I'm not a big fan of 5w30 in a turbocharged engine, BUT, if that oil is A/3 rated, I would think the additive package is robust enough to provide the needed protection for your engine.
For my Saab 9-3, I wanted an A/3 oil (Mobil 1 5w40), not an A1/B1 A5/B5 oil for long oil change intervals. I changed my oil every 5,000 miles (8,000 kms - I think). How many kms do you drive between oil changes?
I'd be very interested in knowing who produces that oil and I'd like to see a "data sheet" listing the performance characteristics. I also would not mind using that oil here in the States in my Infiniti and Toyota.
Is that an "Elf" or "Agip" product?
