It's my first turbo car and everyone has told me that these turbocharged VW engines burn up oil. Especially when driven hard. So I checked the oil when it had a little over 500 miles and nothing. I then checked the oil today after passing 1500 miles and I was missing half a quart! Just want to inform you guys that this really happens TO ALL TURBO ENGINES. So make sure you check your oil every once in a while just to be safe. Wouldn't want many more people giving these cars a bad rep because of their neglect to maintenance.
In general, turbo engines can use up a bit more oil than normally aspirated engines, dut to the higher combustion chamber pressures that can result in greater "blow-by", that is when oil get's past the oil rings and into the combustion chamber, or when combustion chamber fuel/air get past the rings.
However, that's much more rare in modern engines.
What is common is that all new engines can use up more oil during the final "break in" while all the bits and mating properly, and from greater metal expansion/contraction while new.
This all calms down after a couple thousand miles or so. So, you may have greater oil use/loss during the first 1000-3000 miles, but it will go to nearly 0 loss after that.
My 2003 325i lost nearly a quart the first 3000 miles, and nothing after that and I have a normally aspirated engine.
But, you are correct in reminding everyone to check their oil especially during it's early miles.
