Vehicle Care Tips

OIL PRESSURE

You'll get a more accurate dipstick reading by waiting a few minutes after turning off the engine, giving the oil time to drain from the crankcase into the oil pan. And make sure the vehicle is on level ground!

In severe weather 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.

BATTERIES

Cold weather affects battery efficiency. Check to make sure battery cables are corrosion-free. Build up on the battery cables can drain your battery.

Most cold-weather breakdowns occur because batteries aren't delivering full cranking power.

TIRE PRESSURE

Maximize your tires' performance and durability by monitoring and maintaining correct air pressure.

Air is a gas, expanding when heated and contracting when cooled. For most of North America, fall and early winter are especially important times for checking tire pressure - as the ambient temperature falls, tire pressure goes down.

A good rule of thumb is that every 10 degrees Fahrenheit temperature change, tire pressure changes about 1 psi - higher as temperature rise, lower as they fall. Also, check your vehicle's Owner's Manual for recommended tire pressure.

 

Under-inflated tires can cause:

  • Premature of irregular wear
  • Poor handling
  • Reduced fuel economy

Over-inflated tires can cause:

  • Unusual wear
  • Poor handling
  • Reduced fuel economy

Checking Air Pressure

Check your vehicle's tires at least once a month, when the tires are cold (let the vehicle sit for at least 3 hours). Look in your owner's manual for the recommended tire inflation for your vehicle. Use a quality gauge. Don't "eyeball" tires - radial tires can look fine even when they're under-inflated.

Be sure to look for objects that have become wedged in the tread - they can work themselves further into the tire and cause air loss.

And don't forget to check the spare!
