Is 10w 40 thicker than 5w 40?
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).
On the other hand, the 10W40 motor oils are thicker than the 5W40 oils for good reasons..
Can I replace 5w30 with 10w40?
Your vehicle does not use 5W-30 oil. 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.
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.
When should I use 10w 40 oil?
Overall the 10W30 will be the more appropriate oil for cold weather and non-performing engines while 10W40 is perfect for warmer temperatures and older vehicles.
Should I use 5w30 or 10w40?
10w40 refers to synthetic oils which have a viscosity of 10 when in low temperatures and a viscosity of 40 when in the high temperature of 100 degrees Celsius. 5w30 is less viscous while 10w40 is more viscous. … So at a lower temperature, the 5w30 oil will be the best to protect the engine.
Should you use thicker oil in an older 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.
What 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.
Will thicker oil damage my engine?
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.
Will thicker oil stop lifter noise?
If the oil is too thick then it will not pass through the tiny holes resulting in an increase in friction. The increased will not only lead to noisy lifters, but it may also increase the temperature a little bit. On the contrary, if the oil is too thin, it won’t provide proper lubrication as well as padding.
Is it OK to mix 5w40 with 10w40?
Mixing the two negatively impacts the properties of both. Just do an oil change asap and you’ll be fine.
Is 10w40 good for high mileage?
The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well. As long as you’re not hearing knocking or serious mechanical noises from the engine, the heavier oil should buy you many more miles of service from your vehicle.
What happens if you put wrong oil in car?
The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. … Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.
When should I use 20w50 oil?
Warmer Temperatures 20W50 motor oil is suitable for warmer climates, where the higher temperature causes the oil to thin. It is also useful for vehicles subject to hot temperatures and for those used for high-stress activities such as hauling or pulling trailers.
What oil is thicker than 10w40?
The difference between 10w30 and 10w40 is the thickness of the oil at operating/high temperatures, at which 10w40 is thicker than 10w30.
Can I switch from 10w40 to 5w30?
Yes you can change to total 5w-30 if engine is not reducing oil. It’s one of the best oils in market if you are getting it from total pump directly to avoid fakes.
Which oil is thicker 10w40 or 15w40?
Motor oil grade represents the weight of the oil when cold, as well as at operating temperatures. Viscosity or thickness of the oil increases with rise in temperature. A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures.
Is 20w50 good for high mileage?
Considerations. The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation. … Since its viscosity is so great, it can drag down the functioning of the crankshaft, resulting in less horsepower.
Will 10w40 hurt a 5w40 engine?
Yes. 10w40 is thicker than 5w40, it will not lubricate all the parts that need lubricating from cold.
