Can I put 5w40 in my BMW?
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..
What happens if I put 5w20 instead of 5w30?
Probably not. 5w20 oil is fairly light oil and is generally designed to work with newer engines. Motor oil has become part of a manufacturers program to allow engines to get higher fuel mileage. Lighter oils take less HP to pump through an engine than heavier oils.
Is Thicker oil better for high mileage cars?
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 you put 10w 30 oil in a 5w30 engine?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
Can I use 5w30 instead of 5w40?
If you are racking your brain to choose between 5w30 and 5w40, we recommend you go with 5w30. However, if it is too expensive or not available for use, you can always go with the 5w40, which is just as good and will not cause any damage to the engine parts.
What does 5w 40 mean in oil?
5w40 engine 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.
What’s the best oil for BMW?
Best Motor Oils for BMWCastrol EDGE 5W-30 Advanced Full Synthetic Motor Oil. … Mobil 1 120760 Synthetic Motor Oil. … Motul 007250 8100 X-cess. … Pennzoil 550020166-6PK. … Genuine Synthetic 5W30 Motor Oil. … Valvoline Advanced Full Synthetic.
Does 10w40 hurt 5w30 engine?
The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.
What happens if I put 10w40 instead of 5w30?
If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
Which oil is thicker 10w40 or 5w30?
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.
Can I use 10w 40 instead of 5w40?
10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. … Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.
Do BMWs need special oil?
Modern BMW engines are designed for specifically formulated synthetic motor oils, unlike older engines that could use conventional motor oil.
Can I go from 5w30 to 10w40?
As posted above, mixing 5w30 with 10w40 will give you an oil that performs somewhat better in the cold than 10w40, but less good cold than 5w30, and that has a viscosity a bit higher than 5w30 but a bit lower than 10w40.
Which oil is thicker than 5w30?
5w30 is used for light-duty engines while 10w30 is used for engines which carry heavier loads. 10w30 provides sealing action in the engine due to the fact that it is thicker than 5w30 engine oil. Thinner at lower temperatures.
Which is thicker 5w40 or 10w40?
The main difference between the two oil types is that one is thinner than the other. The 5W40 is thinner than the 10W40 at lower temperatures. … On the other hand, the 10W40 motor oils are thicker than the 5W40 oils for good reasons. This oil type works pretty well in lubricating engine parts during startup.
Can you use 5w40 instead of 15w40?
Viscosity is a fluid’s resistance to flow. … Both will have a viscosity of a 40 grade. That cannot be said for both oils during the dead of winter. The 5W-40 will have a lower viscosity when the engine is started than the 15W-40; consequently the 5W-40 will start easier and lubricate quicker in the cold than the 15W-40.
Is Thicker oil better for older engines?
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.
What does 5w 30 oil mean?
multigrade oil5W-30 means that this is a multigrade oil. This is indicated by the two numbers separated by a “W” 5W – shows thickness/viscosity of the oil on a start-up – when you start the car (W – stands for Winter, this indicates oil performance under colder engine temperatures when the engine has not been running)
When should I use 5w30 oil?
Using these factors, the 5W30 is your go-to oil when you want something that has a thin enough viscosity for use in cold weather, wider working temperatures and is ideal for light-duty diesel or petrol vehicles.
Can I use any 5w30 oil in my car?
If your car takes 5w30 oil and you put 5w30 oil in it, it’ll be fine. Totally wrong, these days the spec compliance of an oil is often more important than the viscosity. Don’t put any 5w30 in, put the correct 5w30 in.
Is 5w40 good for summer?
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.
