Hi Shane,

If it's a small petrol hatch you're looking for then I think the best options are either a Ford Focus with the 1.0-litre EcoBoost turbo engine (the 100hp version is the sweetest) or either one of the three Volkswagen Group hatches (Golf, Skoda Octavia or SEAT Leon) with the brilliant 1.2 TSI turbo. Both engines, if driven gently, should yield close-to-diesel fuel economy.

Incidentally, your point about higher seats being easier to get in and out of for elderly drivers is well made. It might be worth checking out something nearly-new along the lines of a Golf Plus or Ford C-Max in that regard.

Hi Stephen,

I agree it can be a little annoying on an automatic car, as you can't decide when you do and don't want it to happen at any given moment. I'm sure you're aware that there is a button on the dashboard to disable it at any time, but it sounds like you'd rather disable it completely. Sadly, there's no legitimate way to do this. The car's official CO₂ emissions and fuel economy figures rely on this feature, so even if you find a fuse or relay to remove for the system there will at the very least be a warning light on in the dashboard - and it may even go into 'limp home' mode.

By way of explanation, the 'combined cycle' is a relatively low-speed and short duration (standardised) test cycle all the car makers adhere to for their CO₂ and fuel consumption figures. Stop-start makes a big difference for this as the car is idle for considerable amounts of time. In the real world, this tends to happen only in slow traffic or in town with lots of traffic lights. You would see a saving in those situations, but in reality it'll be small.

Sorry not to be of more assistance.

Hi Gerry,

You've picked three difficult cars to choose between. Obviously, both the Hyundai and Kia are essentially the same car beneath the skin, and both come with temptingly low prices and long, long warranties. The SEAT's three-year warranty looks a bit brief in comparison, but then you are buying into a car with excellent reliability and high quality, so there's that.

You've also got an odd combination of relatively high mileage, but in an urban location, which suggests that you won't be working up enough speed to generate exhaust heat to keep a diesel particulate filter (DPF) clean. With all that in mind, I think your best best might be a Leon 1.2 TSI petrol. It's a cracking engine, nearly as good as a diesel on fuel economy, but with no nasty surprises waiting in the exhaust. Both the Hyundai and Kia are excellent cars, but both are best experienced as diesels.

Hi Gary,

There is no adjustment to be made. We spoke to Honda Ireland about this and it's suspected that fuel contamination and/or a blocked fuel filter is to blame.

First thing to do is change the fuel filter, clear the code and try it again. Honda says it would normally look at what is in the old fuel filter before running the car again, as it may reveal a need to drain and clean the fuel tank.

Let us know how you get on

Hi Nelius,

Cracking car the original Mazda6. One of the best-to-drive saloons ever built and the good news is you're looking at mostly pros, and very few cons. The only real mechanical weak point is the clutch - we've heard of them failing at as little as 50,000km so check to make sure that the action is smooth and not too heavy and that the gear changes are crisp and quick. Any slipping or smell should set off alarm bells.

Other than that, there are a few recalls that you need to make sure were attended to (leaky fuel lines, dodgy fog lamps, brake warning light and oil seals) and it's worth checking to make sure that the suspension and steering are in good fettle and that there's a good set of high-quality tyres on the car; the better to enjoy that wonderful handling balance.

Hi Kevin,

We've done a bit of digging into this and... there is no good answer. As a general rule of thumb, a USD$2 fall in the price of a barrel of oil should translate into a fall in the price at the pump of between 1.5c and 2c. Since June, the price of a barrel has fallen by, as you point out, USD$18 so where's our 18c cheaper litre of petrol? Answer: no-one's saying.

All the oil industry analysts are pointing to a weaker global price for crude oil, in spite of the recent and current turmoil in the Middle East. US reserve stocks are up, usage in China is down a little, all of which puts the price of oil under pressure. 

In fact, the price of a litre of petrol in the UK, which takes its feed from the same Brent Crude contract as us, has fallen by a few pence per litre recently, but in Ireland the price has actually gone up by 2c on average. Inflation? Nope, that's not the cause - the Central Statistics Office has inflation pegged at a lowly 0.4 per cent right now.

So, are the oil companies and distributors just gouging us? Possibly, yes. None of those contacted for an explanation deigned to respond, and there has been no increase in fuel duty nor carbon tax from the government side so the only logical explanation left is... yup, gouging.

All we can suggest is to do the usual - shop around and try and find the best price you can. There's no point in popping across the border, sadly - the UK's price of around STG£1.29 for a litre of petrol equates to around €1.64 and that's before bank transaction charges.

Come on Apple Green, Texaco, Maxol, Topaz et al; your input cost has fallen significantly. Why aren't we consumers getting the benefit?

Expert answer

Hi Kevin,

Because, unfortunately, there is always a lag between the price of crude oil falling and the price coming down at the pump. It’s rarely the case going in the other direction of course, but before you go blaming rapacious fuel companies remember that the actual wholesale price of oil represents only a tiny fraction of the price of a litre of pump fuel – most of it is fuel duty and VAT. In fact, according to the AA, the price is on the way down. The average price for a litre of unleaded has fallen by 5c since June, and the average price for a litre of diesel has fallen by 3c.

Hi Kieran,

With that kind of mileage, you could probably look at saving yourself a bit of money by going for a petrol model - as long as the price gap between it and a diesel covers the fuel cost. Get your calculator out...

Of the cars you've mentioned, we'd go for a 3 Series. Few cars are as good to drive and it's the kind of thing you should own once at least. Check it carefully for wear and tear though and don't buy anything without a full service history. 

The only catch could be trying to find one that ISN'T a diesel...

Hi Mark,

Right, obviously it's always a bit of a scare when you slip on the road and damage your car, and it's natural for the reaction to be "I'd better get a 4x4." Hang on though, because there are 4x4s and 4x4s... First off, the Tuscon. According to the official figures, the 2.0-litre diesel 4x4 Tuscon does 39mpg while the 2.0-litre petrol model does 35mpg. We'd bet that you'll struggle to match those figures on the road and will instead get around 30mpg on average. Also, 4x4 Tuscons are a little tricky to track down in Ireland.

So, as an alternative, why not consider a Skoda Octavia 4x4? You know you like the car, the all-wheel drive system is just as good at finding traction as any big SUV's and the lower, lighter body means you won't pay as heavy a fuel consumption penalty. We've found one for sale on Carzone for just over €10k, so they're not even too expensive.

Worth a look, at any rate.

Hi Bernard,

An individual injector is going to cost in and around the €170 mark, depending on where you source it from. After that, it’s down to the garage you bring it to and what kind of labour rates they charge.
