^^^ besides the manual saying so, (although thats a good reason to use 5W20).... other oils can be used. If youre in LA, where it doesnt really get cold, 5W30 or even 10W30 is fine.

Im hoping all of you are using that oil once?
Your manuals say you should use 5w 20 if the oil is synthetic.

1. A turbo produces lots of heat, and the oil sokes the heat up
2. Oil breaks down when heat is exposed to it, sythetic oil last longer than organic oil when exposed to heat
Conitinue to use 5w-20,
1. 5w-20 is light and our engines are NOT designed to use a heavier oil (particually the piston rings) USing a heavier oil will not allow the oil to penatrate into all the ring section, this means your ring will not get the proper luberaction and you will have metal rings rubbing on metal cylinder walls, now this is not a fast process as only small fraction of the rings get exposed, but you WILL cause premature ware on the internals of you engine. Not to mention that if you go to thick, the pump won't pump the oil and then you won't have oil on the top end of you engine, hence a you will devlope a blown head gasket (I know all this from experience)
2. Using a heavier oil will also rob you of power. In the engine oil pan, the crank hit your oil and splashes it up on to the cylinder walls (no civic's don't have a dry sump oil injection system or any fancy stuff). This means the crank has to go through the oil, you can relate this to waving your hand in air and then putting it in water and doing the same thing, it will be harder to move your hand in the water, right? Now put your hand in the crisco do move it around, it's going to be really hard right? Well the thick the oil becomes, the hard the crank has to push to go through the oil, hence the less power that get to you tires and the worse MPG you get. I know that 5w-20 and 10w-30 don't seem to make a big difference, but remeber 1. that your crank is hitting this oil at 2,000-7,000 time a second and 2. that the properties of oil change the harder you hit it (it called historiesis).
So how come people didn't just use 5w-20 to start with back in the '50 and '60's? the same reason we don't use a 0w-10 now. If you use to light of an oil, it will seep past the ring and into the combution chamber. This really isn't to bad for you engine, but you catalytic converter and oxygen sensors won't like, not to mention you won't pass any type of emmisions check. The type of oil you use is directly related to the tolerances with in the the engine.
