Not many people I know put oil first. This is a little trick I learned many many years ago....and it has always worked for me....so I have just never changed it. I should also say, that different pots will cook differently. I have one pot that I have always used for rice....heavy walled pot. I tried cooking rice in another pot a few weeks back...and I used a different pot (something I have never done)....and it cooked totally different using exactly the same method.
I guess it requires a little experimenting....but it would be worth it. Rice is relatively inexpensive....and a little goes a long way.
*I started using the oil first method, when I discovered that I didn't care for the way garlic tasted in the rice....and yet I love garlic in my rice. It had a 'boiled garlic' taste. So the oil first method started, so I could saute up the garlic a bit before adding the rice and water.
