Thanks.
I have a RAV4 hybrid and kept track of my fuel economy using the full tank method.

Starting ODO i tracked: 970 km

Liters - ODO - KM/L ------ Reading from dashboard km/l
39.89 - 1728 - 19.00 ------ 19.1
19.35 - 2088 - 18.60 ------ 19.1
50.46 - 3032 - 18.71 ------ 19.4 *** Almost 1000km on a tank in metro manila
25.674 - 3555 - 20.37 ----- 20.4

I'd say that the dashboard reading is pretty accurate to about ~3-5%.

Unfortunately I cannot find if the car stores my average speed per full tanks.

My route is las pinas to makati (using skyway) or BGC (slex - C5). I would actually lose a little fuel efficiency going a steady 100km/h then gain it back once I hit slower moving traffic. I admittedly will avoid the brunt of traffic by leaving earlier than usual, but I don't baby it when driving.

Regarding the oil, I am also disappointed that CASA does not use 0w16 (I talked with the SA, they do have 0w-xx but use it only for supra / GR Yaris), but 5w30 is recommended in the manual anyway and I am getting fuel economy that more than matches the US EPA (albeit their model is a 4x4), I am happy with it. Also I am thinking that the added cost of the 0w-xx oil probably nullifies fuel further economy savings. I am no oil expert but i think that the next step will be 5w-20 oil when DIY'ing will be the closest to 0w-16 since the 'w' is oil viscosity at really low ambient temps. 5w-20 is also recommended in the manual anyway.
