Everyone seems very hung up on heating up the oil. But remember this, we are not living in the 1960ies anymore. Modern multigrade oil is going to lubricate fine at low temps.
What you really want to be sure is that the engine internals are up to temp so metal parts like pistons have expanded to their correct tollerances. The oil temp is probably not a very good indication of the temperature of the internal engine components if you heat it up artificially.
