Fuel Efficiency Tips

Save gas and money with our help! With gas prices at record levels, everyone is looking for ways to help save money at the pump. We can offer you many tips to help conserve gas - things you can do and services your GM-trained Goodwrench technician can provide to improve your mileage.

10 Ways You Can Save Gas

1. Go the speed limit. Use cruise control.

Speed limits are calculated for maximum safety - they'll also reward you with maximum gas mileage. You can get up to 20 percent more mileage traveling 55 mph than 70 mph. Using cruise control provides additional gas savings.

2. Drive evenly. Avoid hard stops.

Quick starts burn gas while hard stops also cost you. Take your foot off the accelerator and coast a bit before stopping for a traffic light or a stop sign.

3. Avoid idling and rush hour traffic.

You're burning fuel while idling - up to a gallon every hour. So, avoid rush hour traffic when possible.

4. Open windows at slow speeds. Use A/C on highways.

Around town, turn your air conditioning off and roll down the windows. On the highway, open windows create drag at speeds of 40 mph or more, so roll them up and use the air.

5. Remove junk from the trunk.

Added weight in your vehicle affects fuel economy, so take unnecessary items out of your trunk.

6. Fill up when it's cool and before holidays.

Cooler temperatures in the early morning or late evening create less vapor. Also, getting a fill-up three days before a holiday will help you save on the per-gallon price at the pump.

7. Don't top off gas and tighten the cap.

When buying gas, stop when the pump shuts off automatically. And remember, your tank needs both fuel and fumes, so tighten the gas cap after every fill-up.

8. Use the correct fuel grade.

Use the fuel grade recommended by your vehicle manufacturer. In addition, TOP TIER Detergent Gasoline is even better for your vehicle. It is a class of gasoline with enhanced detergency, that exceed detergent requirements imposed by the EPA. It meets voluntary deposit control standards developed by four automotive companies, including General Motors.

9. Don't accelerate up hill.

Build up speed before an incline, and then maintain it on the way up. Coast on the way down for additional fuel economy.

10. Avoid rooftop carriers.

Approximately one quarter of each gallon of gas is needed to overcome wind resistance, so avoid carrying things on your roof. If necessary, use an aerodynamic carrier to help minimize drag.

Your Oil Life Sensor and Simplified Maintenance

If you're a GM owner and your vehicle is equipped with the GM Oil Life System (OLS), you can use the Simplified Maintenance plan to save time, money and oil. The plan calls for you to visit your GM Goodwrench dealership only when your "Change Oil" light comes on, instead of every 3,000 miles. This also saves environmental waste that can result from too frequent oil changes.

Rain and wet roads can mean driving trouble. On a wet road you can't stop, accelerate or turn as well because your tire to road traction isn't as good as on dry roads. If your tires don't have much tread left, you'll get even less traction.

That portion of a tire that comes into contact with the road. It is distinguished by the design of its ribs and grooves.

It's always wise to go slower and be cautious if it starts to rain while you are driving. The surface may get wet suddenly when your reflexes are tuned for driving on dry pavement.

The heavier the rain, the harder it is to see. Even if your windshield wiper blades are good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road, and even people walking. Road spray can often be worse for vision than rain, especially if it comes from a dirty road.

So it is wise to keep your wiping equipment in good shape and keep your windshield washer tank filled. Keep your windows clean inside. This will make them less likely to fog up. Replace your windshield wiper inserts when they show signs of streaking or missing areas on the windshield, or when strips of rubber start to separate from the inserts.

Driving too fast through large water puddles, or even going through some car washes, can cause problems too. The water may affect your brakes. Try to avoid puddles, but if you can't, try to slow down before you hit them.

Hydroplaning

Hydroplaning is dangerous. So much water can build up under your tires that your vehicle can actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road.

You might not be aware of hydroplaning. You could drive along for some time without realizing your tires aren't in constant contact with the road. You could find out the hard way; when you have to slow, turn, move out to pass - or if you get hit by a gust of wind. You could suddenly find yourself out of control.

Hydroplaning doesn't happen often. But it can if your tires haven't much tread or if the pressure in one or more is low. It can happen if a lot of water is standing on the road. If you can see reflections from trees, telephone poles, or other vehicles and raindrops "dimple" the water's surface, there could be hydroplaning. Hydroplaning usually happens on higher speed roads. There just isn't a hard and fast rule about hydroplaning.

The best advice is to slow down when it is raining, and be careful.

Some Other Rainy Weather Tips

Turn on your headlights - not just your parking lights - to help make you more visible to others.
Look for hard-to-see vehicles coming from behind. What you see through the rearview mirrors may be distorted by raindrops on the outside mirror and rear window. You may want to use your headlights even in daytime if it's raining hard.
Besides slowing down, allow some extra following distance. And be especially careful when you pass another vehicle. Allow yourself more clear room ahead, and be prepared to have your view restricted by road spray. If the road spray is so heavy you are actually blinded, drop back. Don't pass until conditions improve. Going more slowly is better than having an accident.
Use your defogger if it helps.
Have good tires with proper tread depth.

Winter Driving

Getting ready for cold weather

You wouldn't head out into cold weather without bundling up. Your vehicle faces similar challenges as temperatures drop. The bottom line: it needs a little extra care as the mercury plummets. A little preparation before winter sets in may help prevent major headaches later.

What you can do

Make sure you have a heavy-duty ice scraper and snow brush in your vehicle.
Cold weather reduces tire pressure, so check tire pressure often. See your Owner's Manual for directions and details.
In severe winter temperatures, you may have to change the grade of your engine oil. Check your vehicle's Owner's Manual for the viscosity grade recommended for your vehicle's engine.
Check your wiper blades. Cold temperatures can make blades brittle, and ice on the windshield can cause nicks in the blades, decreasing performance.
If you're planning a trip, take a blanket, extra-warm clothing, a collapsible shovel, a bag of road salt and an extra bottle of windshield washer fluid.
Put on snow tires if you live in major snow belt areas. Check your vehicle's Owner's Manual for details and recommended practices.

Often referred to as Winter tires, a special type of tire with a tread and compound that gives better traction in snow and other extreme winter conditions.

What GM Goodwrench can do

Cold weather affects battery efficiency. Most cold-weather breakdowns occur because batteries aren't delivering full cranking power. Your GM Goodwrench technician can check your battery and make sure battery cables are corrosion-free.
Winter will take a big toll on your vehicle. Make sure your vehicle is ready. See your GM dealer for a fall season Multi-Point Vehicle Inspection, including checks on wiper blades, tires, fluids and more.

Safe Driving

Buckle Up

The most important tip to keep your family safe while driving is to always use safety belts and proper child restraints. Children are safer when placed in the rear seat in the appropriate infant, child, booster seat, or safety belt - appropriate for the size and age. Never place a rear facing infant restraint in the front seat of a vehicle equipped with an active air bag.

Both Hands on the Wheel!

The first car safety tip is to always drive with both hands on the wheel. The best place for your hands are at the nine and three o'clock positions, which help provide greater control when steering.

Lights On, Please

With your safety in mind, all new GM vehicles come equipped with daytime running lamps. To help with safe driving, turn on your lights in rainy or snowy weather to make sure that your headlamps, taillamps and other exterior lamps are on. Even if your visibility is good, other drivers will have a better view of your vehicle.

Snow on the Roof

Don't let snow pile up on top of your car or truck. Peaks of snow increase drag and decrease gas mileage. And snow piled in your pickup's bed can obstruct both your view and the view of other drivers.

Quick Maneuvering

If you need to veer suddenly to avoid hitting an object in your vehicle's path, before turning, make sure you look in the direction you'd like to head towards to make sure the path is clear.

Alcohol is a Factor in Many Traffic Fatalities

These visual signs may help you spot an impaired driver:

Stopping problems (too far, too short, or too jerky)
Straddling a lane line
Swerving or drifting
Weaving across lane lines
Accelerating or decelerating for no apparent reason
Slow response to traffic signals
Turning with a wide radius
Driving without headlights at night
Varying speed
Stopping in a lane for no apparent reason
Failure to signal or signal inconsistent with action

Let An Expert Inspect

Making sure your vehicle is in peak condition is another excellent way to help you drive safely. Stop by your GM dealer and let a Goodwrench technician give your GM vehicle a Goodwrench Multi-Point Vehicle Inspection. Your technician checks many areas (27 points in all) that can assist in safe driving - including wiper blades, windshield cracks, tire wear, brakes, steering, suspension and taillamps - and will offer expert Goodwrench services if you need them.
