Can I use 10W 30 instead of 5w30?

Both 5w30 and 10w30 engine oils have a similar SAE rating, meaning that they will perform the same at high or operating temperatures. The digits 30 indicates the viscosity of the oils when in high temperatures. 10w30, however, will thicken more when in a cold climate. 5w30 is much suitable during the cold season.

Can you use 10W instead of 5W oil?

There is a small benefit of using a 10W instead of a 5W oil in that the 10W will normally have less viscosity improvers in it. Viscosity improvers help the oil behave "thicker" at higher temperatures, but they do not actually provide lubrication.
