature, as indicated by its lower “20” number, while 5W-30 will provide a slightly thicker lubricating film. When looking at 5W-30 vs 10W-30, they both provide the same viscosity at operating temperature, as indicated by their identical “30” ratings.
The wrong engine oil can cause engine damage because it does not properly lubricate its components. This will lead to metal-on-metal contact since the moving parts are not being lubricated. Friction quickly follows, causing engine parts to wear.
5w30 can be used by different types of vehicles and in various ranges of temperatures, but are generally ideal for colder temperatures. 5w40 on the other hand is often used in higher mileage engines and they will perform the better of the two in warmer temperatures.

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.
Pennzoil High Mileage SAE 5W-30 Motor Oil is engineered for cars that have accumulated more than 75,000 miles, particularly those that are experiencing oil leaks and oil burn off. Engines with higher mileage tend to experience more wear than new engines.
5w30 oil is particularly well suited for cars driven in cold climates. Unlike oils with a higher hot temperature rating such as 10 or 15, 5w30 oil can flow freely enough when the engine is started at low temperatures to coat and protect the engine`s internal components.
In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.
5W30 and 10W30 motor oil are pretty similar in their performance at operating temperature. But when it comes to low-temperature performance, 5W-30 oil performs better because of its low viscosity in a colder climate.
5W-30 oil is the lead viscosity recommendation by automakers over the past four decades for use in many vehicle types – passenger cars, SUVs, light vans and trucks – including those with high-performance turbo-charged and supercharged engines.
Today, the most common grade is 5W-30 because it is suitable for various vehicles and engine types. On the back of an engine oil container, there should be a list of specifications the product meets to ensure you choose the highest quality oil for your car.
Thicker oil may not flow quickly enough

Its lower viscosity allows it to flow faster and fill the tiny clearances between parts, leading to a durable, consistent lubricating film. Not only that, but the engine will waste energy pumping the thicker oil, reducing fuel economy.

It`s best to use the oil viscosity recommended in the owner`s manual, but using a slightly thinner or thicker oil (lighter or heavier viscosity) generally poses no long-term harm.
5W-20 engine oil can be a great choice for your car. It offers a decent operating temperature range, improves fuel efficiency and engine protection in colder climates, and boosts fuel economy. The important thing to remember is to get a routine oil change and perform regular maintenance.
The thinner nature of 5W-20 oil also allows the oil pump to move it from the oil pan to the rest of the engine more easily. This makes 5W-20 preferable for very cold climates, when having thinner oil that can flow easily on start-up is important.
5W-20 is a comparatively thicker viscosity oil and is better for a normal operating temperature range of -22°F to 68°F.
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.
Thanks to their close viscosity, mixing the two oils will have no damaging effect on the engine. It`s worth remembering that 10W-30 has more density than 5W-30, so make sure you pour an appropriate amount when mixing.

the most relevant questions and answers related to your specific issue

Can i use 5w30 motor oil instead of 5w20 for my 2008 ford fusion?
ANSWER : Ford specifies only one viscosity rating for this vehicle, namely SAE 5W-20. In that specification, which is contained in the Owner’s Manual, Ford states: "5W-20
oil provides optimum fuel economy and durability performance meeting all requirements for your vehicle’s engine." For sure, fuel economy will be degraded if you use the higher (30 weight) viscosity. But, the statement from Ford also implies that use of oil other than 5W-20, such as 5W-30, will reduce the service life ("durability") of the engine. Consequently, I would stick with the 5W-20. Synthetic oil is much preferred, of course. YourMechanic does offer mobile oil and filter changes. If you desire that service, please request an oil/filter change and the responding certified mechanic will perform that for you right at your location. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

lost all oil pressure, replaced the oil pump, low oil sensor, oil pressure sensor, oil pan gasket,
ANSWER : The fuel pump will not stay on if you loose oil pressure. This is why it is shutting off. The loss of oil pressure may be from bad crankshaft bearings or camshaft bearings. The engine oil pan should be removed and the oil pump needs to be checked to ensure that you put in the pick up tube seal to the pump and connected the pump to the block. Then remove at least one main bearing cap and inspect the bearings for excessive wear and crankshaft damage. If you need some help with this, consider YourMechanic, as a certified technician can help diagnose the issue with your oil pressure firsthand and help you fix it accordingly.

I just used semi synthetic oil instead of full synthetic in my 1996 lincoln town car executive
ANSWER : Hi there. If you asked this question about 10 years ago – then yes, you might have issues with seals or gaskets wearing prematurely. However, as technology has improved, the gap between semi-synthetic and full synthetic is not as big. You should be just fine without having problems.

Oil consumption. Burning oil. Oil light turns up on idle.
ANSWER : Hi there, thanks for writing in. The valve stem seals are the most common cause of this on your engine. When they fail, it requires that the cylinder heads be removed and rebuilt to fix it. The piston rings can also cause this but they are not as common. Unfortunately there is not anything, not even heavier oil that will fix this. You will need to have the heads rebuilt.

I got a Patrol vehicle, Chevrolet Impala that calls for 5w30 motor oil. Can I use 5w20 if necessary?
ANSWER : Hi there. If you’re in dire straits to find the right type of oil, using a small amount of 5 w 20 should not hurt your vehicle; especially during colder times during the year. The 5 is the low end of the viscosity rating, while the 30 or 20 is the high end. During hot weather conditions, the thicker oil is critical for keeping the engine components properly lubricated. However, this should not be a normal thing you do; so have your oil changed as soon as possible to avoid potential issues.

Stop car check oil warning
ANSWER : This light will usually come on when one of two things are happening. Either the motor is in fact low on oil or the oil pressure sending unit is not working properly and may be producing a faulty reading. I would recommend first, to check the actual oil level in the motor by using the dipstick. Be sure the oil level reaches the "full" mark. If this registers as "full" then you likely have a faulty oil pressure sending unit. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to determine what may be causing your low oil pressure light to come on.

Advice on which weight of oil to use
ANSWER : Your car calls for 10w30 oil. The 10w is the winter grade that is blended with the 30 weight oil. The oil 5w30 will be a good replacement and should be compatible with your car. I would not go to a heaver weight oil or engine damage may happen since the thicker oil may not make it to lubricate all the tight parts like the thinner oil can.
