Free car tools
Working calculators, not articles — the same math SteerLog runs on your logged entries, free in your browser. Nothing is saved or sent. More tools and guides are on the way.
Calculator
Oil Change Interval
Oil type + driving style → how many miles your oil is actually good for, and when the next change lands.
Calculator
Cost Per Mile
A year of costs ÷ your miles → what driving really costs you, with AAA and IRS benchmarks.

Maintenance Schedule by Mileage
Your odometer → what's due now and what's coming, on the 30k/60k/90k pattern.
