Sorry I meant to come back and edit my post........(don't post when half asleep & don't try to do maths hungover either )

60litres? I never run my car down past the last 1/4 on the gauge.

I get 450 km per tank in the city (well down to 1/4 on the gauge anyway), it usually takes 40-45 litres to fill from that point....doing my usual home -work - home weekday thing.
That gives me 8.8 - 10 l/100 yes?

I get 550km down to the same level on country runs which gives me roughly 7.6 L/100.....If I'm NOT booting it!

If I am booting it well....ummm..... 250km down to the last 1/4 mark = 16 L/100.

I've tuned my AFR's to be 15.4 -15.7 in cruise off boost, that has given me maybe another 30 km's per tank over the stock 14.0 - 14.7 AFR cruise.

Note: I've never run my car down to the fuel light.

P.s Why does it ALWAYS rain when I'm on holidays???

never realised you can do that with your AFR's 30km's is a big difference for something so small.
