See your owners manual or call one of our service advisers for more information. Low and used coolant also causes your vehicle to be less fuel efficient. In some cases this can decrease your miles per gallon by up to 10%. If your coolant is left unchanged for too long may result in a chemical condition known as electrolysis, this can result in costly repairs or even an engine replacement.
From a safety standpoint an overheated engine won’t pose a problem for other motorists, but could leave you stranded with no warning. From an environmental point of view, there is significant impact. Because leaking engine coolant is poisonous and could be ingested by children, pets and other animals.
Check your owner’s manual for the manufacturer’s recommended intervals. But depending upon where and how you drive, a good rule of thumb is every 12 months or 12,000 miles. As air filters get clogged with dirt, grime, and debris, the volume of take air is restricted, decreasing performance and engine power.
If ignored long enough, a contaminated air filter can cause your engine to work harder negatively impacting both efficiency and economy. There’s little safety risk, just decreased power and performance, but neglecting your air filter can have a big impact on the environment.
