My 2011 TC was serviced by an Indy place,
Oil level way over sight glass -
3 months later running down to Sids, its showing a quarter on the sight glass
By the time I'm home, the sight glass covered again
So i did my own oil change - 4L inc filter as described, and it;s over the top of the sight glass
As other have said, it can vary wildly
Best i ever saw was a young lad down the road, came to see me once, he'd topped up his oil on his first car..
but it was smoking good an proper ....
I pulled his dipstick, black oil to the halfway mark, then nice clear oil right up the dipstick
Turns Out - 5L fresh 10/40 into a already filled engine ... oh dear
We did an oil change the next day ...
