  Classic owners face introduction of higher ethanol fuel by end of 2019 (Article)
  But E10 unleaded petrol that contains 10% ethanol is potentially harmful to classics. According to the Government, around 800,000 vehicles would not be compatible with E10 fuel. However, the Society of Motor Manufacturers and Traders (SMMT) puts that figure closer to 1.4m – nearly double Whitehall's estimate. Using E10 fuel in a classic can cause blockage to fuel filters, damage to fuel pumps as well as causing fuel hoses to degrade and a host of carburettor problems.
• MISFUELLING A CAR: What should you do if you accidentally put the wrong fuel in your car?  (FAQs)
  This can lead to a lack of lubrication for the engine – much like actually running out of oil. Diesel Cars: Petrol is corrosive in a diesel fuel system, attacking the rubber hoses and seals and the plastic fuel tank itself. It strips the lubricating effect of diesel fuel, and this can cause damage to the low pressure fuel pump, the high pressure fuel pump and the injectors.
• DIESEL v PETROL: Which is better for me?   (FAQs)
  Europe has more diesel then the UK because it can store more, which is why diesel is dearer in the UK than in Europe. UK fuel tax on petrol and diesel is the same at 50.35p per litre + VAT, + VAT on the fuel itself. Fuel Duty on Petrol and Diesel = 50.35p/litre Fuel Duty on Biodiesel = 30.35p + 2p = £32.35p Fuel Duty on Bioethanol = 30.35p + 2p = £32.35p Fuel Duty on LPG = 16.49p/kg + 4.28p/kg = 20.77p/kg Fuel Duty on CNG = 13.7p/kg + 2.89p/kg = 16.59p/kg Fuel Duty on Red Diesel = 9.69p + 0.38p = 10.07p Fuel Duty on Fuel Oil for heating = 9.29p + 0.37p = 9.66p 
• Fuel Calculator (Article)
  It features every make, model and trim of car on the UK market. How do I use the   Fuel Calculator? The Fuel Calculator is simple and easy to use. Basically, it compares two cars to find the lowest fuel cost, whether it's petrol or diesel, hybrid v electric, petrol v electric or any combination of these.
• FUEL ECONOMY: What MPG should I be getting from my car? (FAQs)
  Then do at least 250 - 300 miles, fill up again to the brim and note the mileage on the receipt. Subtract mileage 1 from mileage 2. Then multiply the litres of fuel on the 2nd receipt by 0.22 and divide the answer into your mileage. Continue brim-fill after brim-fill. Though this depends on odometer accuracy, it will give you a better idea than the car's fuel computer which is a notoriously inaccurate accessory on any car.
• FUEL: What are the benefits of running a vehicle on Superunleaded or Superdiesel? (FAQs)
  So manufacturers 'optimise' their engines to give the best possible performance in the tests and, to achieve this, they optimise the engines to run on Super. Engines will still run on lower Octane and lower Cetane fuel, but not as efficiently, not as cleanly and will be more prone to damage from deposits such as olefins and carbon left inside the engines. If vehicles are driven to take best advantage of Super, which means changing up earlier (at low throttle openings a properly programmed automatic will do this for you), then the improvement in fuel economy is usually between 4% - 6%.  Where Super is sold at up to 8p more than ordinary 'Premium' fuels, the improvement in economy usually covers the increased cost.
• Real MPG (Article)
  Real MPG was created after we received thousands of complaints from readers that their cars could not match the official claimed fuel economy figures. Unlike laboratory tests, Real MPG gives real world data from real drivers and allows owners and buyers to see how much on-the-road fuel a vehicle really uses.

  Top 10: Winter tyres (Article)
  Rated C for fuel consumption, E for wet grip and a noise rating of 71dB, the WinterCraft comes in at £105.35 fitted. Bridgestone Blizzak LM005 An impressive all-round winter tyre from Bridgestone, the Blizzak manages a C rating for fuel consumption while also achieving a superior A rating for wet grip.
• LPG: Where can I get my car converted to run on LPG? (FAQs)
  Although UK fuel has a higher energy coefficient, it burns hotter and places the engine under correspondingly greater stresses. Worse, because it is not filtered as effectively as continental fuel, there have been numerous instances of component failure arising from unfiltered inpurities.
• DPFs: What are they and why do they go wrong? (FAQs)
    .Second post-injection injects fuel late in the power stroke cycle; fuel partly combusts in the cylinder but also sweeps down the exhaust where unburned fuel triggers an exothermal event in the catalyst, raising the filters temperature further.

  Review: Bridgestone Turanza 6 tyres (productReview)
  But perhaps the biggest thing we noticed with the Turanza 6 tyres was an improvement in fuel economy. Our 3.0 TDI Audi Q7 saw a 5mpg improvement in fuel consumption over our 2500 miles of testing. Given that it usually only returns around 32mpg, that's a significant change and one that means a healthy saving in fuel costs.

  Review: Suzuki GSX-S125 (productReview)
  The LCD panel includes a segmented-bar tachometer across the top, a digital speedometer, gear position indicator, digital clock, digital odometer with dual trip meters, an average fuel consumption meter, a fuel gauge and an oil change timing indicator. A lot of new riders want to be able to put both feet flat on the ground when the bike is stationary to gain a bit of confidence.
• STORING A CAR: How should I prepare my car for long term storage? (FAQs)
  (With a mild steel tank condensation can bring a rust problem.) The disadvantage is the weight of the fuel on the springs and on the tyres. If leaving for years, then fuel with high moisture bio content may partially emulsify, so empty the tank and insert some dessicant strips via the sender pump access panel to absorb the condenstation.

  . The Continental do well in wet and dry conditions too with reliable, reactive braking and the tyres are also very quiet and refined even at high speeds. They're also very fuel efficient."  
• ENGINE ECU: Where can I have the Engine Control Unit (ECU) of my car re-mapped? (FAQs)
  Electronic engine management systems in new cars are compromise programmed to provide reasonable performance and emissions and in a wide variety of weather conditions on a wide variety of fuels. They are also programmed to give best fuel ecomomy in the specific EU fuel consumption comparision tests performed in laboratory conditions. That means the manufacturer programme may not be ideal for the conditions in which you will be driving the car and leaves plenty of scope for improvement.

  Review: Honda Versatool (productReview)
  We didn't fill the tank completely due to the weight, instead, we filled about 1/3 - which didn't make the Versatool too heavy when we were cutting the hedge. It's worth bearing in mind we're 5'7" and not very stocky, so the 6kg (without fuel) machine won't be too heavy for those who it's probably aimed at. However, when using the hedge trimmer or any other attachment in which the Versatool is pointed upwards, the fuel will sit at the back of the tank away from the fuel pipes if it isn't topped up enough - meaning the Versatool will stop running.
• RUNNING IN A DIESEL: What's the best way to run-in a diesel engine? (FAQs)
  On passive cycle the DPF will require the car to regularly be driven significant distances at 2,000rpm plus for the DPF to get hot enough to regenerate and burn off the particulates in it. DPFs also have an 'active' cycle where additinal fuel is injected into the combustion chambers to creater hotter than normal exhaust gases to burn off particulates in the DPF. However, this does not always work and the extra fuel can instead find its way into the engine sump, contaminating the lube oil and sometimes leading to such a rise in sump oil level that the engine can start to run uncontrollably on its sump oil and will self-destruct.

  Halfords service costs and plans (Article)
  A car that isn’t afforded regular maintenance is more likely to break down, less likely to pass an MOT and may even use more fuel and therefore cost more money to run, so ignore the service schedule at your peril. If you don’t know what you’re looking for when seeking out a car service provider the reassurance of a well-known name like Halfords can be a great help.
