Diesel on both accounts

even allowing for Diesel to be cheaper petrol works out better .

if your driving under 20,000 km a year, there is absolutely no reason to have a diesel.

visual

The service intervals are the same
cost of oil is same
cost of oil filter is the same
cost of air filter is the same

fuel filters is about same but these don't get changed often

Lest often
Diesel
DPF fluid or replacement

petrol
spark plugs and coil pack or leads

rest is down to repairs

Stheno

Tbh it depends on the make of car, driving an alfa tspark means belt changes on a petrol at every 36k miles, spark plugs every 60k

Don't think there is a definitive answer

glow plugs on a diesel, getting the EGR cleared/ blanked / whatnot

there are some expenses on both sides , but under 20,000km a petrol is cheaper per kilometer to own.

Daysul are far more expensive to own, if you do upwards of 20k miles a year they can be good work horses but they definitely need far more tlc.

A decent petrol is in a different league to any diesel, I have seen quite modern big engined diesels all the time here and they sound like New Holland's compared to my car.

OP has another thread here where he mentions that his mileage will mostly be city driving so petrol or hybrid is the way to go imo:

The main argument for the petrol being cheaper to run is that the petrol engine is simpler. The lack of complexity means less potential for big repair bills. This is fast becoming an outdated concept IMO.

The new super efficient (read super complex) petrol engines don't have this advantage over their diesel equivalents. Most of them have turbochargers and high pressure direct injection fuel systems just like a diesel. They have dual mass flywheels just like a diesel. They also have expensive emissions control systems just like a diesel. Diesels have a DPF, lambda and exhaust gas temp sensors. Petrols have multiple lambdas, catalytic converters and NOX sensors. The price of these items for most modern petrols is eye-watering.

The ony real advantage for petrol over diesel is for people who do the vast majority of their driving in the city, for these people buying a diesel is not a good idea due to the DPF.

Yeah , if you could claim it on petrol id be driving a ford f150 V8 right now, sadly the revenue say no

Have to agree with this, people going on and on about DMF and turbo failures in modern diesels as a means to critisize them since they're seen to be less of a drivers car.

What was it last year, 70%+ of new cars were diesel? At that rate, I'd expect 70% of problems to be with diesels, for things that tend to go wrong with diesels, hence fueling the rhetoric.

Had to get a Clutch and DMF for my car recently, which I didn't even think it had. Got a great discount on a Luk kit, and had it fitted by an uncle of mine who's a mechanic for more than a fair price, but the retail price was eye watering at you said, and labour would have been the same.

I agree with George. We need to wait a couple of years to see how these new direct injection turbo petrol engines perform over time. From what I know there is an issue with dealing with combustion deposits that are inherent to direct injection. One way of trying to deal with it would be frequent oil changes but that obviously increases the cost of ownership.

where does the 20,000+ KM diesel>petrol justification come from ??? is this based on buying new or like option for a 10yr old second had petrol V diesel running costs

If we got like the U.S where an oil change is no big deal,is done in an hour and is cheap,alot of direct injection issues would disappear. Frequent oil changes are key.

An Hour?, way too long.

Most cars 9 Minutes or less.
I agree, frequent oil and filter changes are the key to making your engine run well and keep running well.

I'd leave the sump plug out for longer than that, they must be using a pump. Don't like pumps.

Possibly, I don't know. What they do is a fast oil change and I am sure it is better than worrying if every last drop of oil is drained.
99% fresh oil and a new filter or old oil and an old filter?
Whats going to make the engine last better?

BTW most VW's pump oil better than drain.

Can't you get the DPF removed?

Only a matter of time until that is an NCT/MOT/XXX fail in all civilised countries.
Now, it could be 2 years or it could be 10 years in Ireland. Or never.

This is Ireland so never is most likely!

To play devils advocate; if didn't use the car much during the week for short trips and you mainly drove longish trips at the weekend with a full car (two adults, two kids and boot full), even if you don't do 20K kms a year wouldn't a diesel be more suitable?

Assuming regular servicing (same cost), tax saving offsets higher purchase price over 4/5 years.

Aye true enough I suppose, but to me it's like sticking your fingers down your throat when you're bloated rather than taking a good dose of castor oil.:pac:

It's a good excuse to get a look around the underneath too, and a bit of stress relief bucking about with the plastic undertray!

I agree with all your sentiments but the people that use those services are probably busy and don't get their hands dirty.
