Hello,

I just wanted to ask why I always have to top up my engine oil every month, I get it serviced every year, I even specifically say get it to maximum but 1 month all oil is gone and the engine runs dry but there's no warning light on the dash. The dipstick shows no oil in the sump at all.
I have checked there are no leaks by the sump and the oil filter. What's going on? Thanks for your help!

it may either be burning oil through the valve seals or it has a head gasket problem. Also check your pcv system for blockage as that can also cause this.
