The 2018 Ram 1500 uses an engine oil filter to capture debris carried by the oil, helping keep circulating oil filtered as the engine operates. At Larry H. Miller Dodge Ram Peoria in Peoria, AZ, an oil filter service replaces the filter matched to the engine actually fitted, renews the drain plug gasket or washer where applicable, and checks the filter seal for leaks after the engine runs. The manufacturer’s maintenance schedule calls for the oil filter to be replaced every 10,000 miles. Booking this service with the oil change helps prevent a loaded filter from opening its bypass valve and sending unfiltered oil through the engine. Schedule service with the Peoria service team.
What an oil filter replacement on a 2018 Ram 1500 involves
An oil filter replacement for a 2018 Ram 1500 begins with fitting a filter matched to the engine’s specification. The correct match matters because the filter must work with the engine’s oil-flow requirements and sealing surface. During the service, the drain plug gasket or washer is replaced when the engine uses one, helping renew the seal at the drain point as the oil service is completed.
After the filter is installed and the oil service is completed, the engine is run so the filter seal can be checked for leaks. This final check helps confirm that the filter is seated correctly before the vehicle leaves the service area. The manufacturer’s maintenance schedule specifies oil-filter replacement every 10,000 miles for this model year. When your 2018 Ram 1500 reaches that interval, schedule service so the filter and oil are handled together.
Why the filter matters on a 2018 Ram 1500
The 2018 Ram 1500 is offered with engines ranging from 2,988 to 5,654 cc and from six to eight cylinders, depending on configuration. As engine oil circulates, it carries small debris away from moving components. The oil filter holds that debris so the oil returning through the engine is filtered rather than carrying the collected material onward.
A filter can eventually load with the debris it captures. Once that happens, its bypass valve opens. A loaded filter does not stop the engine getting oil; it stops the engine getting filtered oil, and that is worse in a quiet way because circulation continues while filtration is reduced. That is why the filter is replaced with the oil instead of being stretched across two changes. For this model year, the manufacturer’s schedule calls for replacement every 10,000 miles, helping keep routine maintenance tied to a clear service point.

Frequently Asked Questions
6 common questions answered
Is the oil filter replaced every time a 2018 Ram 1500 has its oil changed?The oil filter is replaced with the oil at the scheduled service interval for a 2018 Ram 1500, which the manufacturer identifies as every 10,000 miles.
Replacing both together prevents a loaded filter from being carried into another oil cycle. The filter captures debris from the oil, and its bypass valve opens when the filter loads. The vehicle’s service history and the manufacturer’s schedule determine when the next service is due.
Filter matched to the installed engine
Drain plug gasket or washer renewed where applicable
Filter seal checked after the engine runs
What is included in an oil filter replacement on a 2018 Ram 1500?An oil filter replacement on a 2018 Ram 1500 includes an engine-matched filter, a new drain plug gasket or washer where applicable, and a post-service leak check.
The service covers the filter and its sealing points in sequence. After installation, the engine is run so the filter seal can be checked for leaks. The filter is replaced alongside the oil rather than carried into a second change.
Filter matched to the engine specification
New drain plug gasket or washer when used by the engine
Leak check at the filter seal after operation
What happens if the oil filter on a 2018 Ram 1500 is not replaced?If the oil filter on a 2018 Ram 1500 is not replaced, it can load with debris and open its bypass valve, allowing unfiltered oil to circulate.
A loaded filter does not necessarily stop oil flow; it stops the engine getting filtered oil. An oil-pressure warning, unusual engine noise, or oil that darkens quickly after a change can be reasons to arrange an inspection. The service history and manufacturer’s schedule help determine the appropriate maintenance point.
Debris remains held in an increasingly loaded filter
The bypass valve may open
Oil can circulate without normal filtration
Does a 2018 Ram 1500 need a specific oil filter?Yes, the filter is matched to the 2018 Ram 1500 engine fitted, and filters are not interchangeable across engines.
This model year can use engines ranging from 2,988 to 5,654 cc and from six to eight cylinders, depending on configuration. The installed engine determines the correct filter match. A service appointment allows the filter to be selected for that engine without naming a part number or relying on a one-size-fits-all assumption.

Can the oil be changed on a 2018 Ram 1500 without changing the filter?The oil can be drained and replaced separately, but the 2018 Ram 1500 oil filter should be replaced with the oil according to the manufacturer’s schedule.
The filter holds debris carried by the oil and can load over time. Once its bypass valve opens, oil continues circulating but may be unfiltered. The manufacturer’s published interval for replacing the oil filter on this model year is every 10,000 miles, with service history helping determine the next due point.
Oil carries debris away from engine components
