I live in a comparitively warm climate, but even in cold weather never warm any car by letting it idle. If you have to do that to keep from freezing, that's ok, but don't do it thinking you'll make the engine last longer. Engines, and their oil, get to operating temperature fastest by doing work, so as soon as the oil pressure is up, I'm in gear. This was a recommendation of the SAE (Society of Automotive Engineers) that I've followed on every car I've owned. For Waspie's 2.8 I'd use the 5W-30 year-round and not worry about it. I also use (in the V-6) common Valvoline MaxLife, Castrol GTX, Mobil Clean 5000, etc. and have no issues with lifter noise or oil consumption.
This isn't a diesel. Diesels are the ones that need to be driven to warm up.

Do what you like and are comfortable with. I had a neighbor who would start his car and then go back inside to have breakfast, thinking that his engine would last forever (maybe it did but he's dead). Warming up an engine by idling is a legacy of the days of carburetors and manual chokes, long gone now that we have ECUs watching air temp, coolant temp, O2, MAF, etc.

I have a 2.8 and I use one of the Hi Mileage dino oils. Since it really doesn't cold where I live, I stick with a 10W40.
Synethic in a 2.8 is only worthwhile if you extend the change intervals.
The best way to warm up an engine is by driving it. And I use to live in a cold climate. Idling is old school.

I really don't like getting in a cold car. 5 minutes running in the driveway preheating with the seat heaters turned on.
I know its common in turbo cars for the ECU to limit boost until the engine has fully warmed. This lends logic to both arguments as to how you should warm your car up. As I'm sure that one has been beaten to death I'll just stop there.
Who even makes a synthetic blend any more? I know castrol used to make one that I used in a civic I had a few years ago but I don't remember seeing it recently.
I much prefer longer change intervals. We're long past 3000 mile OCIs.

The oils you mentioned are more than adequate for your needs. Theyre all 502 505 spec so once a year wouldnt be an issue either. I wouldnt push it more than 5-7500 mi though.
