Increasing mileage efficiency. How do you do this?

Philipp_Bach

For all car drivers and lovers, I believe, it will be interested to know about fuel and oil additives, that comes today to us through the market.
Is this a real case to improve mileage efficiency?

What kind of benefits they bring to you and your car?

What is the efficiency of using them?

How do you measure the efficiency?

They don't work.
Save your money and buy more fuel with it.

The only effective way is by learning to drive efficiently.

Drive slower, empty the boot, keep on top of maintainance. Most importantly don't buy anything to aid efficiency.

Treat the brake pedal like a fuel drain. Every time you press it, you waste fuel that you spent accelerating to the speed you are now losing through the middle pedal.

Drive with anticipation and save fuel. For free.

Drive less save more fuel.
Save money not buying additives.  I think Esso had to stop advertisinig their fuel saving fuel because most
drivers did not find any saving.

Measure efficiency, rip the engine out and attach to a dyno where you can regulate the temperature and hooked
up to many computers to monitor every parameter. Then keep adjusting until you find the magic number.

The issue is the magic number may not work for every seemingly identical engine.

Loads of fuel can be saved mainly in the city. Predict what will happen soon, learn patterns. Do not accelerate if you know if you will have to brake harder soon. The less you braking, the more fuel you save.

I have always been intrigued by the Haynes manual. It gives you all the tips on fuel efficiency and then says: "Driving techniques associated with good fuel economy tend to involve moderate acceleration and low top speeds. Be considerate to the needs of other road users who may need to make brisker progress; even if you do not agree with them this is not an excuse to be obstructive." What does it mean? We have told you how to be fuel efficient but please don't do it? Please don't obey speed limits? If there is someone close behind speed up?

Seems absolutely self-explanatory to me.

If anything, it's a blatant truism restating chunks of the Highway Code, especially 144, 146, 147,  Y'know, the blatantly obvious bits they only have to write down because of the hard-of-thinking... The stuff you'd have failed your driving test for not doing.

Anticipation, forward planning, both of which involve looking beyond the vehicle directly in front.

Both of those minimise braking - brakes = heat = energy which has to be replaced by the further addition of fuel.

Light right foot and ignore the traffic lights Grand Prix start.

Oh, and don't let anyone other than yourself anywhere near the vehicle for maintenance!

"How do you measure the efficiency?" As a rough guide -

Efficiency = (useful energy transferred / energy supplied) x 100.

Keep left and don't be a dobber, drive at the speed limit if it is sensible and safe to do so.  It is really quite simple.
