I have 2 Volvo Bus (5Liter & 8Liter Diesel) and Cargo Truck (7.5Liter Diesel),
If I connect HHO system, can i save fuel? i mean to reach MPG gain ?
Which type of HHO system i need ?
it not sound possible to me. does someone have experience with that?
I need to make changes in the electronics ? MAP/MAF/O2 sensor ?
the average is 7MPG for all those three Vehicle.
Thank you.
