Re: O/T Petrol Consumption Tips

55 is best but a bit slow so 55 to 65 is efficient and a reasonable speed, anticipate and try not to use your brakes for as long as possible, don't accelerate quickly.

Why is 55 mph the most efficient speed?
It turns out that when it comes to wind resistance, at 30 mph wind resistance is four times as great compared to when a car is going 30 mph. When wind resistance hits 55 mph, the curve begins to rise almost vertically, so at 65 mph, wind resistance is greater than at 55 mph.

Although RAC say 45 to 55 way to slow for motorways

Driving at a constant speed helps, though it's not easy to do on our roads.

Sport mode I do about 18MPG

Eco about 30 MPG

Far too many drivers will accelerate hard then brake sharply, rather being more gentle on the gas and driving at a constant speed.

Ha I was thinking of the electric on salary sacrifice, however as I have family in Yorkshire I just prefer to drive on one tank rather than take 3 stops to recharge ( and that was a Tesla)

Have Mercedes diesel B class....on everyday journeys I get around 50-55mpg.....on long motorway trips (70mph) I get around 60-65mpg, especially if I set on cruise control.....electric? no way...

Currently have a Ranger pick up which does 34mpg at the absolute most, taken delivery of a hybrid suv today so be interesting to see how big the difference is.

Try coasting in neutral gear
I can get from the Caerphilly mountain snack bar to Morrisons supermarket in Caerphilly as long as the lights outside The Malcolm Uphill are green
That’s nearly two miles
On the way back I can get from the Travellers Rest to Cardiff Bay 😂😂

Re: O/T Petrol Consumption Tips

Get one of these, excellent mpg

Drove to West Brom and back last night from Surrey in a BMW 5 Series Diesel with 2 of my boys. Used cruise control as much as possible at 70 mph in EcoPro mode (whatever that is) and got 47mpg (it IS 10 years old….)

Steady driving, as mentioned elsewhere, helps plus saves on consumables like brakes and tyres.

Cruise control on motorways or bypasses helps a lot. I drive a Renault Captur and using cruise, driving to Brizzle and back via Eastern Ave M4 I'm getting just under 700 miles to a tank, that's about 56 miles/gallon. Without using cruise I was getting under 600.

Revving the shit out of the engine in a supermarket car park at 11pm does wonders for mpg.

We have a Tesla model 3 (basic model) and we get 200+ miles on a full charge of normal driving, 250+ with easy motorway driving.

I can get from Cardiff to Leeds without stopping once to charge, with change in the battery.
