If your car needs new tyres you might be shocked at how much replacement rubber can cost. But while often cheaper than new, buying second-hand tyres can have serious safety implications. New research has found that nine out of 10 retailers selling used or part-worn tyres are trading in illegal rubber.

Charity TyreSafe and Trading Standards have spent the past five years investigating part-worn tyres on sale in the UK. They discovered that just 13 of the 152 dealers they visited were selling roadworthy tyres. TyreSafe chairman Stuart Jackson said: “As far as we’re aware there is no other retail sector with such an atrocious track record.”

Unnecessary work

Has a garage recently suggested you need new brake fluid, an anti-freeze drain and refill or a fuel and oil flush? If so, how do you know whether it had to be done or was unnecessary work? Research by Green Flag has revealed that UK drivers spend £3.4billion every year on work by garages to their cars that doesn’t need doing. That’s around £90 per car per annum.

The problem stems from drivers not having the knowledge about their cars to question whether work recommended by garages is really required. More than a third of drivers (39 per cent) say they have no idea what’s checked when their car has its annual MOT roadworthiness check. But this is when garages often say jobs need doing.

Read on to discover which 10 jobs Green Flag believes should ring alarm bells if they’re suggested by a garage. And find handy hints on how to check whether the work really should be done.

Expert advice: how to replace a car’s battery

We usually think that cold weather takes its toll on car batteries and causes them to fail. But it’s frequently hot weather that does the damage. Heat dries batteries out, causing them to lose their charge more quickly.

Then when temperatures fall, oil thickens up, it takes more current to turn an engine over to start it, the battery struggles to perform as it should and eventually fails.

One thing’s for sure: no one wants to be stranded with a dud battery. Bearing that in mind, it’s a good idea to think about replacing your car’s battery when the weather starts to cool. Here are some tips on doing that.

What kind of battery does your car need?

Know your car jargon, learn to speak mechanic and don’t get ripped off

car jargon

Every industry has its own language; jargon that only the people working in the business understand. The car industry is no different. We’ve all had a mechanic take one look at our car, shake their head, suck air through their teeth and mutter something using words that might as well be in another language.

The result is people don’t trust garages. One study found that nearly half of drivers think technicians hiding behind confusing car jargon have ripped them off. According to property company Pentific, mechanics rank alongside politicians, car sales execs, journalists, estate agents and builders for being untrustworthy. But you need never be baffled again. Here we explain six pieces of commonly-used car jargon.

Dangerous bacteria

All sorts of nasties can come out of your car’s air-con (Picture iStock/Humonia)

Do you know what’s living in your car’s air-con? You may never have considered it but a car’s air-conditioning system is a haven for bacteria. Scientists have even discovered that some of the bugs can be dangerous, leading to meningitis, urinary tract infections and sceptic arthritis.

Our expert has already written this useful guide on why you can’t expect air-conditioning to work effectively if it’s not regularly serviced. But new research has found out exactly what inhabits our air-con. In America, where air-con has been common in more vehicles for longer, they even have a name for the effect that exposure to these bacteria can have: Sick Car Syndrome.

Having a windscreen repair or replacement will factor in most our motoring lives at some point. Road debris flung up by vehicles in front or falling from bridges above can result in windscreen damage. Whether it’s a miniscule chip or a more substantial crack, the question for most of us is does our screen need repairing or replacing?

How you react to a damaged windscreen depends on the type of damage the screen has sustained. Some can be repaired but in other cases the screen must most definitely be replaced. Read on to find out what you might need.

Most drivers don’t know about 2018 MOT changes, Green Flag finds

MOT changes

The MOT test changes this weekend but you can be forgiven if you didn’t know. New research conducted by Green Flag reveals that six out of 10 drivers (58 per cent) haven’t realised the MOT changes are happening.

More worryingly perhaps, nine out of 10 drivers (89 per cent) are unaware that driving a car with an invalid MOT might result in a £2500 fine. And a quarter (25 per cent) don’t realise that driving a faulty vehicle results in a penalty. Read on to find out more about the changes and how drivers might be able to save themselves money.

Expert advice: Finding and fixing a broken fuse in your car

Broken fuse

Being able to fix a broken fuse in a car is one of the handiest pieces of knowledge any car driver can deploy. At some point in your motoring life a fuse in your car will blow. And very often you don’t need to pay an expensive motor mechanic to fix it.

You should be able to tell instantly if you’ve got a blown fuse because a function that you take for granted will stop working. It might be the 12-volt power socket, the windscreen wipers or the indicators. If it is the fuse that’s causing the problem, you may be able to fix it in a couple of minutes with a part that costs pennies rather than paying a mechanic. Here’s how.

Expert advice: what an engine warning light means and what to do

Engine warning light

This March we saw a significant increase in the number of customers ringing us with their engine warning light on. These faults were up by more than a third (39.3 per cent) compared with February.

Warning lights can be worrying and frustrating in equal measure. They’re a worry because they indicate trouble. And when things go wrong with cars, it usually costs money. They’re frustrating because while the lights reveal a fault, they don’t tell you exactly what the problem is. Here’s what you need to know.

How to report an intermittent fault on your car to a garage

Intermittent fault

Sometimes technicians need to go to extreme lengths to find a fault in a car (Picture iStock/Boschettophotopgraphy

The older cars get the more likely they are to develop faults. And the worst of those is the intermittent fault; a noise or problem that’s there one minute, gone the next. The temptation for many of us is simply to tell the mechanic there’s an occasional rattling noise at the front and let them get on with it.

That’s fine but you wouldn’t go to the doctor, say you’ve got a pain in your leg and expect them to instantly diagnose the correct malady. And unlike most doctors, mechanics charge by the hour, so leaving them to find out what’s wrong will cost you.

But even the least mechanical people can make the technician’s life easier. And by doing so, they may even save themselves some money. Here’s how you should go about reporting an intermittent fault with your car to a garage.

Think like a pilot: drivers urged to carry out ‘pre-flight’ safety checks

It’s a funny advert with a serious point. A family boards its flight for a holiday. Over the tannoy the pilot explains he hasn’t bothered making any pre-flight safety checks to the plane. Cue panicked faces and unbuckled seat belts as everyone scrambles to leave.

The ad has been produced for Highways England. The organisation, responsible for the safety and management of the nation’s main roads, is trying to raise awareness among drivers to perform safety checks to their car before every journey.

The logic is sound. Driving is inherently more dangerous than flying. So why would you get into a car without knowing that crucial things like its lights, wipers and tyres are all working or safe?

Expert advice: why cold weather plays havoc with car suspension springs

Suspension failure

You probably don’t imagine cold weather and car suspension failures go hand in hand, but they do. During December, Green Flag witnessed nearly six times as many call outs for front suspension problems as in November. The number from December 2017 was up by nearly a quarter (24 per cent) compared to the same time the year before.

For our customers, this represents a significant problem. There isn’t just the cost of having expensive suspension parts replaced. It’s the inconvenience of the problem occurring in the first place. That’s because broken suspension isn’t usually a roadside fix: cars must be recovered to garages to be mended. Read on to find out more about this phenomenon.

How do you know if your suspension is broken?

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?
