About Oil Change
Oil Change was built for the moment you just need to handle this task and move on — no signup, no upload to a third-party server. Processing runs locally in your browser using modern Web APIs. Nothing is uploaded, nothing is logged, and there is no quota to worry about for casual use. If you find yourself doing this regularly, the rest of the utility suite covers most adjacent tasks with the same approach.
