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.
Is 10w30 better for high-mileage?
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 mix 5w30 and 10W30?
Yes, if topping up. If your oil must be topped up, then you are burning oil already, so the difference won’t cause more damage than is already there. 5W0 are essentially the same at operating temperature. It is only for cold weather starting that the performance will be different.
Is it OK to switch from 10W30 to 5w30?
You can use them interchangeably and would not likely even notice a difference at all unless it got really cold, then you’d find the 5w30 most likely cranking easier at cold start.
Is it OK to put 10W40 in a 10W30?
Mixing 10W30 with 10W40 Some say that mixing them is fine as long as you don’t live in freezing weather. Even if you put together synthetic and conventional blends of these motor oils, they show no harm to your vehicle.
What’s the thickest engine oil?
60 is the thickest oil in general use, but there are racing grades that go to 70. Most lubricating oils are now multigrade.
Is 10W-40 too thick?
Multi-grade oils could stay as close to the optimum viscosity over a range of temperatures – not too thick when it is cold and not too thin when it is hot. The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.
What does 10w40 oil mean?
In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the “W” number the better the oil’s cold temperature/cold start performance.
Which is better 10W40 or 20W50?
the huge problem is the other number though. The smaller number, (the 20 part of 20w-50) describes how the oil behaves at 40 deg C and a 20w at 40 deg C is about 10 times thicker than your engine wants. A 10w-40 is better at around 6 times thicker and a 0w-40 is much better at about 4 times thicker.
Which oil is thicker 5w30 or 10W40?
5w30 is less viscous while 10w40 is more viscous. The 5w30 has a viscosity of 30 at high temperature while a 10w40 has a 40 viscosity at high temperatures. When at high temperatures, the 5w30 oil becomes thinner than the 10w40 oil since 30 is lower as compared to 40.
Will 10w40 hurt a 5w20 engine?
The 10w-40 is to thick and will not flow as well as 5w-20 which will result in more wear at start up since the oil will take longer to circulate. Also even when the motor is at operating temperature it will still be thicker and not flow as well…
Can I mix 5w30 with 10w40?
As posted above, mixing 5w0 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.
Is 20W-50 thick oil?
The “20W” indicates how quickly the engine will start when cold or in cold weather. The “50” refers to the thickness of the oil when the motor has been running for a while. 20W50 motor oil is relatively viscous and thick. Most modern oils are 10W40 or even 5W40.

Which is better 15W50 or 20W50?
At colder temperatures, like in a resting engine, the flow rate is bound to be lesser. Interchangeably. Since the number on the cold start temperature is lower in your question, 15W50 motor oil would be faster to start up your ride, as compared to 20W50.
Can I use 20w50 instead of 10w30?
20w50 should only be used for old, tired oil burners. I use 10w30 in winter and straight 30w in summer. My oil pressure is comfortably high (as it should be; the engine only has 60k on it).
Can you use 20w50 instead of 5w30?
20w50 is actually thicker than 5w30. This will result in less fuel efficiency, less horsepower, and more engine damage because it will have to work harder to rotate.
