Which fuel, petrol or diesel.

[martin j.]

Daughter needs to upgrade her Leon mk2, 2l diesel but the miles are 160k and rising around 500 weekly, body, suspension etc are really tired. At a weekly mile usage of 5/600 should we be looking at petrol or diesel for the next late model mk3, is there a big enough difference in fuel consumption to cover the extra cost per litre of diesel still? She drives ‘enthusiastically’ so likes the diesel grunt over mum’s petrol model, maybe she should leave home 10 minutes earlier, mostly A road miles with a bit of dual, manufacturer consumption figures are no decent guide in the real world so needing the help of drivers, dealers recommend whatever they have in stock.

A mk3 Leon Cupra is a good shout. Plenty of ‘grunt’! Very good cars if she likes to drive enthusiastically. Not bad mpg either. Can find a lot of used ones for decent prices, with good specs too (sunroof, buckets, heated seats etc.)

 

[Seriously?]

The 1.4 TSi with ACT that Mrs S has in her Leon regularly averages 50mpg, although if your daughter is used to the torquey way a diesel delivers it's power than she might find it feels slow.

Got to be a diesel doing 500 to 600 miles a week, a cupra would be expensive to run as it should be run on super unleaded which isnt much cheaper than diesel.

What about a leon fr 184 diesel?

Diesel all the way if your doing that mileage. Also your daughters heavy foot will kill the petrol tsi mpg, you have tp drive like a potato to get over 35-40mpg

 

[DigitalSushi]

With that mileage it has to be diesel, unless your name starts with sheik..

Yeah my average was 36mpg in my 1.5tsi milkfloat edition. That was over 8k miles so good example. I probably drove it like your daughter does (lead foot)

Diesel 100% for 25k a year

Oi, who are you calling a potato?

Thanks guys, was just looking at the cost difference between fuels and mpg, best to asks users rather than trust my maths.

Mrs S current consumption (2018 1.4TSi ACT ST):

 

[G.P]

My 2010 Mk.2 2.0 Tdi PD140 averaged 46 MPG. MY 2019 Mk.31.5 averages 48/50 MPG, both DSG.

For me i do miss the low down torque but I so don't miss the extra weight around corners and the engine noise & vibration..

 

[Glosphil]

My 2012 Octavia vRS diesel (170) averaged 43.7mpg over 6 years. So far my 2018 Leon FR 1.4TSi (150) has averaged 45.3mpg. Both driven in the same manner.

 

[Mr Mustard]

When driving like your nan's in the car, our 2.0tsi dsg will return 50/55mpg on motorway journeys, helped by the high 7th gear.

Driving in a more normal (for me) manor will result in 45 on the motorway and mid 30s on rural journeys. 95 ron.

236 torques & 190bhp.

Looking at honest john - real mpg - averages of many drivers:
500 miles for 50 weeks of the year is 25,000 miles!
Using £/L £1.61 for petrol and £1.81 for diesel

TSI 150 vs TDI 150 using average MPG 45 vs 53
Would cost for the year:
£4051 for TSI
£3871 for TDI

Only around £180 difference! Less than I presumed before doing the math!
I think both would/could be low tax <£30 <2017 so no tax saving going TDI.

Obviously what you pay in your area for fuel & your actual mpg can change these numbers.

Using worst MPG 35 & 41
£5208 for TSI
£5013 for TDI
£195 difference

Using best MPG 56 & 64
£3262 for TSI
£3211 for TDI
ONLY £51 difference!

I'd have thought a FR TDI 184 would be perfect for this use case.

@martin j. - Aside from mpg considerations, if your daughter has to drive through - or works in - any large towns or cities, don’t overlook the potential for there being more clean air zones (CAZ) or ultra low emissions zones (ULEZ) introduced in future. Diesels need to meet Euro 6 emissions standards to enter these zones or pay a daily charge. I think diesels registered after September 2015 are generally Euro 6 emissions compliant, so that would mean some of the earlier mk3 Diesel Leon’s wouldn’t be.

 

[martin j.]

CAZ’s rare in rural Fife but if she transfers to Edinburgh it may be a concern, plan is a nearly new replacement car though, sub 12 months so should be within in regs, thanks for the thought, not something we’d considered.

Petrol also comes without the hassle of DPF issues too.

'high tech' small petrol's are not without their issues either like LSPI (Low Speed Pre Ignition) and carbon build up on the valves.

 

[BigJase88]

DPF @ 25k a year is not going to be an issue. Maybe at 2.5k a year but not 25k
