Hi totchi1,

I am not Francis, but his friend, and I can answer your question.

First thank you for your kind words! The first kilotank was done by driving at a constant speed, around ~80 km/h, and was done on the same Gaspésie trip as the one were we did 1163 km later.

The biggest tank, the 1163 km one, was done by going at a constant speed, around ~80 km/h for the first part, and with alot of P&EOC (Pusle and Engine Off Coasting) for the second part.

If your Echo is in good shape (machanicaly), I'm sure Francis and me could do a kilotank with it, only with driving techniques. The aeromods help for sure, but driving techniques is 80% of it.

Did you try P&G? And at what speed do you travel on hwy? What your tire pressure?
430 km on a tank is weird... I do ~750 km on 1 tank with my Mazda 3 (with a 55L tank tho).
