Maintenance and the Environment

Vehicles with properly maintained engines and emission control systems pollute less and are more fuel efficient. They perform better, last longer, have higher resale value and save you money. Here are some tips for keeping your vehicle running at top efficiency.

  • Follow GM's maintenance guidelines to help identify any problems before they become serious. Your Owner's Manual provides recommended maintenance intervals and product specifications.
  • If you notice a change in the way your vehicle functions or if your fuel efficiency drops, get your vehicle checked promptly.
  • Change your vehicle's oil regularly. The GM Oil Life System (OLS) tells you when you need to change your oil, saving you time and money, and keeping you reassured that your oil is in good condition. If the GM OLS is used as intended, almost 378 million litres of oil could be saved worldwide in the next five years. Your Goodwrench Dealer is equipped to properly dispose of waste oil.
  • Change the air filter as often as the manual recommends. Between changes, inspect it by taking the filter out and tapping it against a hard surface. If dirt falls out, replace the filter.
  • Do a tire check-up. Every two weeks, check your tire treads and sidewalls for wear, cuts or bruises. Follow it up by checking your tire pressure. Maintaining the correct tire pressure increases safety, saves you money and reduces pollution.
  • Check your antifreeze/coolant level weekly. Never remove the radiator cap unless the engine is cold!
  • Let the expert technicians at Goodwrench Service keep your vehicle tuned up. The fuel efficiency of most cars can be improved by as much as 6 percent with a minor tune-up, saving you money and reducing your vehicle's carbon footprint.
  • Keep the brakes maintained. Being able to brake quickly can help you avoid an accident. Make sure the vehicle stops smoothly and does not pull to one side when the brakes are applied.
