Gilders is it an automatic, as i find with most auto’s I’ve had recently, that they programmed to keep the revs as low as possible for emissions and when you come to a hill or need to accelerate you got to put your footdown more than is needed if the revs was higher, which is maybe increasing fuel consumption.
My last car had sport mode and eco and it increased and decreased throttle responses, which for me i prefered to drive in sport mode as it meant i had to press the peddle less to make the car go and there was very little difference around town. On a longer journey cruising, i’d put in eco and get better mpg as the acc would not accelerate as fast back up to the set speed as when in sport mode.
My new car is a MHEV but it only has the one mode.
I sometime use the paddles, but it’s not always as it’s easy as just lettting the autobox do it’s thing. Guess that is maybe the downside to driving an auto. It cannot read the speed matching that is needed early enough and most of the time half way up a hill it then kicks down also.
Currently i did put some e5 fuel in my car and reset all the counters, as i’m just driving urban for the next few weeks to see what effect it has. Was getting 40 mpg but then yesterday did a bit driving in the hilly part of town and it’s gone down to 35 mpg all using just the auto.
When i next fill it then i gonna try using the paddles and keeping rev’s higher, see what effect it really has but i do suspect it will be better.
kind of is the same when i use acc and just leave it when it come’s to a hill the mpg goes down alot so i click the speed down if i can be bothered that is.
If your car don’t have paddles many do have manual mode like my 2017 golf did and one can use that to try and get a better mpg via control of the revs and gears.
