I have an 03 rx-1 er le and I had my oil changed last year and the dealer told me they used 0-40 brp synthetic. Do I need to get the same manufacurer? I'm new to these oils and would like to know are they all the same? i just need to take some with me next week in case it runs low in the tank.

Oils are generally compatible with each other and what oil you choose really doesn't make a lot of difference. Typically, the lighter the oil, the more power you get, so at 40, you're getting marginally less power than the specified 30. Certainly nothing that will hurt the engine, and probably not enough of a difference for you to even notice.
One thing to be aware of is that many automotive oils lack an essential additive for these engines called ZDDP in a high enough concentration. Again this is not likely to cause you any problems (I have yet to hear of anyone experiencing problems related to the oil quality and many use questionable oils). Some real good oils to use are synthetic amsoil products, either the 4-stroke sled oil (0w40), or even their 0w30 oils that are high in ZDDP for compatibility with old automotive engines.
Whatever oil you choose is really not that significant though. It is extremely important that you don't run out of oil, beyond that, I wouldn't worry too much, just grab whatever oil you prefer from your favorite automotive store and don't worry about mixing it with the oil thats in it now. Oils are generally designed to be mixable since in a typical engine, there is quite a lot of oil that doesn't drain out when you do an oil change anyways.
