The smaller number before the "W" indicates the grade is suitable for use in cold temperatures. The lower the number, the lower the temperature at which the oil can be used for safe and effective protection. A 0W or 5W would retain its fluidity to a lower temperature than a 10W, for instance. Think of the "W" as standing for "Winter". Altering the temperature at which the oil retains its fluidity, or controlling the "pour point" is accomplished with additives.
The "W" number is NOT a measure of the oils viscosity, although a lot of folks tend to think that a 5W oil is "thinner" than a 10W oil.
The larger number is the viscosity, and indicates the viscosity of the oil at operating temperatures ... so a 5W-30 is the same viscosity as a 10W-30, but the 5W will be suitable for colder temperatures.
The higher the larger number, the better the protection in higher temperatures.
For instance .... if I owned a motorcycle ( ... and I will again), I might run a 10W40 throughout the season in Canada. If I was touring through the southern USA in the summer time, figuring I would see 100 degrees F, I might want to go for 20W50 for the trip. If I usually ran 10W-30 in my car, and was travelling to Yellowknife in the winter, I'd be shooting for the 0W-30 (not to mention a block heater, and maybe a note from my psychiatrist!)
I hope this helps.

You'll see what choices Amsoil recommends for your beast. You will notice that 0W30 is recommended, as well as the 5W20. I have verified with our technical services that Amsoils Series 2000 0W30 does indeed meet or exceed the specs of your engine. I am using the 0W30 in my 2005 Civic, and it runs like a top.
