5W-20 vs. 5w-30

I noticed the TSB #26-001-07 from 1/12/07 which recommends 5w-30 for ongoing maintenance for compass/caliber in international markets.
Is the US recommendation of 5w-20 just for CAFE sandard reasons? Does 5W-30 protect better in the long run?

p.s.: sorry I can't post a link to the service bulletin. I'm semi-computer-illiterate and haven't figured out how yet.

Congrats, you did it! The "30" helps for higher engine temperatures has always been my understanding. Global warming? But why only export

Maybe it has to do with availability.

A question to our friends with the export models (gas/petrol), what is the availability on 5W20 vs 5W30 where you live?

They are both readily available where I live (Brisbane, Australia), however I have the CRD - and dealer/log book recommends the 0w-40.

"SAE 5W-30 is required for warranty purposes in England"

http://www.machinerylubrication.com/...= Maintenance

They also say that if your engine overheats, the 5w20's would become dangerously thin, and over the lifetime of the engine, thicker oils may be better.

We use the Castrol SLX Longlife 0W-30 in our newer Volkswagens (Including the 2.0lt TDI) this allows for extended service intervals:-
