Last month, we discussed how proper vehicle maintenance can improve gas mileage. In this article, we’ll delve into driving techniques that will further boost fuel economy.

First of all, though, I would like to thank Mr. Rorden of Los Altos, who sent an e-mail to suggest that, when ordering a new car, a person should select the base engine rather a more powerful optional engine. He makes a good point.

Unless you are purchasing an SUV or light truck for trailer-towing duty, there is usually no need for an engine more powerful than the standard one. I would also add that, if a hybrid vehicle fits your needs, consider buying one.

While not the ultimate answer to our oil supply and air pollution woes, hybrids are the most fuel efficient and cleanest vehicles currently available. Being able to use the car pool lane as a single occupant is nice, too.

The high cost of fuel in Europe has driven the market for lighter vehicles with economical small-displacement engines. I only wish that we had half the selection of small cars that Europeans do. Brands that long ago disappeared from the United States, such as Fiat, Renault and Citroen, are alive and well in Europe, building thoroughly modern cars that are very fuel efficient, yet nimble and fun to drive.

So, on the subject of driving habits to boost mileage … First and foremost, slow down! I know, easier said than done, but you might find some unexpected benefits. In the past few weeks, I have made an effort to drive our local freeways at about 60 to 65 mph as compared to my previous 70 to 75 mph cruising speed. In addition to realizing fuel savings of about 10 percent, I find that I arrive at my destination feeling more relaxed, and that the difference in driving time is insignificant.

Driving at a constant speed as much as traffic will allow saves fuel. Some drivers are in the habit of constantly accelerating to fill gaps in traffic, only to brake as they approach the car in front of them. Each time you brake, energy of motion generated by burning that expensive gas is converted to waste heat and additional brake wear.

Leaving a bit of space between your vehicle and the one ahead allows you to maintain a more constant speed. Good drivers don’t use their brakes much. Professional truck drivers are especially adept at this technique. Using the cruise control whenever possible is a good idea also.

Of course, along with maintaining a constant speed, avoiding rapid acceleration minimizes fuel consumption. The basic idea is to maintain a light touch on both the throttle and brake.

A car is at its most fuel inefficient and polluting when it’s cold, so try to combine several short trips into one longer trip. This has the added benefit of reducing wear and tear on your engine.

Try to keep unneeded weight (golf clubs, what have you) out of the trunk. More weight requires more fuel to propel the car.

If possible, remove unused roof racks. These cause significant additional air drag, lowering gas mileage.
