James Ruppert: Two fuels are better than one

I know this sounds pretty obvious, but apparently UK drivers now consider what actually moves their purchase – the powertrain, to anoraks – to be the most important factor during the purchasing process, according to automotive video and retail company CitNOW. 

Once upon a time, there was just one option, petrol, and it would only be diesel if you drove a lorry or a taxi. But these days, there are all sorts of exciting options and 43% of motorists now view the choice between petrol, diesel, hybrid and electric vehicles as the most important factor. So despite what our road testers might tell you, it’s what goes in the tank that is important. But the thing is there are overlooked sources of motive power. 

Liquid petroleum gas: I’m a fan. Not enough of a fan to buy one. My biggest problem is always who actually did the installation, which is not a simple thing to get right. Mind you, dual-fuel manufacturer conversions were a thing a decade or so ago. Let’s start with an easy one, a Ford Focus 1.8 FFV Style from 2010. It is £2999, but the hassle of finding any E85 ethanol fuel should put you off. Never mind, because Volvo also did the dual-fuel thing. But with gas. 

Answer: If the tyre hasn’t been damaged or driven for any great distance, it is possible to repair it. Reputable tyre fitters abide by British Standard AU159G, which sets out clear repair guidelines. It states that a puncture in only the central three-quarters of the tyre can be repaired. Some runflat tyres can be repaired but most fitters refuse to because runflats’ extra strength can conceal hidden internal damage. John Evans
