I've been asking around about this. I have a 96 accord and on the oil cap and air filter it says my oil grade should be 5w30. I've been using 10w30. Everyone i know that has a honda uses 10w30 instead of the recommended 5w30. Even when i go to EZlube they put in 10w30. Is there a big difference? whats the diff between the grades anyway?

10w30 is thicker than 5w30 (in the sumer)

If you live where it gets really cold in the winters like sub-freezing and sub-zero consider switching to 5w-30 when the seasons change.

5w offers more protection when cold, 10w is better suited for hot weather.
