What’s The Difference Between 5w30 and 5w20?

Basically, the difference is in the flow at high temperatures. Both 5w30 and 5w20 engine oils would flow at the same rate at cold temperatures.

But when the temperature increases rapidly, 5w30 would survive while 5w20 is likely to thin out.

Furthermore, when you switch to new oil, stick to that oil for a long time. Don’t use different oils at oil changes, else, you may actually trigger a fatal engine breakdown.

Motor oils are made with different additives meant to offer different benefits to the engine.
