Replace a dirty air filter

Change your air filter as recommended. Between changes, inspect it by taking the filter out and tapping it against a hard surface. If dirt falls out, replace the filter. Doing so can improve fuel economy by up to 10%.

Oil Level

You'll get a more accurate dipstick reading if you wait a few minutes after turning off the engine. This gives the oil in the crankcase time to drain back into the oil pan. Also, make sure the vehicle is on level ground.

Consider changing your cabin air filter

If you spent much of the winter coughing and sneezing you might want to replace your cabin air filter and thoroughly vacuum interior surfaces.

Replacement Tires

Manufacturers provide detailed specifications on each replacement tire, making tire selection easier.

Look for the symbol

If the tire is not marked with the "Mountain Snowflake Symbol", it is not an approved winter tire.

Performance Tires

Always consult the manufacturer's specifications and guidelines on performance tire use.

Tire Failure

Overloading a truck tire can cause excessive heat buildup, leading to tire failure.

Tire Wear

Tread wear grades are only valid when comparing tires from the same manufacturer.

Register Your New Tires

When you buy new tires, fill in and return your tire registration form. In the event of a recall, the manufacturer will contact you. In many cases, you can register online.

Getting Maximum Traction

For maximum traction in wet or snow conditions, replace tires before they reach minimum tread depth.

Handling and Safety

Always install the same type of tire on all four wheels to ensure proper handling and safety.

New Tires

Be careful when you take your new tires on the road. Every tire requires a break-in period during which handling and traction will be slightly compromised.

Tire Pressure

Reducing tire pressure to increase traction doesn't work. Driving on under-inflated tires is dangerous any time of year.

Tire Damage

In the event of striking an object on the road, find a safe area to stop and inspect your vehicle. Report any noticeable damage to a GM Goodwrench technician.

Rotating Your Tires

After rotation of your tires, adjust front and rear tire pressure as indicated on the Tire-Loading Information label.

Tire Pressure Reading

To get a true tire pressure reading, check the tires when they're cold -- when your vehicle has been idle for at least three hours.

How Much Pressure?

A label on the underside of the trunk lid or on the edge of the driver's door will tell you the proper tire inflation for your car or truck.

Tire Tread

Tires with less than 1.6 mm of tire tread depth or visible treadwear indicators in three or more places should be replaced as should tires with bulges, splits or cracks.

Ensure tires are properly inflated

Take five minutes every month to check your tire pressure. Under-inflated tires can increase your fuel consumption by 3% and lead to reduced tire life-spans, which means more worn tires in our landfills.

Tire tread - measure it and inspect it

Tires with treads worn down to the same level as the tread wear indicator (1.6 mm or 2/32 of an inch in depth) should be replaced. Proper treads allow for normal handling of your vehicle and as a result more efficient fuel consumption.

Loss of Pressure

Tires will lose pressure when the temperature gets colder. The general rule provided by tire manufacturers is 7kPa or 1psi drop for every 5 degree Celsius change, so measuring tire pressures year-round is vital.

Tire Inflation

Over-inflated tires wear out more quickly in the center of the tread. Under-inflated tires wear out more quickly at the outer edge of the tread. With under-inflated tires, rolling resistance is increased causing increased fuel consumption.

All-season vs. winter tires

Although all-season tires can be used in a moderate winter environment, winter tires provide the best cold weather performance below 7°C. This includes wet and dry in addition to snow/ice/slush surfaces where greater tread flexibility leads to better grip.

Keep your brakes in top shape

Improperly maintained brakes can result in unwanted drag. This unnecessary resistance can substantially increase fuel consumption.

Go the speed limit. Use cruise control.

Driving the speed limit helps maximize gas mileage. Cruise control may also maximize gas mileage by maintaining your vehicle at a constant speed.

Drive evenly. Avoid hard stops.

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

Wheels and Rims

The wrong wheel/rim can cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlight aim, as well as bumper height and ground clearance.

Driving Out of a Skid, Backward and Forward

The best way to drive out of a skid is to take your foot off the accelerator, steer in the direction you want to go and constantly check for an escape route.

Quick Maneuvering

If you need to turn the wheel suddenly to avoid hitting an object in the path of your vehicle, look in the direction you're turning. If you look at the object, you're more likely to hit it.

Avoid idling and rush hour traffic

You're burning fuel while idling - up to a 3.79 litres every hour. So, avoid rush hour traffic when possible.

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 efficiency.

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

Air conditioners and heaters are efficient on the highway, but they can increase your fuel consumption by up to 12% in stop-and-go traffic.

Replace worn wiper blades

Your wiper blades may not be cleaning your windshield properly if you haven't replaced them in the past 12 months. Consider replacing them to ensure a cleaner windshield and to avoid over using your washer fluid.

Take care of your windshield

Make sure your vehicle has antifreeze rated for the coldest weather. It's also a smart idea to replace your windshield wipers every year before winter begins or purchase winter rated windshield wipers.

Lights On, Please!

In rainy or snowy weather, turn on your headlamps and tail lamps. Even if your visibility is good, other drivers will have a better view of your vehicle in their rearview mirrors.
