What's the most economical car?

pennylemon

I am thinking of changing my Ford Focus diesel soon. I drive about 45 miles a day, five days a week and I usually put around €50 diesel in a week. Tax is around €150 every three months.

My question is this; Should I switch to a small engine petrol? Or maybe a bigger engine diesel? The fella I work with has a Volkswagon Passat diesel and he reckons he was only putting €30 diesel a week... which really confuses me!

HELP!

Why are you taxing your car every 3 months? It will work out cheaper to tax it for a full year....

Plug

With your Mileage I'd go for a petrol. I wouldn't go for anything less than a 1.6 though.

Insightful stuff Plug... The OP may not know that tax is cheaper when you pay for the full 12 month period....

OK. You drive around 235 miles per week (assuming you drive about 10 miles over the weekend). Assuming 1.44 per litre of diesel, that's 35 litre's of fuel a week, which equates to about 6.7 miles per litre. That's OKish, I suppose, but you can get a lot better. My Dad's Fabia 1.4 gets 75mpg average, which is 16.5 miles per litre! That's close to 2.5 times better than what you're getting.

But you can probably squeeze more fuel efficiency from your car based on the way you drive.

si_guru

If you're going for petrol you need to consider a smaller engine to get some reasonable economy.

You don't mention a budget.

Also "the bloke at work" might not drive as far as you do.

If you're putting €50 of fuel in your car per week, that is more 45 miles a day in a Focus diesel. I get nearly double that distance from €50 in my FIAT 1200cc!

Thanks that puts in into perspective for me. My cousin drives a 1.2 Yaris petrol and puts the same amount in in petrol a week so my way would be better because I'm going a bit faster! lol

And the reason I pay every three months is because I haven't got €600 just lying around! Hence the inquiries into more economical car!

6.7miles per litre is approx. 30mpg
Either the OP has their figures wrong or that Focus is seriously knackered.

What size of car do you actually need OP?

pennylemon

Oh and I should probably mention that my budget is under €3000 too!

225 miles for €50 in a diesel focus? That's 30mpg in a car capable of over 60mpg. I don't think it's going to matter what you drive if that's the case. You're simply doing it wrong.

Ya, that must be the case. For some reason I looked on 6.7l/mile as about 45mpg - 30mpg is terrible.

Check your car or check your driving..

I get better mpg in an L200 ( 2.5L Turbo D and weighs almost 2 tons)

It's bananas. I remember a focus doing a run from Dublin to Wexford and back and getting 85mpg. Won some award, was in the news couple of years ago. Either OP is buying the worlds most expensive diesel or something is seriously wrong.

OP, I think you should properly test the fuel consumption of your Focus by "brimming" it. To do this, fill the car with diesel until it's completely full. Some people will say that to be 100% accurate you should fill it until you can actually see diesel at the top (brim) of the tank, but the point where the pump automatically switches off is fine. Then reset the trip odometer (mile counter) on the dash. Then drive as you normally would until the tank is nearly empty. Fill the car completely again and record the number of litres of diesel from the pump and the number of miles (or kilometers) you've travelled since the last fill from the dash. Report these figures back here.

I tried to find an online fuel consumption calculator but they all seem to be in US gallons. Anyone come across a decent one?

Why the need to fill it. In theory the fuel light comes on at the same time every time, so just as the light comes on, reset the clock, then stick €50 of fuel and see what milage is on the odometer the next time the light comes on.

pennylemon

Ok guys...

Im really confused now.. You're all telling me I'm doing something wrong. Roughly I put in €50 on my pay day and the light usually comes on on my last day, my mileage is spot on so I can't understand where I possibly could have gone wrong. Sometimes I might have to go soemwhere else but I generally just throw in tenner to get there etc.

Ill fill up the tank on my next pay day and we can properly work this out.

P.S. any cheaper cars out there?(while we're waiting) Looked up that Scoda Fabia 1.4. looks nice:)

vectra

Are you driving too hard?
You say you dont have 600 lying around to tax it for 12 months and then you mention that you have a budget of 3k to change car

Has it been serviced recently?
Does it need a service?
Is your air filter clear?

I say
Make sure it is running perfect,
Tax it for 12 months
Fill the tank
Keep the revs down and check your mileage
keep the revs down.

If you are getting hat bad return out of a 1.6 diesel that should be so much better then stay well clear of a smaller petrol car,
You will have to drive it too hard and it will drink petrol.
Purpose defeated.

How do you drive the car? Do you accelerate fast? Do you drive fast? Are you accelerating and breaking a lot, rather than being smooth?

Aggressive driving will use a lot more fuel..

If it's your driving style, then changing car will make little difference..

pennylemon

If I sell the car I have Ill get around 3k for it to buy a new one!

Also... Im serioulsy not sure if I drive the hell out of my car. I drive about 100kmp the whole journey, never break the speed limit but I suppose I would be very nippy in the towns etc. Is that driving the car hard? With revs? Someone should come with me and tell me lol Car broke down a few days ago so got a few bits sorted then.
I usually change cars every two years so the focus is ready to go.Sending it in for a service next week before I sell it. To be fair, I probably don't look after it very well really.

Is it possibly 45 miles each way you are doing a day?

It's 22miles each way from the house with a school run half a mile in other direction, each morning too.

Fair enough but the further you drive the more accurate the consumption figure you'll get and "brimming it" is the accepted norm for measuring fuel consumption.

I'd believe it. My Dad's Fabia got just over 86mpg from Galway to Limerick a few months ago! (He drives VERY efficiently).

Nissan doctor

It has to be something wrong with the car or your driving. Have you the boot full of stuff?, tyre pressures alway checked etc?

I just got a 1.7 diesel and drive a constant 100kmh for 80% of my commute and in my first week have got 900kms to €60 of diesel so if your only getting 235 miles(378kms) to €50 then somethings up!

Bigus

Ford focus diesel (should be ) one of the most economical cars you can get your hands on.

With my method though you can keep adding more money in during the week so that you eventually have €100 worth of petrol in the tank and then take the figure when the light comes on and it gives you the milage used in that €100.

Maybe the engine is running too cool or something, stat stuck open etc, is temp gauge showing normal?

Something would seem to be wrong with the car anyway.

mickdw

Focus should be very economical, something up with the car Id bet as you would really have to be abusing a small diesel car to get that kind of mpg unless you spend hours sitting in traffic or something.

pennylemon

It broke down on my on the M50 the other day, kept overheating. It was the radiator but then it looked like the water pump had gone and therefore the timing belt and waterpump would need to be changed. In the end, the mechanic took out the thermostat, replaced the radiator so I could get the car to my regular mechanic. He's gonna give it a good overhaul next week for me.

I think I might discuss all this fuel price stuff with him too now then!

Popoutman

Too many short journeys? Idling a lot while in traffic? Never getting to spend a significant amount of time in top gear near the speed limit? To see good fuel economy, you'd have to make sure that you are going on long relatively unbroken journeys at 50-60 mph without stops and starts on it.

As an example, a few years ago I used to have a Passat estate 90bhp diesel, and I was commuting from Limerick to Cork daily in it. €60-€65 of diesel was a full tank of about 59l or so, brimming it. I'd get about 750 miles before the low fuel light would come on, and I knew that I'd get from Limerick to Cork on what's left of the light came on on the motorway just outside Limerick. I was usually driving in reasonably light traffic that was at the speed limit, without much opportunity to overtake with the traffic coming the other way. So my journeys were maybe 10 minutes at a time in 5th gear with very gentle use of the accelerator and very little braking, and slowing down without needing to brake coming into the villages en route, and accelerating smartly back up to road speed once out of the villages. 600 miles a week of 50+mpg in a 1.6 ton car with a decently large engine, and another 100-200 miles a weekend doing other stuff.
If I drove that car every day to the shop and back, without letting it warm up and without leaving town traffic I would only get maybe 35 mpg or so.

Nah... Apart from the 3 minute school run, I have two Junctions and one roundabout in my commute, the rest is around 20-25 minutes of driving at 100kph.

If there is no thermostat in the cooling circuit, it will be running too cool when driving. That will have some impact on the mpg.

I haven't had a car for 5 years, but i was pleasantly surprised that i bought 20 euro of fuel today, and it only cost me 20 euro, like it did 5 year ago,
awesome!

Yea just seen that. It will be hard to do any mpg checks now anyway, until its cooling system is properly sorted.

But yea, you should easily get 50+ mpg out of the focus. I drive 350+ miles for 5 days a week and 45 euros usually does me most of which is motorway driving and some sitting in traffic

10 Top Tips for Fuel Efficient Driving
The way you drive and the condition of your car has an impact on the amount of fuel you use. Here are a few tips to help you save fuel and money.

1. Minimise your vehicle use
Vehicles are least fuel efficient and most polluting at the start of trips and on short trips. One reason for this is that catalytic converters (which reduce air pollution emissions) do not operate properly until they have warmed up. Trips of less than five kilometres generally do not allow the engine to reach its peak operating temperature.
Plan to do a number of errands in one trip rather than several trips and save both time and fuel. Try to avoid short vehicle trips by walking or cycling. This will save over a quarter of a kilogram of greenhouse gas emissions per kilometre of vehicle driving it replaces, as well as give you healthy exercise.

2. Drive in the right gear
Driving in a gear lower than you need wastes fuel, and letting the engine labour in top gear on hills and corners is also wasteful. In a manual vehicle, change up gears as soon as the car is comfortable with the higher gear but without accelerating harder than necessary.
Automatic transmissions will shift up more quickly and smoothly if you ease back slightly on the accelerator once the car gathers momentum. Avoid the use of power options which drop the car into a lower gear and therefore use more fuel.

3. Drive smoothly
Stop/start driving is much less efficient and more polluting than driving at a constant speed. Avoid travelling during peak-hours and on congested roads whenever possible.

Take it easy on the accelerator - more revs equals more petrol use. Drive at a good distance from the car in front so you can anticipate and travel with the flow of traffic. This avoids unnecessary acceleration and frequent repetitive braking that ends up wasting fuel. It's also far safer. If you see traffic stoppages ahead, first take your foot off the accelerator and let the engine's drop in power slow the vehicle, particularly by also changing to a lower gear. Don't continue to drive at the same speed and applying the brakes at the last minute. Getting back to cruising speed while the car is still moving uses far
less petrol than stopping and then starting again.

4. Minimise fuel wasted in idling
Most cars don't need to be "warmed up" by idling before setting off. This simply wastes fuel. Start your car when you are ready to go. Once on the road, minimise fuel wasted in idling by stopping the engine whenever your car is stopped or held up for an extended period of time. By having the engine switched off, even for a short period, you will save more fuel than is lost from the burst of fuel involved in restarting the engine. The net increased wear and tear from this practice is negligible.

5. Don't Speed
Fuel consumption increases significantly over about 90 km/h. At 110 km/h your car uses up to 25 per cent more fuel than it would cruising at 90 km/h. If your car is fitted with cruise control, using it during highway driving will help to maintain a steadier speed, which will save fuel.

6. Minimise aerodynamic drag
Additional parts on the exterior of a vehicle such as roof racks and spoilers, or having the window open, increases air resistance and fuel consumption, in some cases by over 20 per cent at higher speeds. Take off roof and bike racks when not in use. If you have to use roof racks, load them carefully to help minimise wind resistance or use a streamlined roof box.

7. Look after your vehicle's tyres
Inflate your vehicle's tyres to the highest pressure recommended by the manufacture and make sure your wheels are properly aligned. Looking after your tyres will not only reduce your fuel consumption it will also extend tyre life and improve handling.

8. Use airconditioning sparingly
Airconditioners can use about 10 per cent extra fuel when operating. However, at speeds of over 80 km/h, use of airconditioning is better for fuel consumption than an open window as this creates aerodynamic drag. If it is hotter inside your car than outside when you start a trip, drive with the windows down for a few minutes to help cool the car before starting the airconditioning.

9. Travel light
The more weight a vehicle carries, the more fuel it uses..Don't use your car as a mobile store room. Leave heavy items like tools and sports equipment at home when you don't need them on a trip.


10. Keep your vehicle in good condition
Keep your vehicle well tuned and regularly maintained. Get your car serviced at the intervals specified in the manufacturer's handbook.
Use the petrol that is recommended for your vehicle by the manufacturer. If you use regular unleaded in a car designed to run on premium unleaded you can expect slightly less performance and fractionally higher consumption. Using premium unleaded petrol in a car designed for regular unleaded may give better fuel consumption in some newer vehicles but it is unlikely to offset the extra cost of the fuel.

Your "method" was based on the fuel light coming on at the same time every time, so you reckoned that by lashing in fuel at this time and keeping track of the amount of fuel used (in €s I think you suggested rather than volumetric units) and the distance travelled you could ascertain accurately how much fuel was required.

By taking advantage of the reserve you are using more fuel again, thus the method is not accurate

The use of the reserve can't be tracked by your "method"

Do you understand my point now?

When the light comes on you have 8L* left, so you reset the odometer. If you use 2L of the reserve then put 50L then you'll use 48L before the light comes back on, and your odometer will show how many miles you went during the consumption of that 50L. It's really simple math but maybe it's a bit much to get your ickle head around. Think about it, maybe even sleep on it and you'll realise how stupid your last post looks.

*8L is a nominal figure as it's approximate as NissanDoctor pointed out.

I think thats the point, you can't get exact figures from approximations.

The 'brimming' method uses an exact amount of miles/kms covered and an exact amount of liters/gallons filled to give an exact fuel usage figure.

How exactly is one to know how much of the reserve was used?

The ickle head and my post looking stupid is comedy gold considering you are expecting folks to somehow know how much of the reserve they have used.

Please do explain how the quantity of fuel used from the reserve is to be derived..... also your method was based on the € amount, you've transferred to litres now have you?

It doesn't matter what the figure is. The light comes on at the same time every time thus giving you a marker level in your tank.

I used whole numbers to make it easy for you and you still don't understand. It doesn't matter how much you go into the reserve the fuel used between reserve lights is still the amount you put in the tank at refilling whether you go 2 or 5 litres into the reserve. Please say you understand that bits pretty basic.

RoverJames wrote: »

I used approximate again because as NissanDoctor pointed out all tanks are different but you still don't get my point. You think driving with the light is some kind of lottery to see if you make it to a fuel station.

Apart from maybe drawing a diagram I can't explain it much better. Both methods use the same principals I just the light as a marker in the tank whereas the other method uses the brim as a marker.

Your method is not accurate, the light coming one will vary from time to time, the brim won't unless the service station is built on a slope. The light will not come on at the same time every time.

Anyone who reckons 8l is approximately a gallon and a half has a very very generous idea of what approximately is.

I fully understand why you reckon your method is sufficient if you reckon 8l is approx a gallon and a half.

FFS RoverJames. I said 8L as that's the level of the VAG reserves. Other car manufacturers vary. Some might be as low as 6L. So to approximate between these two very different figures I used 'a gallon and a half' as it's approximate and easily fitted into my point about how far one can travel in the reserve. If that last reply is the moronic standard of your next reply can you do us both a favour and don't post.

You wrote/concocted that summary post as I was writing mine so I was actually referring to the one above it.

In terms of the summary they were all because you couldn't (and possibly still can't) understand how the light can be used to calculate mpg.
