A way to use less petrol?

RED DEISEL IS ILLEGAL ON THE ROAD - so if you use it you would be fined heavily. I can assure you that evenif you have emptied your tank and refilled a few times after it can still be detected.

a few problems- -

firstly the petrol you save - some will be spent going to re-fuel on a mroe regualr basis.
secondly, other features of your car add far more weight - example spare tyre - replacing this for a space saver light tyre has the advangtage of weight - however they do need to be replaced within a 40km distance.

the best petrol saving tips i find are...

* keep your engine tuned correctly (you can do this yourself cheaply from maplin if your willing to have a go)
* hit 5th/6th gear by 37mph
* cruise if you do not have modern car or a modern car form a less developed manufacture (for example kia) - modren engine systems (for eample renault) cut of petrol usiage when the accelerator isnt applied and the car is in motion in gear.
however, it will use petrol if the car is ;left cruising out of gear to keep it turning over. other manufacturers such as kia are not up to date on such technology on a large proportion of their engines.
* consider an lpg convert
* consider a diesel
* but an old diesel (preferbly non turbo or early turbo, do a few internet searches and finfd out how to make your used cooking oil into petrol - its alpot easier than you think. by law you should report and pay all duty on the fuel you use. i know of firneds who have used and continue to use this very successfully.
the only main odwnside - is a very slight loss in power (its a non turbo diesel - as if you care anyway, not reccomend when its going to be very cold (although adding a drop of petrol and diesl seems to do the trick). even paying the duty - you can still work out as 25p a litre, and msell like a chip shop - ther are ways to reduce the smell.
i could go on alot more about this - way to much detail to go into.
* become friends with a farmer and buy some nice cheap red diesel.
* dont do a car journey for less than 10 mins or 5 miles. you will wreck the engine over time and destroy your fuel economy.
* motorway speeds of 55-60 are ideal for maximising mpg.
* stick to petrol engines no bigger than 1.3/1.4


hope its of help.

Advice re getting into high gears quickly was fine in the days of carburetas. With engine managenet systems there is a big penalty for being in too high a gear. TRhink about it: most cars are at their most fuel efficient at around 55mph. Check your rev counter and you will find it reads around 2000rpm for deisels and 2500 for petrol engines. Anything below that rpm the engine is pushing excess fuel into your catalytic converter or out into the atmosphere! We should aim to drive keeping as close to optimum revs as possible. In practice that usually means 3rd gear at 30mph, fourth at forty etc. Give it a go. It really works.

Not using your car is sadly becoming the only way to save money/fuel:shhh:
