i just changed my oil on my h23 and i didnt realize i used 5w30 until i finished . i usually use 10w30 for my oil changes . i live in the south and the temperature is pretty hot out now, about 90.F . is it ok to use 5w30 ?

 

yes it will be fine

 

always use 5w30

 

Yup, no problem at all, you can go back to 10w30 if you so desire at your next oil change.

 

h23 - 5w-30 year round
h22 - 10w-30 year round
