IM MET
How to Use This Tool
- Enter miles since your last oil change.
- Enter your recommended oil change interval.
- Enter the cost of a standard oil change.
The Formula
Remaining = Interval - Last Change. Annual Cost = Changes per Year × Cost.
Why It Matters
Your car recommends oil changes every 7,500 miles. At 15,000 miles/year, you need 2 changes annually at $60 each ($120/year). Switching to synthetic oil (10,000-mile intervals) saves $30-60/year.
