Accidentally dumped 5w-30 in the ZJ...Change?

Well, I was just pouring in the new oil and realized I got 5w-30 instead of 10w-30. Can I leave it in there?

I don't think it would cause any harm in keeping it in there. Do a compromise & keep it in there another month & change it before the weather gets real warm.
Most of the newer cars call for 5W.
This is from the 98 manual:

The 5W and 10W refer to the low temp (or "winter") viscosity. The difference is so small that your engine won't be able to tell the difference during late spring and summer. Both the oils you mentioned behave like 30W viscosity oils when the engine is warm and there is no difference then. Bottom line, don't worry about it.

ITS FINE!!!! There is barely any difference at all between 10w30 and 5w30, only their cold viscosities. I am running 5W30 in my ZJ right now.
