Question

Any good ideas for more miles per gallon with diesel?

Answer 1

Chuck any junk out of your car you dont need, keep to 56mph.

I wish i could stay in a straight line at that speed and i'd do it more...

Answer 2

remove any unnecessarily weight from your vehicle

only drive when you have to

avoid having roof bars

dont wind windows down...in this weather...lol

dont go over 70

dont hold in lower gears longer than you have to

dont put over half a tank of fuel in...a full tank is more weight to carry and you will get less mpg

avoid harsh excelleration

dont use the gadgets unless you really need to such as heater, air con, and so on

i'm sure there are lots of other things, i just cant think of them right now...sorry...hope this helps anyhow

Answer 3

Drive in reverse and your gauge will go up.

Answer 4

Let me put it this way - sometimes my 26yr old son borrows my 2 litre diesel car to go to work, he works just round the corner to where i work yet he gets about 12mpg LESS than i get on the same journey. The main difference is he seems to want to be first off the mark at any traffic light and holds the lower gears much longer than i do.

Hmmmm 50% diesel/50% water ....... strange that, water is not compressable and diesels run at very high compression ratio's.

Dont take any notice of these guys who tell you to augment your diesel fuel with cooking oil, heating oil etc.  Unless you have one of the old slow revving long stroke diesels you will just be asking for trouble. A modern elctronically controlled short stroke fairly high revving diesel requires good quality fuel if it is to last.

A gentler right foot could see you improving your consumption by 20%

Answer 5

keep your foot off the gas pedal . i'm crawling to work at a snails pace the way things are with fuel prices .

Answer 6

Most mechanical injection diesels will happily run on 50% vegetable oil straight off the supermarket shelf. Mine does!

Answer 7

don't go over 60mph

don't carry passengers or weight not needed

don't use wipers, heater, lights when not needed

freewheel down hills

don't accelerate so much

go up through the gears quicker

Answer 8

All the weight reduction and avoidance of harsh acceleration is fine.  However, a big thing is driving so that you anticipate better.  If you notice brake lights ahead and take your foot off the gas, the engine control unit stops sending fuel to the engine and so you use none while you slow down on overun.  (If you coast in neutral, you have to use fuel to keep the engine going, so don't do that).

Each time you have to brake you are wasting energy that you have used to speed up.  See if you can drive so that most of the time you don't need to brake, slow down and change down and anticipate, it makes a huge difference and you will be ready for those people ahead to do stupid things.

Anticipation does not necessarily mean snails pace!

Answer 9

add vegetable oil with your diesel, the diesel dilutes it enough so its not too thick and its marginally cheaper than diesel. You may have to look into it though, apparently if your using it as fuel you must pay fuel duty and if you dont you could be fined thousands of pounds.

Answer 10

Just use a lighter right foot. No need to blaze away from the lights - then keep to the speed limits and anticipate when you might have to brake - it helps to leave a slightly bigger gap between to car in front so you don't have to brake suddenly. Keep to smooth steady progress by changing up at slightly lower revs - keep your tyres up to pressure and don't carry unwanted stuff in the car / remove roof rack (I'm thinking of taking off the roof bars on my estate.

If you have an older / higher mileage car - changing / cleaning the injectors may help.

Answer 11

on the news yesterday there was talk about modifying your engine so that it could run on half water and half diesel!! the upgrade costs only like 200 bucks which will pay for itself in no time with today's gas. you should research that
