Hi Michael,

If you want to go petrol then there are few better options than Volkswagen's 1.2 TSI turbo, and when it's fitted to the Skoda Octavia, you've got a near-perfect combination. Drive it gently, and you'll probably get very little difference in the overall fuel consumption compared to your old 407. That engine hasn't really been in the market for all that long, so it's a little hard to get a handle on whether or not there are any reliability landmines out there, but in general we've heard nothing bad.

Hi Geraldine,

It's always difficult to assess cars from afar, so we'd recommend bringing your car to a mechanic. Nonetheless, other things to check include the HT leads to the spark plugs, the cleansiness of the air filter and perhaps the fuel delivery system - the injectors or fuel pump.

Best of luck with it

Hi Wayne,

The Mii has a tank capacity of 35 litres, including a 'reserve' of four litres. That's when the warning beep occurs. Obviously how far the car will then drive will depend on a wide range of factors, so don't take a chance...

Hi Declan,

Don't worry about the handling - MINIs are terrific to drive. Great fun. The C30 is perhaps a bit less so and Volvo parts and servicing have always been on the pricey side, but it's a much more practical car than the MINI, which is seriously short on space. Both are fine cars though, reliable too so it's a question of what you value more - space and comfort (Volvo) or driving fun (MINI).

Hi Jane,

I have to admit I'm not a big fan of the current X3. Too hard-riding and not practical enough for my liking, although I'll grant you it's very good to drive. 

But, while the Outlander isn't the most exciting or dynamic vehicle around, it does have a few advantages. It can be had as a seven-seater, it comes with an eight-year warranty and Mitsubishis tend to be very reliable.

Best of all, for the price of an X3 you could get into the PHEV plugin hybrid Outlander, which is a properly ground breaking car. Get an E-Car charger on the driveway (you should still be able to get a free one if you're quick) and you'll be able to go 50km without using the petrol engine, but you still have a proper fuel tank on board for long journeys and can average 40mpg with the petrol engine going. 

Can't go wrong, really...

Hi Harry,

It's very difficult to assess such a thing remotely, but here are a few things to check:

1 - Are you carrying extra weight in the boot?

2 - Check your tyre pressures, condition and alignment - makes a big difference.

3 - Check the cleansiness of your air filter. Very important.

4 - Have it serviced if it has not been in a long time.

5 - Check that none of the brakes are binding - jack up each corner in turn and with the car out of gear and the handbrake off you should be able to freely turn each wheel. If not, the brakes may be binding and need to be looked at.

6 - Only when you've exhausted the simple stuff should you look into getting the car hooked up to a diagnostic machine. Some versions of the TDI engine had problems with injectors and turbos that could lead to higher fuel consumption, but the fix is expensive.

Hi Bill,

The trick will be to buy the newest one you can. The 2002 to 2010 E-Class was beset with all sorts of reliability issues, especially in its complicated electronics.

Your best bet is to get a current-shape E 200 CDI. It's a 2.1 but the low emissions and frugal fuel economy will keep your bills down. 

Expert answer

Hi Finian,

Possibly, but it depends entirely on the car and how you're driving it. If you're talking about a small diesel-engined hatchback, then yes, there's quite possibly a problem if you're only getting 19mpg on average. Even driven for only short hops around town, most would manage at least 35mpg on average. Certainly worth a visit to the dealer to at least have it looked at.

That said, the single biggest influence on fuel consumption is driving style. Have you changed the way you drive, or your regular route lately? Are you spending a lot of time idling at traffic lights where you previously weren't? It all adds up...

Expert answer

Hi Kieran,

Not massive. There's a tiny 1mpg gap between them in terms of fuel economy (the Toyota gets 59mpg, the Ford 60mpg), but in everyday driving , they'll probably work out pretty much the same.

Overall, the Toyota will probably be slightly more reliable, and the Ford slightly cheaper to service and repair if anything does go wrong. The Toyota will probably be a little cheaper to insure too, and its road tax will be slightly lower.

On balance then, the Toyota is likely to be fractionally cheaper to run, but there's precious little in it.

Expert answer

Hi Martina,

There are many possible reasons for this drop off in your fuel economy. Start with the easy things - you'd be surprised how important they are.

1 - Are you carrying extra weight in the car now than you were before? Golf clubs (or bricks!) in the boot? It can have a large effect.

2 - Have you fitted a roof rack/box? Again, can have a massive effect.

3 - Check the air pressure of your tyres. This is very very important. Underinflated tyres cause extra drag, requiring more fuel. Don't over-inflate either though, as that could lead to a blow-out. Follow guidelines for the car/tyre.

4 - It's winter so you're most likely using the lights, heater and demister a lot more. Those all use fuel. In particular, make sure you turn off the rear window demister when it's not needed - it uses a lot of energy.

All the above you can do for yourself, so do and then see if things have improved. After that we would suggest that you have your car serviced if it has been a while. The air filter and/or fuel filter could be clogged and it's a good time to hook the car up to a diagnostics machine to see if there are any error codes indicating other issues.
