Which is better 20W 40 or 10W40?
A 20 W 40 oil can replace a 10 W 40 if your winter / cold temperatures are not too low. A 10W 40 will afford better lubrication and performance over a wider temperature range than a 20W 40 oil.
Which is better 10W40 or 20W50?
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 better 10W30 or 20w40?
20w 40 is a thicker oil when compared to the original 10w 30 oil. So 10w 30 oil is going to flow better than 20w40 oil when you initially start it and also run it. If the oil flows better the better the oil will lubricate and protect engine parts.
What is 20W 40 oil used for?
It provides strong oil film for lubrication and total protection to engine viz. protection from rust, corrosion, with reduced wear under a wide temperature range in air-cooled new generation 4 stroke motorcycles.
Can I use 10W-40 instead of 20w50?
Using an oil of a higher viscosity as you mention, 20W-50 instead of 10W-40 can actually cause a higher rate of fuel consumption due to the fact that there is a greater resistance to flow. This greater resistance to flow can also increase engine operating temperature.
What’s the difference between 10W-30 and 10W-40 oil?
10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.
Can I use 20W 40 instead of 10w30?
20w40 is thicker at high temperatures (normal operating condition of engine) compared to 10w30. For proper lubrication at operating temperatures high viscosity is desirable. So 20w40 will be good compared to 10w30 at normal operating conditions.
