Sorry to do this, but here's another oil thread.
I'm just wondering what other LR3 owners are using for engine oil in their 4.4 V8s. Atlantic British sells Castrol EDGE™ Professional OE Synthetic 5W/30 Oil, but I can't find this locally. Castrol Edge Syntec 5W-30 has the required GF-3 rating and is available locally, so it seems like a safe choice. Mobil 1 synthetic is on sale, but it appears to be GF-5.
Thoughts?

GF-5 supercedes GF-3.

A 0W-30 makes more sense than a 5W-30 in Alberta.
Thanks for the link John, admittedly I tend to overthink this topic. A little bit of knowledge is dangerous.
I would personally use this http://lubes.mobil.ca/canada-english-lcw/carengineoils_products_mobil-1_afe-0w30.aspx# Going to a 0W30 will reduce cold start wear during extreme winter temperature without changing anything when hot.
They only specified GF-3 because that was the latest at the time they wrote the manual.
Conveniently the Mobil 1 is what's on sale at PartSource for $32 (5.4L).
I just used the Castrol regular mineral oil and changed it every 5K in our 06 LR3.
The owners manual has the oil/temp chart in the back that indicated 5w30 so I just used that year round. I do have a block heater for very cold days though. Synthetic is likely superior but after 320,000km and the engine hasn't skipped a beat. Just changed the plugs last month and they hardly even showed any wear!
