Check the level of oil in your car next time its cold. Low oil can show low pressure readings.
So basically, the answer to your question is 'No'. 10w-40 is not neccessary.

yes i know oil pressure drops as engine temps rise, due to the oil being less dense. the oil level when cold is right on the full line, directly above the cross hatched area.
