Your engine will not be damaged. The 20w40 oil is an oil that has a viscosity of 20 when cold but has a viscosity of 40 at operating temperature. The same goes for the 20w50.
Is 20W50 thicker than 10W40?
The 20W50 numbers refer to engine oil viscosity as determined by the Society of American Engineers. … The 50 refers to the thickness of the oil after the engine has been running for some time. 20W50 motor oil is relatively viscous and viscous. Most modern oils are 10W40 or even 5W40.
What is the difference between 10W40 and 20W 50 motorcycle oil?
So 10W40 means that the oil has the same viscosity when cold as SAE10 when cold. When hot, it has the same viscosity as hot SAE40. Likewise, cold 20W50 is as thick as cold SAE20 and hot 20W50 is as thick as hot SAE50.
Can I use 10W40 instead of 20W40?
In general, engine oils are classified by ambient temperature and viscosity index. 10w40 has an average viscosity of 10 in cold weather and a viscosity of 40 in hot weather. Also Viscosity 20 when cold and Viscosity 40 when hot. 10w40 can perform better as a replacement for 20w 40 oil.
Can I use 10w30 instead of 20w50?
The main reason for using 20w50 is to slow down the burning of the oil. If so, using 10w30 would speed up the burn. I’ve had oil burners before and have used 20w50 in the summer with no problems. However, with 20w50 your car will have trouble starting in very cold weather.
Is 10W40 or 20W50 thicker?
The smaller number (the 20th part of 20w50) describes how oil behaves at 40 deg C and a 20w at 40 deg C is about 10 times thicker than your engine needs. A 10w40 is about 6 times thicker and a 0w40 is much better at about 4 times thicker.
Can 20W50 be used instead of 10W 40?
Using a higher viscosity oil like you mention 20W50 instead of 10W40 can actually result in better fuel economy due to the greater resistance to flow. This greater flow resistance can also increase engine operating temperature.
Is 20W50 thicker than 15W40?
20w50 is probably too thick. Typically the second number is the viscosity of the oils. The higher the number, the thicker the oil, so 15w40 oil is a thinner oil in this case. Which is better depends on what the oil is used for. If it’s for a car engine, a 30 or 40 oil is better than a 50.
Can I use 10W40 instead of 20W40?
10w40 may perform better as a substitute for 20w 40. These are different types of engine oil.
Which is better 20W40 or 20W50?
20W40 is suitable for warmer climates and unlike 20W50, which is better suited for warmer conditions, does not cause sludge. …For example, in a colder climate, it only goes through two or three cold starts, but nothing beyond that.
Can I use 10W40 in my motorcycle?
If your motorcycle requires 10W40 engine oil, there is no need to switch to 5W40 oil. 10W40 works well with your motorcycle. Because 5W40 is a low-viscosity motor oil, it moves your motorcycle’s engine parts with ease. … This type of oil is quite good for lubricating engine parts during cranking
Can I use 10w30 instead of 20w40?
The 10w30 will float to 20w40 at high temperatures. It is therefore good in normal operating conditions, but there are small flaws during the winter session. You can replace it, but only try the recommended one. and do not forget to flush the engine before changing the quality of engine oil.
Is 10W40 good for a petrol engine?
A semi-synthetic, high-performance oil specially developed for petrol and diesel engines.
