Depends on system, Driver and Tune.

Generally a 4.0 on gas will be more efficient (price wise atm) than a 5.0

It all comes down the the fuel price.

I was getting Petrol at 50c a Litre last year, that's going to be cheaper than a gas vehicle.

Remember you use around 1/3 more in volume than petrol.. its the price that outweighs it..

how efficient would a xr6 be on petrol compared to a std 4 litre
