Diesel Tuning & More: Improving Gas Mileage


More and more frequently, consumers are looking for ways to improve their gas mileage. One of the most obvious reasons for this is financial in nature. With escalating gas prices, the expense of driving can quickly become a burden. Vehicles with poor gas mileage cost more money at the pump because they must fuel up more frequently than cars that are fuel-efficient. The environment is another reason to improve gas mileage. Cars produce carbon dioxide, a greenhouse gas that is a major contributor to global warming. The more gas a car requires, the greater impact it has on the environment. Whatever the reason, drivers are looking for more ways to improve fuel efficiency. Fortunately, basic changes can go a long way towards improving one's gas mileage.

Driving More Efficiently

How a person drives when behind the wheel directly impacts the fuel efficiency of the vehicle. For example, pressing on the car brakes too often, also known as riding the brakes, will reduce a vehicle's gas mileage. Gunning the engine at a green light is another behavior that detracts from a car's gas mileage. Drivers should also consider how much they carry inside of their vehicles. Operating a car with excess weight reduces its gas mileage as well.

Keeping Your Car in Shape

Most people recognize that proper vehicle maintenance is critical in keeping a car in good working condition. In addition to that, maintenance will also improve a car's gas mileage and fuel efficiency. Daily maintenance, such as checking the air pressure in all four tires, will contribute to better gas mileage just as changing the oil or replacing a dirty air filter will. When changing the oil, checking the vehicle's owner's manual will tell the owner the correct grade to use. An illuminated "check engine" light warning may also indicate a problem, such as a faulty oxygen sensor, that can reduce a vehicle's fuel efficiency.

Planning & Combining Trips

A driver with a plan is more likely to get better gas mileage than a driver without one, even if they drive the same vehicle. When a driver makes multiple trips throughout the day, he or she is burning more gas than drivers who have planned out their travel. The latter will have determined where he or she needs to go during the day and will plan to do all the necessary driving in one outing. This saves gas because a car that cooled-down engine will consume more fuel than a car whose engine stays warmed up.

Choosing a More Efficient Vehicle

Certain types of vehicles get better gas mileage than others, making them a good option for people who are replacing an older car. When buying a car from a dealership, the consumer will be able to look at what is called a fuel economy label. This label informs buyers of the vehicle's estimated average city miles per gallon (MPG), the highway MPG and the combined MPG. The label also indicates the annual fuel cost and the fuel costs savings compared the other average vehicles of the same model year. Newer labels also compare fuel economy and greenhouse gas rating with vehicles of the same model year. Another option is to purchase an alternative fuel vehicle, such as hybrid, electric, biodiesel, or hydrogen fuel cell vehicle.

“I must say l'm delighted with the improvement from your chip, its on the standard settings and the difference in the car is amazing!!! I have a smile on my face every time I get in the car, and there is about 5-7mpg improvement. With the mileage l do, l can see myself getting my money back in no time at all. So if your a doubter like me, don't be because its one of the best things l've ever bought!!!”

“Many thanks for your fantastic service! Unit ordered Sunday, delivered Tuesday am!! Unit now fitted and, as promised, the car is transformed. Winding country lanes tackled quite happily in fifth gear. Cruising on much smaller throttle openings and immediate response on acceleration. The car behaves as a mini car should behave. I had some initial doubts about spending quite a large amount of money on this item but it is worth every penny and would not hesitate to advise anyone to do similar.”

“A good product and a good service deserves recognition: I fitted a CHIP Express unit to my Insignia. What an amazing bit of kit! My fuel economy and performance went way up and with the mileage I do was a Godsend! On a run to Aberdeen from Hull I returned an average of 62 MPG and I drive quite energetically! I've just taken up the trade in offer and saved a few quid on a new system. The Vauxhall has now gone with 125,000 trouble free miles and I have changed car to a Volvo S60 D3. I'm looking forward to fitting the Chip Express unit and reaping the rewards, thanks guys!”

Vauxhall Insignia MK1 2.0 CDTI ecoFLEX 130

“May I congratulate you on this diesel tuning product as it has made a noticeable difference to my Land Rover Discovery. I have tried other diesel tuning boxes for my previous vehicles (Kia Sorento, Peugeot 206 and Vauxhall Vectra)... and they all produced slight engine stuttering under certain load conditions. The CHIP Express system does not show any evidence of this and is equal to the likes of an ECU remap (which I have also had done before) for smoothness and noticeable power gains. This would be the only diesel tuning product I would recommend.”

“Be assured, this is NO gimmick. Arrived yesterday (less then 24 hours after the order was placed) and fitted today. The fitting was easy especially with the photos and instructions sent with the chip. The first thing I noticed was the responsiveness of the engine from a standing start, no more lag. I then went on a 30 minute drive both motorway and sideroads and my average fuel consumption went UP from 33.3mpg to 38.7mpg. My motorway speed varied from 60 to 85mph and the sideroads from zero to 40mph. I am so pleased with the whole result. This is worth every single penny paid. Thank you!”

Ford Kuga MK2 2.0 TDCi 163

“As do many, I took the 'if it sounds too good to be true, it probably is' approach to performance chips. But CHIP Express were recommended by an impeccable source who had had experience with their product on my model of car - a Citroën C6 with the 2.7 HDi twin turbo diesel. Following a first rate response to a query, the product has delivered in spades. Ten days and more than 1000 miles of mixed town, country, low and high speed driving later I am certainly getting more than 10% more from a gallon, and probably 15%, and the performance is markedly better. Low speed response is immediate and has eradicated what I took to be baked-in lag in a big automatic turbo diesel, and mid-range acceleration is silky smooth, including up inclines. A very good car has been turned into the excellent car I had hoped for all along.”
