Had the same issue with my sportwagon, faint tapping sound quite annoying as the oil and filter are changed
every 6 months, (does not use any oil between changes, quite rare according to the forums).
I was using 10w/40 semi-synthetic for last 4 years, changed a few days ago to 5w/40 fully synthetic and
unbelievebly the faint tick has gone, the engine sounds more turbine like very smooth, the car still feels the
same on the move, it's always driven like a new car, now on 55,000 miles and 10 years old, mint bodywork
i can't bring myself to sell it, it's been so reliable, wish i'd used this oil grade earlier, suits the engine perfectly.
