Stop, Start journeys, Petrol or Diesel? - BobbyG
SWMBO has been on her last placement of nursing college, and this has been in the community.

I was horrified to see that the car's mpg had dropped to 29mpg, car is a 1.9dci Scenic 2004. Usual mpg is low 40s with normal driving.

However, in the community she is literally sometimes stopping off 3 times in the one street. Walking is not an option for various reasons.

If she had to end up getting a job in the community, and the Scenic is due for a replacement in July, am I looking at maybe getting a petrol if the economy is going to be that bad? Or will a petrol maybe be doing sub 20 mpg if not worse?

Taxis and Couriers do stop start journeys and they mostly use diesels so is it a case that petrol equivalent would deliver much worse mpg given these conditions than the diesel?

This might be the sort of use where a Toyota Prius comes into its own. I have had a good run in one, and liked it, but if you travel a lot on motorways the petrol engine is working full-time, and you'd be better off with a diesel. But stopping and starting would involve the electric motor saving energy and money.

A Prius costs much the same as a mid-range Scenic; maybe try one and see what you think. You have a better chance of finding a good Toyota dealer than a Renault one, though there are some good Renault dealers around. If you and she don't like the idea of a Prius, then I'd suggest diesel rather than petrol, depending on her overall mileage. Could she live with something smaller like a Yaris dlesel, or (by July) a new-shape Skoda Fabia TDI?

My Mondeo TDCi is poor (all are?) for stop-start and short journeys. Worse is in the cold. Mine being a Euro IV version (one of the first). It can do good MPG on a run but around town it is poor. But then so was the previous car, a VW Passat 1.8T (petrol of course).

I second the Prius. You could run purely on electric!

a small petrol, our bora diesel takes 5 mls to start to warm up, can't be good for the engine
and in cold damp weather the people inside are bl===y cold. jag.

Exactly the same with my 1.8 TDCi C-Max. Very poor MPG when my wife uses it for the school run, but good MPG when I use it to drive to work (35 miles, mixed A-road and motorway).

Re the Prius. How do you charge the batteries? You have to run the engine.

Donkeys years ago - when I was a boy the old maxim was

Never buy a doctor's car - all start stop.

In these days only a few in our street had a car - the doctor was one of the few.

The district nurse had a bike - how many MPG on a bike?

Diesel wouldn't be my choice, most CR diesels take an age to warm up & give abysmal MPG as they do it, probably doesn't do them a lot of good. A small petrol would be my choice. The capital cost of a Prius would be huge plus, its too big for a district nurse where she needs to park in small spaces.

My Scenic 1.6 petrol returned approx 29-31 MPG stop-start

I imagine that a Scenic or something of that type is required due to the restricted mobility of some of the passengers.

Second some of the above points. A petrol will warm up much quicker which is better for the engine and the climate in the cabin that in a diesel will stay damp for longer.
Stop, Start journeys, Petrol or Diesel? - DP
Yup, my Mondeo (pre-CR) is the same.

Around town / stop-start = 35 mpg
Commute (35 mile each way on motorway and A-roads) = 47 mpg

Our 1.4 (petrol) Fiesta can match its round town figure, although can't get close to its motorway figure. It also warms up in a couple of minutes

Agree also that diesels take forever to warm up, particularly if the engine isn't doing any work, such as crawling along at idle and slow speeds.

For local A to B running about, I would go for a small petrol.

How long is it left for? I know it's illegal but I'd be tempted to fit a turbo timer that will let you lock the door leaving it ticking over but that cuts the engine when the accelerator is pressed.

I work as a community nurse and drive a Peugeot 106 diesel (ignore my profile). Lots of stop start journeys as well as a rush hour commute to and from work in crawling traffic, and ccassional longer runs on A roads to get to outlying areas.

I average 55mpg. I suspect longer commutes at constant speed would significantly improve this, the PUG 106 is very freugal. Can't compare it to a petrol, but would think that fuel economy is going to be worse car for car.

Bear in mind that if SWBO goes in to community nursing on qualifying she will be re-imbursed for her mileage (42.p/mile or thereabouts), so the lower your running costs, mpg, tax, insurance, etc. the better. I would prefer a bigger car, but stick with the 106 as it is adequate for the job and my expenses cover my costs.

I'm sure you already know but insurance needs to be for business use.

I'd agree with Chuffer - old style diesel is the way to go. My suggestion would be a 205 STDT - PAS, and quite well appointed.

My 405 TD does 40 on short kids' taxi runs (2-5 miles) 44 on sensible XC motoring, and 42 if I bash it down the Autoroute at 80 mph.

Not only will you make money on the mileage, but you won't be suffering depreciation. Sensible bangernomics I'd call it, as there's no need for a new car in her job.

SWMBO has a 1.9D Punto that has been on this sort of service for 5 years, it averages between 49/52 MPG.
She started with the Seicento 900cc (Petrol) and the fuel consumption was so devastating (27mpg) that it had to be moved on very quickly.
Its worth noting that it was the multi stop start and never reaching operating temperature in winter that showed such a big difference.

Our other Vehicle, a 1.3 common rail Punto Multijet averages 57MPG on the same use.

Its a small lightweight diesel (IMHO) that is the best option.

Just to note, 5 years of ultra short, cold start trips, sometimes only a hundred yards, have made no impression at all on the 1.9D Punto and it still runs like new.

Thanks for feedback so far which has been very interesting. SWMBO is now a qualified unemployed nurse, it would appear that there are lots of nurses needed, but no one has funding to pay for them, but instead end up using "bank" or "agenecy" nurses which costs them more!

Anyway, back to motoring, some seem to think diesel would be better like for like than the petrol, others feel petrol better! Re the 106, last year we gave up an excellent Saxo diesel that had done us proud, to get something just a wee bit more comfortable, so don't think she would go back to that size of car unless it was more modern and luxurious (we now have a Fabia).

Will wait and see what , if any, job she ends up getting. But if she does get a community job (her preferred option), then I will be looking into every minute detail of petrol vs diesel!

Oh, and whoever referred to the term "District Nurse"? She didn't appreciate me calling her Nurse Gladys!!

Bobbyg, can't think of anything worse than 3-4 years training & no jobs, the situation is ludicrous and will undoubtely take us back to a shortage of nurses in 3-5 years time.

if you want to contact me via email (think moderators should be able to give you my address) I can possiible give some pointers on how swmbo can increase her chances of getting work

cheers

My 306TD does around 43mpg combined; 38-40 around town driven sensibly and about 47 on a motorway leg at a steady 70-75. Would still get about 450 miles to the tank even if it was driven solely around town- an equivalent petrol would probably only manage around 300. Usually get a bit better mpg in the summer months though.

Petrol or Diesel would not be any good stopping and starting like this 3 times in one street or doing any distance so short where the engine does not reach normal operating temperatures. No wonder the MPG is so low.

Best get a electric car for the short journeys as you describe. Or as already said " Get a Nurse's bike with a basket on the front"

Or a Honda IMA. Not that bad as town cars to be fair.

If the 106 is too small, then try a Citroen ZX TD - one for sale outside a neighbour at £695 on an R. Immaculate in/out, and an estate. If the budget is higher, Xsara.

A question to the more knowledgeable:

Would a Kenlowe Engine preheater be helpful in this situation?
Stop, Start journeys, Petrol or Diesel? - local yokel
It'll help with the first start. If she then spend 30 mins at each location the engine will lose most of the heat when parked, so it's not worth it. If each stop is only for a couple of mins (unlikely in the case of the OP, a nurse), then it might, but I'd expect the benefit to be pretty marginal.

The best solution would be an electric car.

My Yaris diesel averages 57mpg on stop/start/in town journeys. Around 67 on long runs.

Petrol engines on stop start? Choke usage= bore wear /high fuel consumption and exhaust wear.

SWMBO is THE expert on stop start motoring - average distance 1 mile. She averages 55mpg in a 106 diesel.
