I have tried many other bikes myself and measured fuel milage and talked to many other riders on different bikes and I have spend quite some time and energy researching this issue. Even a BMW GS 1200 with a pillion got better fuel milage than I have, then clearly something must be wrong. I had a Suzuki Dr650 on New Zealand and even the carburated old school Dr got waaay better fuel milage than me.
20 kms/l will be 5 l 100 kms which is what I get nowadays riding max 80-90 km/h.
I have never paid any attention to the oil drain pipe. The last posting in the longest thread you linked to was from 2010 so maybe Yamaha has changed this?
I have never had any oil in my airfilterbox, then I never ride it at speeds above 100 kms/h for a long time. So I dont know....

Hello
3.5l/100km on a XT660Z?
Not in my wildest dreams. Never read that someone achieved this over a long term back home.
I did 4.75l/km riding really relaxed on small dirt roads.
Up to 5.5l/100km on highways but hardly over 100km/h due to saving tires.
Wind and lugguage play a big part in fuel consumption.
So to me, 5l/100km on average is nothing to worry about with the engine.
I bought an other used Z (better than restore the old one) and it uses the same amount of fuel.
Yamaha changed the part on the new models and on the service if complained by 08-09 models.
I bought my Z new in 2011 BUT Yamaha Switzerland had too many 08 models on stock, so they slipped me a 08 in black.
Because of the rectifier problem I didn't go for a used 08-09 model and bought a new one... Found out on the road, best indicator ist the seat, 08 model is made of only one piece , then of course the VIN and Google.

3,5 l/100 kms is what I had on the Ten when it was newish. And 4l/100kms after changing sprockets to 3 teeth more on the rear and loaded up for a RTW trip.
And now 5l/100 if constantly ridden in fuel saving modus.
Its obvious that something isnt right, and thats with your bike too. A carburated Dr650 has 25 % less fuel consumption, a new V-Strom has 25-40 % less fuel consumption, a BWW 650 GS with rotax engine the same as the V-Strom. I could go on until we both fall asleep of boredom. 5l/100 kms on a fuel injected bike ridden moderately is faaar too much. My dads 1400 kilo 125 HP car uses less fuel than my Tenere....  
My Ten is a 2011 for sure. So then I can stop thinking about the oil drenage problem I hope....

Hello
The above written 4.75-5.5 l/100km is what I remember by simple calculating in the head at the gas Station.
Just had a look at my statistic of my RTW.
I wrote everything in a excell, but only xx.x Liter, so there is a statistic error, in reality it's higher than that:
104150km 4.55l/100km
Big brother has more data:

no you didn't, 4.XX is what you can get most of that engine unless you're riding on neutral downhill...
3.xx gets my nc750x parallel twin and not always...
Yamaha XT660Z Tenere MPG - Actual MPG from 65 Yamaha XT660Z Tenere owners
BTW is it your first bike?
p.s.
Dude, and you really think that RTW trip tests the bike reliability the most and makes you more important ??? Number of steady, empty kilometers accumulated ??? I can as well put bike on stand in my garage and make it run all night.

I have told you what fuel milage I got and if you dont belive it its your problem not mine.
I have had 9 bikes alltogether. And I have rented many different models to try them/test them. I have been on organised bike tours with different models and I have borrowed friends bikes - so I have experience on around 20 different models.
Yes of course a RTW trip or a long overland trip is the ultimate test for a bikes quality. Because that let the bike be tested with under all kinds of climates, all kinds of road conditions etc etc often loaded up with gear and equipement. Actualky that goes without saying. This forum is actually intended for overlanding and RTW-trippers. Im sure there are a forum that suit weekend riders like you somewhere out there...
