The average cost for an oil and filter change is between $14 to $28. Labor costs are estimated between $0 to $1 while parts are priced between $14 to $27.
When to get an oil filter change depends on the condition of your vehicle and driving habits. Since a portion of the engine's oil remains in the filter when the oil is drained, you should chance the oil filter at the same time as the oil. Most oil filters range from $4 to $10.
