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..

Which is better 5w30 or 5w40?
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 temperatures of 50°C, as opposed to 30°C.
Is 10w40 good for summer?
However, if you live in warmer or hotter regions, you’d definitely want to grab the 10W40 engine oil. This is especially important during hot summer days when the scorching heat of the sun can really amplify the heat generated by your engine.
Is 5w40 better for high mileage cars?
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.
Is 5w30 good for high mileage?
Both high mileage 5w30 and 10w30 engine oils have the same additives, the only difference is the viscosity at cold startups. Since both oils have the same operating temperature viscosity (30) and additives, they will perform exactly the same. However, 5w30 flows much better than 10w30 during cold starts.
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.
Does thicker oil run hotter?
Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.
Is 5w30 or 5w40 better for summer?
Both of these motor oils are 5 grade when cold, however, 5w30 oil is 30 grade, and 5w40 oil is 40 grade at operating temperatures. 5w40 has a higher viscosity than 5w30 with higher temperatures in summer, which adds to the proper running of the car.
What oil is thicker 5w30 or 5w40?
Viscosity The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30.
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.

Which is better 5w40 or 10w40?
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). … However, the main difference between these two engine types is that the 5W40 can work better than 10W40 in very cold places.
Which engine oil is best for summer?
As a general rule, you’ll get the best protection in the summer when you use a slightly thicker grade of oil, such as a 10W30 instead of a 5W30. Engines need a thicker oil in the summer months because of the summer heat and its effects on thinning the oil out.
Can I put 5w40 instead of 5w30?
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.
Is 5w30 good for summer?
5w30 is a great multigrade oil for use in low starting temperatures as well as high summer temperatures. It is also more fuel efficient since it creates less drag on the bearings and moving engine parts. 10w30 is thicker and may provide better sealing capability for older engines.
Can I use 5w40 instead of 0w20?
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.
