So I was cleaning out my garage a while ago, and ran across two quarts of old API SL Havoline 10w-30 oil. I think it's ok to use as top-off oil in my 2005 Dakota, but I just want to make sure, since it's probably 7+ years old and one API spec down from what my pickup specifies (SM).
Any issue using this as top-off oil that anyone sees?
