First I've heard of an oil filter having this type of affect. I'd be interested to know why.

I think the ticking changed because the oil was changed from 0 40 to 5 30.

Too low (thin or light) = Metal-to-metal contact (friction and wear), poor
sealing and increased oil consumption.

Too high (thick or heavy) = Increased fluid friction,
reduced energy efficiency, higher operating temperatures and equipment starting difficulties particularly at cold temperatures.

Sound right?
