if you've been using 10w30 then just keep on using it...

Yup, just use 10w30. If you look in the owners manual, it says that 5w30 is useable in all temperatures, while 10w30 is fine in places where it is above freezing all the time (like San Diego). 10w30 is thicker when cold (hence the 10), which is added protection if it doesn't get too cold. The 30w refers to the weight at operating temp, so 5w30 and 10w30 are roughly equivalent (except that M1 5w30 is more likely to shear down closer to a 20w oil when hot).
