Volvo 2.5 L petrol engine (BJ 1993) & automatic – full gas or slow gas? There was the thing about the bad fuel consumption in the “part load range”. What was that again? Is it better to accelerate with almost full gas, or quite slowly ? Simplified thought, is the energy that has to be applied to get to 60 km/h in urban traffic the same, right? Have you heard that 3/4 gas is optimal, but can someone contribute something well-founded to it? I might be driving quite wrong, is there rather the always slow accelerating type … to love the consumption ) Thank you !
