Wow, prices are indeed dear in OZ!
Would there be any available 0W/5W-20 cheaper than that?
What's the cheapest syn 5W-30?
What's the cheapest 5W-30 dino?
If a 5W-30 syn is still cheaper than the cheapest 0W/5W-20 that's probably the most logical oil to run in your climate.
Id say that would be the cheapest and maybe even a trade price at that. There is no dino 5w20 at all. Without a doubt xw30 will be cheaper and more available than anything xw20. That's how it works here, thicker grades are cheaper.
"Fully dino" 5w30 is actually difficult to buy. The only one I know of is sold by Penrite for $37/5L and they market it towards Rotary engines which require strictly mineral oil. Synthetic blends are easier to get and cost between $40-55 a jug. The cheapest full synthetic 5w30 will be around $60 a jug from a shop (not including USA imports sold on ebay).
10w30 is not too hard to get and it's not too expensive now, It is usually at least "syn technology" or blend, lots on offer starting from mid $20s a jug
Contrast that to 15w40/20w50 dino, which is usually allowed in owners manuals, available for under $25 a jug anywhere.
