It was interesting when I was in Preston SEAT last week. I was speaking to a salesman and said I was doing 15k miles a year so might be better with diesel, and he said probably not. But I overheard a guy with another salesman, he said he was doing 12k miles a year and that salesman suggested that he should get a diesel! So everyone's opinion is different.

I guess you have to look at the figures properly as Diesel engines cost more and the fuel costs more too, and it's only offset by the mpg gain, of which if you're doing town driving, won't be that much.

I'm on the way to doing about 11k or so miles this year (based in what we have driven so far in 5 months) and Fuelly tells me the diesel is cheaper than my old TFSI by about 8p per mile. Aside from a lower tax band.
So, proven there that you don't need to do 15k miles for a diesel to be cheaper to run

Unless you are doing regular high mileage runs then the diesel won't be doing very good mpg, on short trips the petrol will be better, I've proven this with various dems over my regular trip to work. A vw up is more fuel efficient than a 1.6tdi Leon or golf blu motion by a good 9 mpg.

And diesels are slower than petrols people always think of the torque but you only have to drop to third and the petrol will say goodbye. I wouldn't touch a diesel having run a fleet of them and any new cars I add that cover less than 12k a year are now petrol, we have 4 polo 1.2s on the fleet at the minute.
 
I don't get it. How have we spent less on fuel since we got a diesel? Work in the same place, same working hours etc etc. Same route for 4 years now. Not even particularly long distances either. (20mi round daily)

Spreadsheets be damned. It's not dynamic enough.

Price per mile doesn't lie does it?

Not to mention over 100 a year less tax, so that's another few pence down per mile.
 
It depends how far you want to take it, do you want to factor in depreciation, servicing etc ... I've owned 3 diesels the best averaging 44mpg the worst 37mpg, the cupra is around 27mpg, ok factor in tax and diesels tend to be cheaper but the tax on a 1.8 tsi s around £175, what's the fr £150 ? I'd live to spend less on fuel and I could go and buy a 1.6 tdi which would bore me but I would have to spend £7000 and that would take a long time to recover. Diesels are only going to get more expensive too which is why manufacturers are pushing smaller turbo petrol lumps.

On the new Leon, given the choice between a 150fr tdi and the 140 tsi I'd go petrol, they are closer to the mpg figures than the tdi will be. I did have a passat on hire and did manage to get 69.9 mpg out of it butthatwas over300 miles. I have a new golf coming injustice under two weeks for a demo so I'll see what that gets
 
I suppose. I guess the only real reason to get a diesel is to lower your TCO. So it would include all.

But all said and done, the next one is most likely going to be a petrol :) It is just more fun, as good as the CR lumps are.
You pay for fun, so it's worth it.
I guess the 170s are a good compromise between fun/cost. But, as you said, as companies are going towards smaller lumps with turbos, the gap will close.
 
Yeah your money invested in fuel may be less, so at the pumps you feel better because you're going less/ spending less. However, you will have spent a fair few grand more buying a Diesel engine over a petrol engine! Normally around £3k more isn't it (at a guess)?

Ah, but they hold their value better as well :)
Hehe. And we got a cracking deal on ours anyway. The salesman knew nothing about the car so he went on Autotrader with us. He then said if he had known he would have upped the price :) hehe
Another benefit of buying from an exclusive car dealership
 
I've just costed up the £2000 difference between the 1.4 140 and the 2.0 150 against my current 2.0 143 Ibiza face-lift.

To cover the £2000 difference, based on brochure MPG and average price of petrol at 135.94p I'd have to do over 700 of my 260 mile round trips to warrant buying the 2.0 150 vs. my current Ibiza's 2 litre lump. 182,000 miles before I make back the £2000?!

Has seriously made me think.

I should mention this doesn't take into account that diesel is more expensive fuel to begin with. It's purely a calculation of how much extra money the 1.4 would cost me to fuel for a 260 mile trip based on brochure MPG and 135.94p per litre.

Precisely why the calculations need to be done :) I'd only prefer a diesel because I'd spend less at the pumps so I'd FEEL as though I was spending less, even though I probably won't overall due to the car costing more
 
The Ibiza is barely 5 months old and I've only ever driven diesels, but the Leon is calling!
Getting a 1.4 Leon would mean there's barely much difference in OTR/ROTR between it and my Ibiza (I have A LOT of optional extras!).

Okay maybe I'm cheating a bit by pitting my current 2.0 143 against the Leon 1.4 140 instead of the 2.0 150 which is even more efficient, but the car will have fallen to bits by the time it breaks even :lol:

Wonder how much the dealer will give for my Ibiza :rofl:

£2000 is only about 300 gallons so you must be doing about 600 mpg !!! Lol Suggest you get a new calculator!
Also, you will get some of the 2k back when you come to sell.

Edit: Or do you mean 700 existing trips? Also generally diesels last longer although the turbos have negated that a little.

While you've not had the Ibiza for long how about waiting for the 184bhp Leon?

Sorry should of said - my calculation is based on the extra cost of the 260 mile trip. I'd need to do over 700 260 mile trips for it to cost me £2000 more in the 1.4.

1.4 uses 0.5 litre more fuel per 100km
Trip is 418.43km
418.43km / 100km = 4.1843
4.1843 X 0.5 = 2.09215

So each 260 mile trip takes an additional 2 litres of fuel in the 1.4 vs. my CR 143.

I thought about it, but then I'd be looking at even more money.
That's one reason why I looked at the 1.4 specs and it came as a suprise how long its going to be before I see the extra cost of a diesel recouped.

I do have one concern though, would a 1.4 be laboured on the motorway cruising at 70/80?
Would sticking cruise control on at 80 be where I see the damage in MPG/wallet I wonder!
 
His figures are correct, it would take a long time to get the money back. Its the same thing with ecotechnology like VW having bluemotion. As a company i'd always add bluemotion tech as it lowers the Co2 and adds hardly anything to the lease rates, it terms of fuel consumption it makes hardly any difference.

A 1.4 wouldn't be labored on the motorway, what you might find is that it will be sitting at a higher rpm and motorway work is the diesels strong point. If 80% of your trips are urban then the petrol will be better, i don't know how long you intend to keep the car but DPF's are usually classed as a service item and need replacing every 5 years at a cost of £1000.

The 1.8TSI rolls in at 139g/km CO2 so VED is £120
The 1.4TSI rolls in at 119g/km C02 so VED is £30
The 150 2.0 TDI rolls in at 106g/km so VED is £20
The 184 2.0 TDI rolls in at 112g/km so VED is £30

Hope that is of help :)
