Likewise, people ask, can I use 20w40 instead of 20w50?
20W50 will hold on to the viscosity marginallybetter than 20W40 when the engine gets hot. However,20W50 mineral oil will cause more sludge than asimilar 20W40 because 20W50 will have more viscosityimprovers. Pulsar 150's manual recommends 20W40, but youcan use either, not much of a difference.
which is better 10w30 or 20w40? 20w40 is thicker at high temperatures (normaloperating condition of engine) compared to 10w30.For properlubrication at operating temperatures high viscosity is desirable.So 20w40 will be good compared to 10w30 at normaloperating conditions. And at low temperatures 20w40 isthicker as compared to 10w30.
Likewise, people ask, which is better 10w40 or 20w50?
The smaller number, (the 20 part of 20w-50) describeshow the oil behaves at 40 deg C and a 20w at 40 deg C is about 10times thicker than your engine wants. A 10w-40 is better ataround 6 times thicker and a 0w-40 is much better at about 4times thicker.
Which is better 15w40 or 20w40?
Only the weight of the oil, 20W40 is thicker thanthe 15W40, 20W40 is the best oil for the oldcars although 15W40 is very easier cold start
