My civic did not have a manual when i purchased it. I always took the car to the shop to get the oil change because i did not have the tools to jack it up but now i do. They have either used 10w30 or 10w40. Which one is the recommended one? I also live in texas so the weather right now is reaching the triple digits. Should i use a higher viscosity then the recommended one so my oil wont thin out?

 

You'll get lots of opinions on oil. My suggestion is to Google it, research and form your own opinion.
