Although both have the same viscosity grade in cold weather, 5W-40 is thicker than 5W-30 at warmer temperatures. It’s also worth pointing out that: 5W-40 is the suggested oil for most diesel applications. Rarely (if ever) do vehicle manufacturers recommend putting 5W-40 oil in a gas-powered engine.

The best engine oil for BMW 1 Series is 5W30 synthetic grade oil.
Should I use 5W-30 or 5w40?
5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.
What oil should I put in my diesel BMW?
Mobil 1™ ESP LV 0W-30 is a fully synthetic low ash oil that has been approved by BMW Longlife-12 FE oils for use in petrol and diesel engines in Europe.
Can I use 5w40 instead of 5W-30?
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.
Can I use 10W40 instead of 5w30?
What will happen if I put 10W40 instead of 5w30? Being a thicker oil 10W40 can harm your engine if your engine requires a thinner oil. Although a bit of interchange in engine oils can be good, it is highly recommended not to use one to replace another.
What does 5W 40 oil mean?
5w40 motor oil has a winter viscosity grade of five, meaning it’s less viscous at very low temperatures, compared to, say, 10w40. It has a hot viscosity grade of 40, which means it is just as viscous as 10w40 at high temperatures but less viscous than oils such as 15w50.
Is 5W40 good for diesel engines?
With a diesel truck, you will need a type of oil called 5w40. It is a more stable and less viscous oil that is specifically designed for diesel engines. It will help your engine work at the optimal temperature, which in turn will give you better performance and reduce engine wear.
Will 5W40 increase oil pressure?
However, as it warms up, the 40 oil will get thicker and more viscous relative to the 30. This will, increase oil pressure and the work that oil pump has to do.
Can I use any 5W-30 oil in my BMW?
Oil for BMW’s must have an API rating of SM or higher; your recommended SAE grade* will vary based on climate. A few of the recommended oils for your 2007 BMW include Mobil 1 SAE 0W-40 and Valvoline SynPower SAE 5W-30. If you live in a cold weather climate, the use of the 0W-40 is best.
Can I put 5w40 in my BMW?
BMW says you can use an: 0w40, 0w30, 5w30 or a 5w40 LL-1 oil in the USA.
Is Castrol 5W-30 good for BMW?
The change of preferred oil manufacturer came as a shock, mostly for the owners of the M50 family of BMW engines. Castrol Genuine 5W30 fully synthetic oil was the go-to pick for these motors. All the information available shows that the M50 family of engines loved this stuff to a fault.
What happens if I mix 5W30 and 5w40?
It won’t cause any adverse effect on your engine. However, as much as possible, use the same motor oil brand. Moreover, mixing the two will produce a new viscosity that is not the same as intended by the manufacturer so it’s best to change to the correct viscosity as soon as possible.
Is 5w40 good for high mileage?
RAVENOL SVS Standard Viscosity Synto Oil SAE 5W-40 is perfectly suited for year-round use in high mileage petrol and diesel engines with 100,000 km and more, and promotes low oil consumption. A very clean engine is guaranteed.
Does it matter what 5W30 oil I use?
In short: Every manufacturer has its own engines with its own specifications. As a result, every engine needs its own specific 5W30 oil. However, some 5W30 oils can be used for multiple brands.
What happens if engine oil is too thick?
If the oil is too thick (aka, the viscosity is high), your car may not start in cold temperatures (cold weather places more strain on a vehicle in any case). When this happens, the thick liquid can’t properly lubricate every part, and it creates enough resistance to impair the most important function–ignition.
Which oil is better 5w30 or 10w40?
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.
Is it better to use thicker oil in high mileage engine?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil — 10W — can help protect worn engine bearings as well.
Can I use 10w 40 instead of 5W40?
The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). If your motorcycle requires a 10W40 engine oil, there is no need to go for 5W40 oil. The 10W40 will just work well with your motorbike.
Is 5W40 fully synthetic?
Full synthetic 5W-40 motor oil is formulated to flow like 5 Weight oil from a cold start in winter temperatures and like 40 Weight oil once the engine has reached its normal operating temperature.
Can I use 15w40 instead of 5W40?
15w40 can be used in the temperature range of -20 °C or -4 °F and +40 °C or 104 °F, on the other hand, 5w40 is used between -30 °C or -22 °F and +40 °C or 104 °F. So, we can say that 15w40 is better in a warmer environment and 5w40 does a better job in a colder climate.
Is 5w30 OK for diesel?
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.
Which oil is best for diesel engines?
If you’re looking for the best oil for your diesel engine, you can’t go wrong with synthetic oil. Synthetic oil is designed to withstand extreme temperatures and conditions, making it ideal for use in diesel engines. It also provides superior protection against wear and tear, helping to extend the life of your engine.
Can I use 5w 20 instead of 5w30?
It’s not recommended to use 5w20 instead of 5w30 engine oil because Both come with different viscosity. 5w20 oil is thinner and mostly designed for performing better with newer engines.
What is 5W-40 motor oil used for?
