600km on a full tank is really kinda fake claim.
except you drive highway 100% with air conditioning off.
I don't know man. I think 600 km is about the average of what a fuel tank should be able to achieve. Of course, it should be with (majority) highway driving.
Someone I know in Indonesia, recently balik kampung, traveling on Avanza 1.3 for roughly 600km. Road conditions include jams at certain points, idling for a few hours waiting for ferry, and of course highway. One full tank all the way with some balance.
For me, I have 2012 Accord 2.4 (with over 250,000 km) and 2008 320i (120,000 km). Both can go at least 600 km per full tank. And this is in the middle east, where the summer temperature can reach 50C. Also, I keep a diligent record of each gas fill (full to full method) - so I know they can get me 600km at least.
But certainly, if TS is getting only 200+ km per full tank, something is wrong. Engine overhaul may be needed to see what the problem is.
