This is a SPA forum, so whatever you're using in your 3.2 is DEF not what is spec'd. The spec is below, and it's not even officially available in US from Castrol.What is specced for your engine? That Castrol is A1-B1, which is what my 09 XC90 3.2 is supposed to have. That spec has been obsoleted to A3-B3. I think the viscosity may be a little better if it crept up to 30w. I bought Mobil 1 A3-B3 0-30w from Costco. Be careful with A5-B5, though, it may not be good for earlier engines.

For Castrol you need to find Castrol Edge Professional V 0w20 and make sure it has VCC-RBS0-2AE on the label.
I've read that a few times and went w/ the FCP euro liquidmoly oil change kit just like everyone else.Check the below Technical Journal

Duh. Of course. Thanks for the clarification.we dont have trouble with quarts, we get 55gal drums of 0w20 castrol pro v. supply line is a little different when you go through hundreds of gallons a month compared to a couple gallons per year.
