Diesels less reliable than petrols and pricier to fix, report claims

Diesels less reliable

As if diesel didn’t have enough on its plate, now experts are saying that cars powered by the fuel are less reliable than petrol motors. The majority of complaints around diesel have been down to its environmental credentials. However, a new report shows that diesel cars could be three times more likely to break down than their petrol equivalent and up to 20 per cent more expensive to fix.

How unreliable are diesel cars?

Modifying cars: what can you and can’t you do?

Modifying cars

Once upon a time this would have been a humble family runabout…

We all like to give things our personal touch and modifying cars is no different. But while it might please you to make parts of your car bigger, brighter, faster and louder, it could land you in hot water.

For a start, the law takes a dim view of cars that aren’t considered roadworthy. And insurers may even refuse to pay out if you modify a car without telling them. Here we look at what you can and can’t do to your car. And whatever you decide, make sure you do it with safety in mind and that you inform your insurer.

Changes to the 2018 MOT: diesel cars face stricter emissions test

Changes to the 2018 MOT: diesel cars face stricter emissions test

Changes to the MOT will come into force this May, making it more difficult for dirty diesel cars to pass air quality tests. A three-tier rating for the severity of faults on all cars will also be introduced.

The Driver and Vehicle Standards Agency (DVSA) claims the revisions to the MOT will make it tougher for anyone trying to cheat emissions tests and help keep vehicles in a dangerous condition off the road.

However, at the same time hundreds of thousands of cars more than 40-years old will no longer be required to take the annual road worthiness inspection. Here’s what motorists need to know about the changes.

Expert advice: should I choose synthetic or semi-synthetic oil for my car?

Synthetic oil

Back in the day, oil was oil. It came out of the ground and as long as it was the right viscosity for the engine, we’d trust it to do the job. Now there are effectively three kinds of oil: mineral, synthetic and semi-synthetic. And I’m frequently asked: “Should I use synthetic oil for my car?”

I’ve already spoken about the grade of oil drivers should choose for their cars. But once you’ve decided on that, what are the benefits of synthetic oil?

Driver tips for staying safe as snow falls and winter weather worsens

Driver tips

Cold weather isn’t just tough on drivers, it can play havoc with cars too. The heavy hail and snow showers that are hitting parts of the UK in mid-January 2018 are already causing chaos. Green Flag is warning that an astonishing 12 breakdowns every minute will take place this week.

Head of news for Green Flag Simon Henrick said: “After a variable but relatively mild winter period over Christmas, the changing weather conditions may take some drivers by surprise this week.

“By thoroughly checking their cars before leaving home, approaching the roads with caution and keeping plenty of distance between themselves and the vehicle in front, drivers will decrease the risk of encountering a problem while on the roads.” Read on to see how you can stay safe in the snow.

Expert advice: are faulty glow plugs the reason your car won’t start?

Glow plugs

When is a flat battery not a flat battery? When it’s a problem with glow plugs. OK, that’s a bit simplistic but frequently people breakdown with what they think is a battery problem, only for it to turn out to be the glow plugs that are at fault.

The reason is that diesel engines use these heaters to help them start. In warmer weather they’re not as necessary. However, when the weather gets cold, glow plugs are vital. That’s why in November 2017, the number of call outs Green Flag attended for glow plug problems rose by 112 per cent. Read on to find out what the problem is and how you can diagnose it.

Choosing a replacement exhaust: what to look for and why to shop around

Choosing a replacement exhaust: what to look for and why it pays to shop around

If your car has ever needed a replacement exhaust you’ll know just how expensive this essential mechanical component can be. As it’s such a pricey part, it pays to know what to look for and it’s important to shop around. That might seem daunting, but the potential price savings alone should convince you research is time well spent.

The exhaust is an essential part of your car. It keeps the engine healthy and ensures the emissions being pumped out do as little harm as possible to the surrounding environment. But over time, the effects of high temperatures, water and grime, the occasional bash from a speed hump and general wear and tear from continuous movement mean it can end up needing replacing.

Here’s the exhaustive low down on repairing or replacing a car’s exhaust.

Expert advice: drivers rely too much on TPMS tyre pressure monitoring

Tyre pressure monitoring

If your car is registered after 2012, it will probably be fitted with a Tyre Pressure Monitoring System (TPMS). But I have concerns that drivers are relying too much on the technology and not performing regular tyre checks themselves.

My fears are that drivers could be putting themselves in danger by thinking TPMS is doing a job it is neither designed for nor capable of. Here’s how TPMS may not be the all-encompassing safety net many drivers think it is.

TPMS MOT failures rise dramatically

All you need to know about coolant and antifreeze for your car

Coolant

The colder the weather gets the more drivers should consider the coolant in their car. This is because engines need liquid circulating through them to keep cool. But freezing weather can turn that fluid to ice, rendering it useless.

Coolant is vital because when a car is going at speed, pistons travel at around 40mph, shafts whizz round and bearings are under extreme pressure causing heat to build up. To stop this becoming so intense that metal parts begin welding themselves together, coolant is used. Here’s all you need to know about it.

Is coolant the same as antifreeze?

MOT 2018: what the changes are and what they mean for drivers

MOT changes

Next year the UK government is planning to bring in MOT changes. The tweaks to the annual vehicle roadworthiness test have been designed to make life easier for drivers preserving historically interesting ‘classic’ cars.

But critics say they will increase the number of unsafe cars on the country’s roads. Further changes are afoot too. The Driver Vehicle Standards Agency (DVSA) is currently considering the results of a consultation paper on the age that cars first take their MOT. Read on to find out more about the changes.

Lost car keys: what to do and who to call

What to do if you have lost your car keys

A car is of no use without its key. It can’t be opened, so it’s going nowhere. And if it was locked and left in gear with the handbrake applied, it’s going to be devilishly difficult to move.

The moment most drivers realise they’ve lost their car keys, is when they need to be somewhere, soon. But first they’ve got the headache of working out how best to remedy the situation. Should they phone a friend who knows their way around a car? Perhaps it’s better to call a garage or should it be a breakdown service provider? And what about a car locksmith? Here are the steps drivers can take when they have lost their car keys.

Expert advice: Simple car care tips for young drivers leaving home

Car care tips

Going off to college can be a great adventure. Our tips will help ensure your car doesn’t spoil it

I’m sure there are some exceptions to every rule, but I’ve never yet met a student who’s rolling in money. And running a car that keeps on conking out can be like having a hole in your pocket. The key with cars is prevention rather than cure. Keeping on top of regular maintenance will prevent all manner of mechanical mishaps.

But more than that, a regular maintenance routine will actually help save you money. Tyres that are properly inflated don’t wear out as quickly and mean your motor won’t use as much fuel. And having the oil and filters changed when the maker suggests will guarantee your car performs as economically as possible. Read on to see my top car care tips.

Tuned to perfection: how to upgrade an old car stereo to stream music

Tuned to perfection: how to upgrade an old car stereo to stream music

It’s a fact that the average age of a car in the UK is almost eight-years old. Given that millions more motors will be older still, many drivers are singing along to car sound systems that pre-date music streaming using Bluetooth. Plenty more are driving cars from a time when an apple was something you ate.

If that sounds familiar, there is some good news: it’s possible to upgrade an old car’s sound system. This means you’ll be able to play your latest digital music collection, or even use music streaming services, such as Spotify.

A wide range of clever accessories is available, and upgrades start from as little as £10. You might be keeping an old car going to get maximum value for money from it. Or you may own a classic car that’s from a time before iTunes. Whatever’s the case, you can use modern technology to upgrade your car’s sounds. Here’s how to put an end to the days of doing the time warp.

How do you play music from a smartphone with a cassette player?

Expert advice: what to do with an overheating car

Overheating

Overheating cars used to be a familiar sight, stopped at the road side, bonnet up, steam pouring from the engine. Thankfully it’s not so common now as cars in general have become more robust.

But overheating – when the engine’s water literally boils – does occur. Here we look at why, what you can do if your car does overheat, and offer some tips on how to prevent it.

Video revolution should help drivers get fairer deal from garages

video

New tech is designed to let mechanics show you what needs fixing without you being there

A virtual revolution is taking place in the UK’s garages with video becoming a workshop must have. Garages film what needs repairing. They can then show this to customers and seek approval before doing the work. The idea is to give car owners more control over repairs and reassure them that they’re not being ripped off. Here’s how it works.

Why video technology is needed

For most drivers, the dodgy reputation garages have is a worry. Recent research by online garage booking service BookMyGarage found that three quarters (74 per cent) of drivers felt hidden costs or paying too much for extra work were the biggest concerns when taking their car to a garage for its regular service. Drivers fear that unscrupulous operators can use superior mechanical knowledge to bamboozle them into repairs that don’t need doing. Continue reading

Polished with pride: the best way to spring clean a car

Polished with pride: the best way to spring clean a car

The birds are singing, the bees and buzzing and the bulbs are flowering: Spring is in the air. And that can only mean one thing; many of Britain’s drivers are looking at their car and hanging their heads in shame, unable to remember the last time they cleaned their motor.

If that sounds familiar, set aside a couple of hours one weekend, roll up your sleeves and treat your car to a thorough spring clean. Pick a sunny day and you might even put some colour in your cheeks.

You don’t have to be a professional car valeter, or detailer, to return a car to the showroom-sparkle finish it once enjoyed. Here are some simple tips to take the strain out of a spring clean.

Choosing the best hands-free Bluetooth phone or sat nav kit

Choosing the best hands-free Bluetooth phone or sat nav kit

Keep your eyes on the road and hands on the wheel with voice-activated smartphone kits

The law on mobile phone use in cars changed at the beginning of March. The penalty for drivers caught phoning or texting without being hands-free has doubled, to six points with a £200 fine. But there’s no need to be hit with a costly fine and hefty points. There’s plenty of aftermarket equipment that will keep drivers on the right side of the law and safe on the road.

Bluetooth integration for mobile phones first made its way into our cars in 2001. For years, it remained an option that drivers would have to pay for with their new car. These days, it’s widely available as standard.

For anyone driving an older car without Bluetooth, there is a wide range of products to choose from, some offering much more than just wireless connection to a phone.

Revealed: Britain’s staycation hotspots where drivers are most likely to get a flat battery

Revealed: Britain's staycation hotspots where drivers are most likely to get a flat battery

As millions of British families enjoy a staycation during the first half term of 2017, experts at Green Flag are warning drivers to beware of being left stranded by a flat battery.

Whether staying at home or exploring a new part of the UK, this week will see huge numbers of drivers park their car and leave it until the half-term break comes to an end. But in the current wintery weather, many of those cars won’t start for the journey home because of a flat battery.

This Saturday (18 February) is National Battery Day. And Green Flag’s expert technicians expect to have to ride to the rescue of 2800 drivers whose car batteries have packed up.

Simple tips to prevent a flat battery in a car

Simple tips to prevent a flat battery in a car

On the face of it, a car battery is a boring piece of equipment that’s often hidden away and rarely given a moment’s thought. But drivers who don’t want to end up stranded at home or, worse still, at the roadside should pay more attention to their car’s battery, or it could go flat.

It’s no exaggeration to say that the battery is the heart of a car. If it goes flat, your car stops working. And flat batteries are the number one cause for technicians from Green Flag to be called out to rescue drivers.

The reasons car batteries are the number one culprit causing breakdowns are simple. Batteries don’t last forever; they typically have a working life of between five and seven years. And batteries are placed under increasing strain, as new cars offer a rising number of convenience features that can drain them with precious little warning.

Happily, you don’t have to be a trained technician to care for a battery. These are the simple steps any driver can follow to prolong the life of their car’s battery. Continue reading

Car exhaust cleaning: are DIY products for DPFs worth it?

Car exhaust system cleaning: is it worth using DIY products for catalytic converters or diesel particulate filters?

Within your car’s exhaust system there are two areas that are hot spots for trouble and often need cleaning – the catalytic converter and the diesel particulate filter. Both of these cause problems for the efficient running of your car and can lead to it failing its MOT. In fact, Britain has a monthly peak of 43,000 cars failing the annual roadworthy test because of unacceptably dirty emissions from the exhaust.

Given the high cost of replacement parts, it’s no surprise that many drivers are embracing DIY cleaning products. These claim to return to good health congested catalytic converters or diesel particulate filters. We look at the options for drivers and ask whether they are worth using.
