A new ratio option, 0:1 (None), has been added. Selecting this will hide the oil ratio in the results display. This is especially useful if you don’t have a 2‑cycle engine but still use a fuel stabilizer with 4‑stroke engines—for winterizing, seasonal use, or long‑term storage. By default, additives are toggled on!
