0W40 is better if you are living at a place where ambient temperature is high. If you are living at a place where ambient temperature is average then 0W40 and 0W20 will not make much of a diffrence. The viscosity of oil depends on the lower number 0 in your case.
When it gets hot it's entirely different, the 5W30 would do a better job because of it's thick viscosity, it will take more time for it to get thinner than the 0W40 that is thinner. Though both would work very well in Africa, but the 5W30 would do a better job in Africa and the 0W40 will deliver more in Europe.
5W30: Again from the combination of the numbers and alphabet, it show that the viscosity (5W) is higher relative to that of 0W40, therefore it is thick an not thin. The 30 in the 5W30 means that the motor oil will drop within certain viscosity limit at 100oC.
The numbers which appear after the W shows the motor oil's possibility of thinning when it has reached hot and rising temperatures. Therefore, when it comes to thinning out, the 0w40 motor oil stands a better chance of lasting than the 0w30 which would simply thin out in such hot weather.
Actually any good synthetic motor oil in 5W OR 10W40 WILL WORK FINE IN YOUR SRT.
A 0W-40 oil is a much better alternative than a 10W-40 oil. The second number is the tested viscosity rating at operating temps (ignoring the precise testing parameters). It is the significant number for your ambient temperatures and engine operating parameters.
0w40 is multi-grade oil that works well in winter conditions and moderate summer heat. The number 0 indicates how thick it is in winter, an ideal level for effortless flow.
Q: Is Mobil 1 a fully synthetic oil? A: Yes, it's 100% synthetic. A: All motor oils contain additives that provide extra protection against wear, corrosion and engine deposits.
It actually stands for Winter. That's because 0W-40 engine oil is formulated to flow like a 0 Weight oil in cold conditions, yet offer the protection of a 40 Weight motor oil when the engine reaches its full operating temperature.

Many automakers have oil-change intervals at 7,500 or even 10,000 miles and 6 or 12 months for time. Even if you drive fewer miles each year than your automaker suggests changing the oil (say, 6,000 miles, with suggested oil-change intervals at 7,500 miles), you should still be getting that oil changed twice a year.
Complete Engine Failure – If you go long enough without an oil change, it could cost you a car. Once the motor oil becomes sludge, it no longer removes heat from the engine. This can lead to a complete engine shutdown that will require a brand new engine – or a new ride – to fix.
Full synthetic oils will actually last well beyond 10,000 miles. The lifespan of synthetic oil depends, but it's not crazy to see oils still working at 15,000 miles or longer. Our standard recommendation is 7,500 miles for a normal vehicle based on the thousands of engine repairs we've seen over the years.
Go long enough without an oil change, and it could eventually cost you your car. Once motor oil becomes sludge, it no longer draws heat from the engine. The engine might overheat and either blow a gasket or seize up. If the heat doesn't cause a gasket to blow, it will warp the parts in your engine.
For those who drive only 6,000 miles or less per year, Calkins said manufacturers typically recommend changing the oil once a year. Moisture and other contaminants can build up in the oil, especially with frequent cold starts and short trips, so owners shouldn't let it go more than a year.
The quick-lube chains usually recommend it be done every three months or 3,000 miles, but many mechanics would tell you that such frequent changes are overkill. Indeed, most car owner's manuals recommend changing out the oil less frequently, usually after 5,000 or 7,500 miles.
However, car experts now say that the standard oil change interval of every three months — or every 3,000 miles (4,828 kilometers) — is old news, and that most cars can travel quite a bit farther before needing the oil replaced. Every 1,000 miles (1,609 kilometers) or every six months.
Can You Use Regular Oil after Synthetic Oil? Both synthetic and regular oil has the same application, and thus you can use regular oil after synthetic oil. Both regular and synthetic oils are made with lubricants to keep a vehicle's engine performance steady and smooth.
If you are using synthetic oil, the interval between oil changes can be extended. Manufacturer recommendations range from 5,000 miles to 7,500 miles, on average. Some recommended intervals might be shorter or longer.
You can but either oil will work. If your winters are brutally cold I would use 0w-40 year round. If your engine runs a bit warm use 5W-40. I run 5W-40 in my vr6 corrado and 0W-40 in my 330ci year round.
Re: okay to mix 5W40 and 0W40? (. It will be fine.
Re: Difference between 0w40 and 15w400w40 has a large viscosity spread, 15w40 does not. That's why 15w40 has always been a proven oil in HD applications. You're subtracting the difference between the two numbers. The larger the difference, the more viscosity improvers are used for a given oil type that can/will shear.
The Castrol oil that BMW used to spec was midway between a 30 and 40 weight. Anything from 0W30 to 5W40 will be fine if it has the LL-98 or LL-01 rating. You don't even need that if you are running shorter change intervals.
You would not be changing the oil to 5W40 if you had another change coming up in 2 days. If your engine is designed for 0W20 oil, this is extremely thin oil, so you might have problems in sub-zero temperatures, but generally and if the weather is warm it will make very little difference topping up with a pint.
