The Environmental Protection Agency on Friday approved a new rule that would require automakers to make engine oil changes on their vehicles.
The rule, which EPA says will save up to $8,000 in fuel costs per vehicle, is expected to be final by the end of the year.
The EPA says it’s also moving to implement the rule in 2018.
Under the rule, automakers would be required to report to the EPA how much fuel they’re using on a daily basis and how often they change oil.
EPA says the cost of changing engine oil could range from $1.70 to $2.20 per gallon.
The agency says this would save automakers $1 billion over the next 10 years.
The auto industry already uses a proprietary engine oil-change technology.
The EPA says there are about 5 million vehicles on the road today.
The agency says that number will grow to 8 million by 2025.
