How come i am not receiving updates for the forum 
Thanks Murtaza for such a detailed explanation...
I thought there's no activity going here...
Last week the consumption of my car dropped drammatically, a signal (one black box) from the fuel indicator was dropped just for about 60 Kms... Initially it was 100+ than became 90 than 60~70, so i went to toyota i9 yesterday for the tuning, the pic has improved, lets see the average... they charged me 800Rs...
which gives better economy "D" or "S"? i normally drive above 60Km/h and i donot try to calculate 0-100Km/h timings...
Last week I also changed the engine oil, I have put ZIC A+ in it, is that okay?
