I have about 85,000 miles on my pickup and I do a lot of towing. Was wondering which oil is best to use. I'm currently using Castrol syntec 5w30.
What type oil is good for a 02 Chevrolet Avalanche

Which engine?
For either: Amsoil ASL 5W-30
Other than the towing, what kind of driving? In Seattle, do you get stuck on the I-5 or do much town driving? How long OCI?

Its a 5.3L.
mostly traffic driving condition. I normaly change the oil around 5,000 miles.

Does the Amsoil ASL have low oil consuption rating?
Volatization is a term used to describe what happens to a fluid as it is heated to the point it begins to "boil off." Upon reaching a certain temperature, oil will begin to lose some of its lighter weight molecules as they "boil off" and leave heavier weight molecules behind. Not only does this cause higher oil consumption, this process can also cause increased viscosity making the oil more difficult to circulate through the lubrication system.
The ASTM D-5800 (Noack) is a widely accepted method of measuring volatility. Originally developed and used in Europe, the Noack test determines how much weight loss an oil experiences through volatization.
In the Noack test the oil is heated to 150°C for a specified period. The lighter oil fractions will "boil-off," leading eventually to oil consumption, oil thickening and a loss of performance. The test reports results in the percentage, by weight, lost due to "boil-off."
For example, before July 1, 2001, 5W-30 motor oil in the United States could lose up to 22 percent of its weight and still be regarded as "passable." Now, with GF-3, the maximum Noack volatility for API licensing is 15 percent. European standards limit high quality oils to a maximum of 13 percent loss. -from Wikipedia
And yes I know the info is dated. Anyone know maxium Noack volatility of GF-4?
For the ASL the Noack Volatility, % weight loss (g/100g) (ASTM D-5800) is 7.1
Is this what you mean by consumption rating? By the way, as far as the ASL's Noack Volatility rating, it doesn't get much better than this in 5w30 land.

Honestly, any 5w-30 or 10w-30 would be okay. With that being said, I would use a quality synthetic at 5000 oci and towing. Maxlife would probably be a good choice too. Most important, make sure you check and all should be fine.
I'm wondering why not ASL 10W-30 unless it gets down below 0*F in Seattle WA.

No such thing as "ASL 10W-30". Maybe you meant ATM 10W-30?
It does very occasionally get to 0°F here, but that is quite rare. 10W-30 synthetic would work fine, but I was asking for few particulars before straying from OEM/Amsoil recommendations.....heck I hadn't found out which engine.
But yes we could have a look at ATM, HDD, ACD.....
Amsoil ATM 10W-30
Amsoil HDD 5W-30 HDEO
Amsoil ACD 10W-30 (SAE 30) HDEO
ACD being a monograde loaded with AW additive will probably give the best wear protection, with HDD very close.
We could look at XW-40's as well, but for the 5.3L in Seattle I'd stick with XW-30.
Amsoil AMO 10W-40
Camu gave you an excellent answer. However, do you think the truck is burning the oil via rings or valve stems?
Hard to say if i'm buring oil or not haven't notice any blue smoke. I tend to loose a quart of oil around 1,000 miles and I have a 5.3L V-8
You're right, that's what I meant.
