Welcome to the forum. :)
I would be suprised if your vehicle called for 10w30 and not 5w30 or even 5w20. Check your owners manual to be sure.
Good hunting and let us know.

Check the owner's manual to confirm the specified oil viscosity before switching from 10W to 5W. The vehicle may call for 5W-30 or 5W-20 rather than 10W-30.
