Any oil is better than no oil. It is not generally a good idea to mix
different brands of oil because there may be undesirable chemical reactions
from the different additives, but no immediate harm would be done. If you
run low on oil and can't get what's in it, then add whatever you can get.
Soon as possible afterwards, you should change the oil and filter though.
