What is the best speed to get maximum fuel average in 1300cc manual city?

[ZainMahdi]

There is something interesting that I established over the weekend that may be of interest to the OP here. My LX470, with the aerodynamics of a shiny barndoor, gets 14.3 mpg at 70 mph, and gets 14.8 mpg at 80 mph. Engine efficiency near the torque peak matters too.

It can be due to a tailwind, varying terrain elevation, or even temperature differences between the 70 mph and 80 mph trip; a big truck like that suffers a greater penalty, compared to smaller cars, when faced with increased drag at a greater speed.

There is no way it can achieve greater mpg at 80 compared to 70 with reasonably similar environment variables. Unless of course it frequently slips its torque converter at 70 mph, and not at 80.

My observation is pretty robust Sir. I was just as surprised as you are. All the variables you mention I excluded. The point here is that as aerodynamic drag rises with the square of the speed, there may be a small area on the graph where gearing will make a higher speed more economical. That is the sweet spot, and it would vary for every vehicle.

90 kph according to my experience and I'm driving this car since 2009.

Engaging 5th gear at 60kph is a bad idea and puts load on engine.

Change gears at 3k rpms and accelerate moderately.
I'm getting 16 kmpl locally in Islamabad.

Meri liana lxi 2007 model milage 190000km. Total genion engine evwn coils are genion giving me 14km per liter at he speed of 120 on motor way. I calculate milage this way that when my fuel tank light on i rwfill fuel tank usualy 40 litwr or 41 liter petrol Dalta hay or gari full tank min 560 say 575 km karti hay or agar 100km tak speed rakho to 610 say 620 karti hay

Meri city 2010 model manual ki fuel average on motorway 21.2km hy. 2 persons with luggage.

On motorway you must be maintaining speed 90+. How is that possible to get this average?

But I heard that if you are running car on 40-50 at 5th Gear. I t can give you average over 23 also. try to reduce the RPM less than 2K. But what you are saying is totally different....

Motorway avg is usually between 16-18kph, but you can reduce your avg speed to below 100 (85-95) and keep your rpm nearly 2.5-2.7 it will go higher.

[sfjsag]

Keep your rpms stable between 2000-2500 on long routes and dont accelerate hard in city driving on a 1300cc engine.
By doing this i was able to achieve 12-13 in khi and 16 on long with AC in my 1300cc ride.

Dear actually he is right , change 5th gear at 90 speed
