Hi, Paul, thanks for the advice. It's a new car (only done 750 miles), so no worries just yet. I think mine's an annual or 12,500 miles though interestingly, the service indicator says 15,250 miles to the first service. I think Peugeot had the same 1.6 engine, which I gathered from their forums was prone to early turbo failure. My previous car was 407Sw with the 2.0 diesel, which I changed the oil in every 6 months, and I'll probably do the same with the C5. Looking forward to being a member. Regards, Richard
