South, another oil thread but hopefully it'll be kept simple.
I decided that is time I really stay paying attention because oil is a lot more complicated than what I'm used to.
So the owners manual for my 07 3.2 AWD doesn't say enough for me to make a decision due to changes in oil testing.
Now, after doing some searching, the A1/B1 testing was replaced with a "C class" testing. But I've not found any information which says "This c-class rating replaces this a/b class rating". So I have no reference for oil.
I've seen a VERY wide range of response of both brand and viscosities. So let me detail my environment.
I'm in Southern Ontario, Canada. Spring is on the edge of finally poking is head up. Temps are hovering around freezing atm. I don't do any towing at all. Mostly daily driving to work (15-20min each way) and I like to go on long drives around my area.
I'm quite happy to use only synthetic oil but after all my reading, I'm just more confused than ever in what to buy.
Best I've come up with is Penzoil Synthetic but still no idea of what viscosity to get. The Volvo manual recommends Castrol brand.
I don't believe there is any significant oil consumption. (Just checked).
